Dear readers,<br />
Waste not, want not…<br />
The news that German chipmaker Infineon is heading a <strong>Europe</strong>an research<br />
project focusing on reducing e-waste (page 10) will come as no surprise<br />
to an industry in which efficiency has long been king. Our cover feature<br />
(page 16) reveals how inspection-based process control tools could save<br />
you both time and resources. And can Marie Kondo-ing your benchtop<br />
reduce the number of boards landing on the scrap pile? Find out more on<br />

Labour-saving digitalization?<br />
We typically view automation solutions as digital replacements for human<br />
operators, but could increased digitalization actually help companies<br />
attract more talented personnel (page 30)? If robotics is more your thing,<br />
don’t overlook the advantages of no-code and low-code software<br />
solutions (page 48).<br />
The future of electronics production<br />
“The next paradigm shift will be in the area of software. And artificial<br />
intelligence will be the driver,” says Andreas Tuerk in the article on page<br />
52. The organizers of this year’s Productronica event agree (page 14). AI,<br />
automation, and the growing significance of power electronics will be<br />
front and centre in Munich in November.<br />

Electromobility & power electronics applications<br />
Heraeus Electronics to partner in joint ‘KuSIn’ project<br />
Source: Heraeus Electronics<br />
Provider of material solutions for electronics packaging<br />
Heraeus Electronics is one of five partners taking<br />
part in the three-year project ‘KuSIn – Copper sinter<br />
processes using induction heating for electromobility<br />
applications’, funded by the German Federal Ministry<br />
of Economic Affairs & Climate Action (BMWK), and<br />
launched in July 2023. The other participants are: Vitesco<br />
Technologies, Chemnitz University of Technology<br />
and Fraunhofer Institutes ENAS and IMWS.<br />
The project aims to develop pastes, tools, machines, and<br />
processes for inductive sintering of copper particles for<br />
(multi-)die and substrate attach (the technical terms<br />
for chip and substrate assembly on the circuit carrier) in<br />
electromobility, and related power electronics applications.<br />
Copper will replace silver as a joining material.<br />
Energy-efficient inductive heating will be used to address<br />
the higher sinter temperatures and oxidation tendency<br />
of copper. This is expected to reduce process<br />
costs and improve energy efficiency while maintaining<br />
reliability. Increased sintering of metal-ceramic substrates<br />
on heat sinks or other large-area structures<br />
could further support the spread of low-temperature<br />
sinter technology in power electronics. Heraeus will develop<br />
copper pastes and processes for inductive sintering<br />
of copper particles for die and substrate attach in<br />
power electronic assemblies.<br />

<strong>Europe</strong>an Commission launches risk assessments of critical technologies<br />
IPC urges holistic approach to include complete electronics ecosystem<br />
IPC has issued a statement in response to<br />
the <strong>Europe</strong>an Commission’s announcement<br />
that it will be carrying out risk assessments<br />
of technology areas deemed critical for the<br />
EU’s economic security. The Commission<br />
identified four technology areas that are<br />
considered highly likely to present the most<br />
sensitive and immediate risks related to<br />
technology security and technology leakage.<br />
These are: advanced semiconductors,<br />
artificial intelligence, quantum technologies<br />
and biotechnologies.<br />
It recommends Member States initially<br />
conduct collective risk assessments of<br />
these four areas by the end of this year.<br />
“We need to continuously monitor our<br />
critical technologies, assess our risk exposure<br />
and – as and when necessary – take<br />
measures to preserve our strategic interests<br />
and our security,” Commissioner for<br />
Internal Market, Thierry Breton, said. “<strong>Europe</strong><br />
is adapting to new geopolitical realities,<br />
putting an end to the era of naivety<br />
and acting as a real geopolitical power.”<br />
IPC statement<br />
In response, IPC urged the EU to consider<br />
the electronics ecosystem as a whole and<br />
emphasized the strategic importance of a<br />
robust electronics manufacturing industry<br />
in <strong>Europe</strong>. Alison James, IPC senior director<br />
of <strong>Europe</strong>an government relations,<br />

said: “IPC urges the <strong>Europe</strong>an Commission<br />
to address the alarming strategic dependencies<br />
in <strong>Europe</strong>an electronics<br />
manufacturing as part of and independently<br />
of the risk assessments on critical<br />
technologies ... Electronics manufacturing<br />
is central to the four critical technologies<br />
highlighted in the Commission’s proposal<br />
although key segments of electronics<br />
manufacturing in <strong>Europe</strong> have atrophied,<br />
undermining the region’s resiliency, security,<br />
and economic competitiveness.<br />
“IPC recently led a collaboration of more<br />
than 100 companies across the electronics<br />
industry to produce a report for<br />
the <strong>Europe</strong>an Commission ... The industry<br />
stakeholders ... agreed that <strong>Europe</strong> must<br />
strengthen the electronics manufacturing<br />
industry to remain on the forefront of<br />
technological innovation, compete in the<br />
global economy, and bolster resiliency<br />
against future supply chain disruptions.<br />

TEST & QUALITY ASSURANCE » Special<br />
Interview with Guenter Lauber, ASMPT, on carbon neutrality<br />
The road to sustainability<br />
ASMPT, a global leader in hardware and software solutions for the semiconductor and<br />
electronics manufacturing industries, recently unveiled its strategy for carbon neutrality.<br />
Guenter Lauber, EVP & Chief Strategy and Digitalization Officer, responsible for<br />
ESG in ASMPT’s management, spoke to <strong>EPP</strong> <strong>Europe</strong> about the company’s plans.<br />
Our vision proclaims: “Shaping a bright &<br />
sustainable future for customers, employees,<br />
investors, partners and society”<br />
Source: ASMPT<br />
<strong>EPP</strong> <strong>Europe</strong>: We‘re pleased to hear that<br />
ASMPT aims to be carbon neutral by<br />
2035...<br />
Guenter Lauber: Wait a minute, let me<br />
stop you there and clarify that our goal is<br />
Net Zero 2035 for Scope 1 and Scope 2.<br />
This means that we want to become carbon<br />
neutral in terms of our direct<br />
emissions - from heating systems or company<br />
vehicles (Scope 1), for example, and<br />
indirect emissions from our electricity<br />
suppliers (Scope 2). As with all statements<br />
about sustainability, it is very important<br />
to be precise and transparent regarding<br />
the framework you are referring<br />
to – as we are in our ESG Reports. Anyone<br />
who makes overly general statements<br />
about sustainability will rightly have to<br />
put up with the accusation of greenwashing.<br />
Can you provide a bit more insight into<br />
ASMPT’s sustainability goals?<br />
ASMPT’s ESG strategy is based on UN<br />
SDGs 3, 4, 5, 7, 8, 9, 11, 12, and 13. But let<br />
me be a little more specific. Although<br />
sustainability and ESG are highly complex<br />
topics that affect all processes, departments,<br />
segments and regions of ASMPT,<br />
we have already made good progress in<br />
this field. In the area of governance, we<br />
have carried out our risk assessment, established<br />
our processes, and are actively<br />
meeting the requirements placed on us by<br />
governments and markets. We have published<br />
an ESG Report, in which we disclose<br />
ESG targets and results, since 2017,<br />
for instance.<br />
What is your new net-zero strategy?<br />
To achieve a CO 2<br />
-free footprint as quickly<br />
as possible, we decided some time ago to<br />
switch to solar and wind power and to<br />
save energy in all areas of the company.<br />
What is new is that we have defined a<br />
roadmap and published our commitment<br />
to a concrete goal. In so doing, we are<br />
challenging ourselves and, at the same<br />
time, wanting to live up to the responsibility<br />
we have through our prominent<br />
position in the industry – an industry<br />
which Dr. Isabel Al-Dahir, technology<br />
analyst at IDTechEx, says accounts for up<br />
to 4 percent of global greenhouse gas<br />
emissions. Regardless of how high the<br />
value really is, it is clear we must not<br />
stand still.<br />
You already mentioned that companies<br />
must focus on the sustainability goals<br />
that are most relevant to them, but that<br />
this is also determined by economic factors.<br />
How does this apply at ASMPT?<br />
Traditionally, profitability assessments<br />
have been dominated by the interests of<br />
shareholders, often at the expense of<br />
other interest groups. Sustainability initiatives<br />
were thus often rejected by the<br />
argument “no customer is going to pay us<br />
for that”. But this has changed. Not least<br />
because products that do not meet customers‘<br />
sustainability requirements will<br />
not be sold in the future. Sustainable<br />
companies are redefining the business<br />
ecosystem by designing models that create<br />
value for all stakeholders, including<br />
employees, shareholders, supply chains,<br />
society, and the planet. In terms of the<br />
environment, we have prioritized topics<br />
based on the materiality matrix. While<br />
climate change, greenhouse gas<br />
emissions, energy-efficient products and<br />
energy management are of great importance<br />
to our stakeholders, they also have a<br />
major impact on ASMPT’s business. The<br />
economic benefits of some measures are<br />
obvious: energy-efficient products are<br />
more attractive, and energy-saving<br />
measures, including generating your own<br />
energy, pay for themselves after a certain<br />
period of time. The positive impact on the<br />
recruitment of workers, especially the<br />
younger generation, is equally obvious.<br />
What is often overlooked, however, is<br />
that, according to recent reports, investors<br />
are increasingly using companies’<br />
non-financial disclosures to make investment<br />
decisions. In one meta-study, 90<br />
percent of 200 studies analyzed concluded<br />
that good ESG standards reduce<br />
8 <strong>EPP</strong> <strong>Europe</strong> » 11 | 2023
the cost of capital; 88 percent show that<br />
good ESG practices lead to better operational<br />
performance, and 80 percent<br />
show that share price performance is<br />
positively correlated with good sustainability<br />
practices. The development of sustainable<br />
alternatives in products and operational<br />
processes is a driver of innovation.<br />
How exactly does ASMPT<br />
approach ESG, SDG and net-zero?<br />
Our vision proclaims: “Shaping a bright &<br />
sustainable future for customers, employees,<br />
investors, partners and society”.<br />
All employees must be able to develop<br />
awareness of ESG and sustainability issues<br />
in general, and of ASMPT’s focused<br />
activities in particular. To achieve this, we<br />
have established a central and crossfunctional<br />
Environmental, Social & Governance<br />
(ESG) Team. This global team focuses<br />
on achieving our ambitious netzero<br />
targets across all ASMPT segments.<br />
It has also defined and communicated our<br />
net-zero targets for Scopes 1 and 2. To<br />
this end, we have identified the most effective<br />
emission-reducing levers and<br />
measures, prioritized, and selected suitable<br />
and proven practices for CO 2<br />
avoidance,<br />
and provided the necessary financial<br />
resources. With a focus on our targets,<br />
these measures are reviewed and reported<br />
on every two months at each<br />
ASMPT site.<br />
What kinds of measures would those be?<br />
Measures to reduce emissions include, for<br />
example, reducing the energy demand at<br />
each of our sites by investing in new systems.<br />
Others include generating electricity<br />
from renewable sources in-house, and<br />
the electrification of vehicles. All this is<br />
supported by OpEx measures, such as the<br />
procurement of electricity from renewable<br />
energy sources and the purchase of<br />
green electricity and CO 2<br />
compensation<br />
certificates. When discussing such<br />
measures, we must consider each location<br />
separately. We cannot generate<br />
our own energy at will at all our locations,<br />
and not all our sites have providers<br />
who supply electricity from renewable<br />
sources.<br />
Can you give us a few examples of<br />
measures that have already been taken?<br />
Let me mention a few. Since 2019, we<br />
have achieved some initial success with<br />
our ESG measures and reduced CO 2<br />
emissions by 30 percent at our sites in<br />
Munich, Weymouth and Singapore. A few<br />
months ago we completed the installation<br />
of more than 1,200 solar panels at<br />
our global headquarters in Singapore.<br />
Solar panels are also already in use in<br />
Weymouth, UK, and in Huizhou, China.<br />
You mentioned that your Net Zero 2035<br />
program applies to Scope 1 and Scope 2<br />
of the Greenhouse Gas Protocol. What<br />
are your plans for Scope 3?<br />
Scope 3 refers to indirect emissions resulting<br />
from activities along the supply<br />
chain. This includes pollutant emissions<br />
which result from purchased goods and<br />
services, the use of products by customers,<br />
and the transportation of goods to<br />
customers – all highly complex issues.<br />
ASMPT has started to define the basics of<br />
Scope 3 emissions, such as those from the<br />
use of our products, whose energy efficiency<br />
is an issue that has long been close<br />
to our hearts. We are in the process of<br />
measuring Scope 3 emissions so that we<br />
will be able to set Scope 3 targets and reduction<br />
pathways. But reducing Scope 3<br />
emissions is not possible without cooperation<br />
across the industry. This is one of<br />
the reasons we launched the Semiconductor<br />
Climate Consortium (SCC) in<br />
November 2022 as a Leadership Level<br />
founding member. The SCC is the first<br />
global consortium of semiconductor companies<br />
that focuses on reducing greenhouse<br />
gas emissions. We hope that the<br />
consortium will empower each member<br />
to make an impact that goes far beyond<br />
its individual capabilities to combat climate<br />
change.<br />
Finally, what advice would you give to<br />
colleagues in the industry who are still<br />
in the very early stages of ESG?<br />
In a few words: do not be deterred by<br />
tasks that may seem complex at first.<br />
Educate yourself and identify possible<br />
starting points for your company. Just get<br />
started and take it one step at a time.<br />
Even if some measures seem like a drop in<br />
the ocean, we know many drops add up<br />
to the ocean.<br />
Mr. Lauber, we thank you for this interview.<br />

International Federation of Robotics - addressing labour shortages<br />
Online platform to raise awareness of advantages of robotics<br />
Source: International Federation of Robotics<br />
The International Federation of Robotics (IFR) has<br />
launched a new online platform called Go4Robotics<br />
to raise awareness of the advantages of robotics and<br />
provide independent guidance for companies on<br />
their automation journey.<br />
“Labour shortage has become one of the most pressing<br />
challenges for small and mid-sized enterprises<br />
(SME) in OECD countries,” the IFR said. “The manufacturing<br />
sector has been hit especially hard by high<br />
job vacancy rates. Since robots are becoming easier<br />
to install, implement and operate, SMEs have greater<br />
access to automation.”<br />
“The lack of skilled labour is a strong driver for automation<br />
in many countries,” said Dr Susanne Bieller, IFR´s<br />
General Secretary. “In fact, statistics from the EU say that<br />
three quarters of all companies across the EU have a<br />
problem attracting workers with the required skills.”<br />
Given a choice, many young people prefer to work in<br />
a company that uses future technology. If there is a<br />
robot operating on the shopfloor, the employer can<br />
advertise a job to prospective employees as work<br />
that involves controlling a robot. This can often be a<br />
game-changer.<br />
The new online platform by IFR raises awareness of<br />
the many advantages robotics provide. Small and<br />
mid-sized enterprises can find educational content<br />
and an automation checklist. Experts on the platform<br />
dispel myths about segments that are relatively new<br />
to automation, and managers can learn how to<br />
benefit from trends like easy-to-program robots.<br />

<strong>Europe</strong>an EECONE project to reduce e-waste<br />
Infineon to head EU research project for ‘greener’ electronics industry<br />
German semiconductor manufacturer<br />
Infineon Technologies has taken over as<br />
head and coordinator of the research project<br />
EECONE (<strong>Europe</strong>an ECOsystem for<br />
greeN Electronics), which aims to drive<br />
sustainability in the <strong>Europe</strong>an electronics<br />
industry by reducing e-waste. 49 partners<br />
are participating in the EUR 35 million<br />
project. EUR 20 million will be provided<br />
by the EU and the governments of the<br />
partners. The research project was inaugurated<br />
on 20 September 2023 in Toulouse,<br />
France and will run for three years.<br />
Project aims<br />
The goal of EECONE is to dramatically reduce<br />
the consumption of valuable resources<br />
in electronics production. To<br />
achieve this, the project aims to research<br />
more efficient methods of recycling, repairing,<br />
and reconditioning electronic<br />
components, as well as exploring alternative<br />
materials. The project will also<br />
focus on minimizing non-recyclable<br />

waste and enhancing recycling systems.<br />
“Electronics are fundamental to improving<br />
the sustainability of many applications.<br />
But this is not sufficient, electronics<br />
themselves have to become<br />
greener,” said Constanze Hufenbecher, Infineon<br />
Management Board member and<br />
Chief Digital Transformation Officer. “Infineon<br />
is pleased to take on the lead role<br />
in the research project EECONE in order<br />
to advance the circular economy together<br />
with our partners along the value chain.<br />
The only way to achieve sustainability<br />
from design and use and all the way to<br />
recycling is by working together.”<br />
Applications in various sectors, including<br />
automotive, consumer electronics, health,<br />
information and communication, aviation,<br />
and agriculture, will be investigated.<br />
Key focus areas include reducing<br />
material usage by making circuit boards<br />
thinner or smaller and introducing materials<br />
that are easier to separate during<br />
recycling.<br />
The project will also look at ways to facilitate<br />
the replacement of circuit board<br />
and semiconductors to make it easier to<br />
repair devices and make it possible to<br />
reuse and recycle electronic components.<br />
The research will also look at developing<br />
technologies which generate and store<br />
power in IoT devices. Tools for more sustainable<br />
electronic design, including<br />
comprehensive impact assessments for<br />
the use of electronics, are also planned.<br />

Shaping the future of electronics production<br />
Productronica to foreground<br />
AI, power electronics<br />
AI in electronics production, automation, and the growing significance of power electronics<br />
will be major focus topics at this year’s trade show, organizers say.<br />
Productronica 2021 - the last time the event was held - was affected by social<br />
distancing and extensive safety measures as a result of the Covid-19 pandemic<br />
Having taken place mid-pandemic, Productronica<br />
2021 attracted 894 exhibitors from 36<br />
countries and about 20,000 visitors from nearly 70<br />
countries. This may sound like a large number but,<br />
according to Exhibition Director Barbara Mueller,<br />
Productronica 2023 numbers are expected to instead<br />
reflect those from four years ago, in 2019 - when<br />
1,500 companies from more than 40 countries exhibited,<br />
and over 44,000 visitors were in attendance.<br />
So what can they expect to see?<br />
Mueller explained that, alongside overarching<br />
topics such as the shortage of skilled workers and<br />
sustainability, this year’s event will focus on power<br />
electronics, AI, sensors, and the second generation of<br />
quantum technologies. To reflect this, a programme<br />
of lectures and live demonstrations on these key<br />
areas will take place in Hall B2, Stand 448 in collaboration<br />
with the Productronics division of the<br />
VDMA, the conceptual sponsor of the event.<br />
AI in AOI<br />
The most important driver of AI technologies in<br />
electronics production is in the field of automated<br />
optical inspection (AOI). Repetition-based learning<br />
algorithms—systems have been in the process of replacing<br />
conventional IT for over a decade. ”Since the<br />
Source: Messe Muenchen<br />
frequency of errors in electronics production is manageable,<br />
engineers have to create ‘artificial’ error<br />
patterns using image processing in order to achieve a<br />
more relevant learning sample for the AI and create<br />
an even greater learning effect,” explained Volker<br />
Pape, Chairman of the Board in the Productronics<br />
division of the VDMA, and co-founder of Viscom.<br />
Almost all automated inspections systems in electronics<br />
production are now smart factory ready.<br />
Leading providers of AOI in <strong>Europe</strong>, including Goepel,<br />
Koh Young, Saki, and Viscom – all of whom are exhibiting<br />
at Productronica 2023 – are actively transitioning<br />
to using AI in their systems.<br />
“Even without AI, two thirds of assemblies tested<br />
are classified as good,” Dr. Sebastian Mehl, whose<br />
task at Siemens is to integrate mature and working<br />
AI applications into production environments in<br />
electronics production, explained. “Of the around<br />
30% that don’t pass the first time, only the smallest<br />
portion actually have an error. If humans undertook<br />
inspection for this number of false calls in the second<br />
pass, it would entail significant additional inspection<br />
effort. Moreover, there would be a high risk<br />
of several of the actual errors being overlooked.<br />
”In SMT production lines at Siemens, the number<br />
of false calls has been halved, and the first pass rate<br />
increased by 15% with the aid of AI. The additional<br />
inspection effort that is no longer required can be<br />
tangibly measured in annual six-digit savings.”<br />
Power electronics<br />
Analysts from the Yole Group expect the global<br />
power electronics market to grow from USD 20.9 billion<br />
(2022) to USD 33.3 billion by 2028 at a compound<br />
annual growth rate (CAGR) of 8.1 percent.<br />
Governmental regulations, the expansion of renewable<br />
energies and the demand for energy-efficient<br />
solutions are further driving the trend.<br />
According to Spherical Insights, the industrial sector<br />
currently holds a 24 percent share of the market<br />
as power electronics devices and systems become<br />
ever more widespread in motor drives, power<br />
supplies, robotics and process control. The growth of<br />
14 <strong>EPP</strong> <strong>Europe</strong> » 11 | 2023
industrial automation is also an important driver in<br />
the expansion of this market.<br />
Productronica exhibitors Rohde&Schwarz, Viscom,<br />
Löhnert, CRS Prüftechnik and SPEA will exhibit<br />
relevant solutions in this area.<br />
Silicon carbide & gallium nitride<br />
The competitive cost/performance ratio of silicon<br />
makes it still the most widespread semiconductor<br />
material but it reaches its limits when higher operating<br />
frequencies and breakdown voltages are<br />
required. Because of this, components made of gallium<br />
nitride (GaN) and silicon carbide (SiC) are increasingly<br />
entering the field. Inverters based on wide<br />
bandgap semiconductors enable faster and lowerloss<br />
switching with significantly higher efficiencies.<br />
They are able to switch to higher voltages at higher<br />
frequencies—with less cooling required. Shorter<br />
switching times significantly reduce energy losses at<br />
are also able to tolerate more compact passive components<br />
such as inductors or capacitors.<br />
Because of the lengthier and more complex manufacturing<br />
processes required, chips made from silicon<br />
carbide and gallium nitride are significantly more expensive<br />
than their silicon counterparts. However,<br />
manufacturers expect to reduce costs by switching<br />
to 300-mm wafer technology.<br />
SiC in automotive applications<br />
Silicon carbide offers significant advantages in<br />
power electronics applications in electric vehicles.<br />
More efficient and more compact drive and charging<br />
systems can increase a vehicle’s range and shorten<br />
charging time. In Hall B2, Stand 448, VDMA co-exhibitor<br />
Breuer-Motoren will present a SiC inverter<br />
power amplifier developed as part of the research<br />
project ”SiC-Mobil—SiC frequency converter for<br />
electromobility” as a test platform for investigating<br />
the reliability, service life, EMC and efficiency of<br />
fast-switching SiC power semiconductors.<br />

AT A GLANCE<br />
Here, Koh Young explains how<br />
real-time inspection and process<br />
control can prevent defects<br />
at the source, and highlights<br />
the importance of integrating<br />
IPC communication<br />
standards into its tools.<br />
In the relentless pursuit of manufacturing excellence,<br />
the advent of the smart factory has brought<br />
about a new era of innovation and efficiency. At the<br />
forefront of this transformation is Koh Young Technology,<br />
an industry leader driving the evolution of<br />
inspection-based process control tools to reshape<br />
modern electronics manufacturing.<br />
The smart factory: a paradigm shift<br />
Gone are the days of inefficient, error-prone<br />
manufacturing. The smart factory has emerged as a<br />
catalyst for change, powered by advanced technologies<br />
like IoT (Internet of Things), AI (artificial intelligence),<br />
and machine learning. At the heart of this<br />
transformation lies a synergy between advanced inspection<br />
systems and process control tools. These<br />
work together to ensure quality is maintained at<br />
every stage of production. We recognise this transformative<br />
potential and have harnessed it to lead the<br />
charge towards a smart factory.<br />
With unwavering dedication to<br />
accuracy, quality, and efficiency,<br />
Koh Young is driving a new era of<br />
production in which inspection and<br />
process control seamlessly merge<br />
to create optimized processes for<br />
electronics manufacturers of all<br />
shapes and sizes.<br />
The convergence of inspection and<br />
process control<br />
At Koh Young, we envision a world in which inspection<br />
is not just a post-production ritual but an<br />
integral part of the production process itself.<br />
Traditional methods of quality control often lead to<br />
the identification of defects after products have already<br />
been manufactured, resulting in increased<br />
costs and wastage. Our approach is different. We advocate<br />
real-time inspection and process control that<br />
identifies issues at the source, preventing potential<br />
defects.<br />

COVER STORY » INSPECTION & PROCESS CONTROL<br />
Using advanced 3D measurement-based inspection<br />
and AI algorithms, our machines accurately<br />
evaluate product quality. This real-time data integrates<br />
seamlessly into process control tools that dynamically<br />
adjust parameters to maintain optimal<br />
production conditions. This holistic approach ensures<br />
consistent quality, reduces rework, and enhances<br />
production efficiency.<br />
The power of data: from insights to<br />
action<br />
In the smart factory ecosystem, data fuels continuous<br />
improvement. Inspection-based process<br />
control tools generate valuable data, offering<br />
insights into trends, patterns, and potential improvements.<br />
By analysing this data, manufacturers can<br />
identify bottlenecks, fine tune processes, and even<br />
predict maintenance needs, all while maintaining the<br />
highest possible quality standards.<br />
“We envision a world in which inspection<br />
is not just a post-production ritual<br />
but an integral part of the production<br />
process itself.”<br />
Our tools enable predictive analytics that help<br />
manufacturers anticipate deviations from optimal<br />
conditions and take corrective action proactively.<br />

serve as a bridge, empowering the workforce by providing<br />
real time guidance and insights. Operators are<br />
equipped with a digital companion that guides them<br />
through processes, alerts them to potential issues,<br />
and fosters a deeper understanding of the production<br />
line. This symbiotic relationship between technology<br />
and human expertise is the cornerstone of<br />
the smart factory.<br />
Revolutionizing control: KPO<br />
At the epicentre of our commitment to manufacturing<br />
excellence lies the groundbreaking Process<br />
Optimizer (KPO). This innovation epitomizes the<br />
company‘s mission to synergize inspection and process<br />
control: a single tool designed to boost efficiency<br />
and precision.<br />
KPO is the keystone that integrates our inspection<br />
systems with real-time process control. Through an<br />
intuitive interface, operators gain access to a dashboard<br />
of vital production insights - ranging from the<br />
minutiae of individual measurements to macroscopic<br />
trends that influence overall product quality. KPO is<br />
more than a data aggregator, however. It is a decision-making<br />
engine that gives operators the knowledge<br />
to tweak production parameters, optimise<br />
workflows, and eliminate defects before they<br />
happen.<br />
Leveraging AI algorithms that learn and adapt,<br />
KPO evolves in tandem with the production line. It<br />
assesses production data to predict potential deviations,<br />
and offers recommendations to maintain<br />
peak efficiency and quality. In enabling operators to<br />
make informed decisions swiftly and confidently,<br />
KPO bridges the gap between experience and automation,<br />
creating a holistic production environment<br />
where expertise is enhanced – not replaced.<br />
Beyond machine-to-machine<br />
connectivity<br />
As manufacturing evolves towards Industry 4.0, inspection-based<br />
process control tools become even<br />
more critical. Koh Young’s innovative approach has<br />
already set the stage to revolutionize the manufacturing<br />
process. Nonetheless, the journey towards a<br />
fully realized smart factory involves a synergy of<br />
standards that facilitate communication across production<br />

IPC CFX: enabling seamless<br />
communication<br />
IPC CFX (Connected Factory Exchange) is an open,<br />
neutral, and secure standard designed to enable real<br />
time, bidirectional communication between machines,<br />
devices, and enterprise systems in a factory.<br />
By integrating IPC CFX into the smart factory framework,<br />
manufacturers can benefit from: enhanced visibility<br />
of production processes; faster decision-making,<br />
and better overall equipment effectiveness.<br />
Our inspection-based process control tools,<br />
coupled with IPC CFX, support the exchange of<br />
critical data across the manufacturing floor. These<br />
inspection systems generate real-time insights,<br />
which are seamlessly communicated through the IPC<br />
CFX standard to other machinery and systems. This<br />
exchange of data ensures that the entire production<br />
line operates in harmony. This, in turn, enables rapid<br />
responses to deviations, which reduces downtime,<br />
and optimizes production quality.<br />
IPC HERMES:<br />
facilitating intelligent logistics<br />
IPC HERMES is another communication standard<br />
that complements an Industry 4.0 transformation.<br />
Focused on streamlining communication between<br />
different machines in the electronics assembly line,<br />
IPC HERMES ensures an efficient flow of production<br />
materials and products, allowing for reduced lead<br />
times, enhanced traceability, and minimal errors.<br />
When integrated with our inspection-based process<br />
control tools, IPC HERMES facilitates dynamic<br />
adjustments to the assembly process based on inspection<br />
results. For instance, if a Koh Young SPI or<br />
AOI detects a defect, the information can be communicated<br />
through IPC HERMES to other machines<br />
downstream, triggering immediate adjustments to<br />
rectify the issue. This level of intelligent communication<br />
results in a production line that runs with<br />
agility and adaptability, minimizing waste and maximizing<br />
efficiency.<br />

Thermal management using insulated metal substrates<br />
Applying IMSs in lighting and<br />
power conversion<br />
The first article in this two-part series described the composition, principles, and thermal<br />
properties of insulated metal substrates (IMSs). This article looks at use cases in power<br />
conversion and lighting, the effects of high-emissivity coating, and often overlooked design<br />
considerations.<br />
» Chris Hanson, Global Head IMS Technology, Ventec International Group<br />
LED lighting dominates new designs for building<br />
and automotive applications. However, excessive<br />
operating temperature can change the chromaticity<br />
of the emitted light, reduce lifetime, and may<br />
destroy the LED. Proper thermal management must<br />
therefore restrict the temperature to below the safe<br />
maximum for a semiconductor device.<br />
Applications<br />
Among automotive lighting applications, matrix<br />
headlamps contain multiple emitters closely spaced<br />
on a single substrate to provide a high lumen output.<br />
Typically, a high-conductivity IMS featuring either an<br />
aluminium or copper baseplate is used. Non-reinforced<br />
dielectric, usually about 0.05mm-thick, minimizes<br />
CTE-related stresses between an aluminium<br />
baseplate and copper foil. In very high-power applications,<br />
a copper baseplate can avoid excessive<br />
stress due to CTE mismatch.<br />
Spotlights or daytime running lamps (DRLs) often<br />
comprise multiple small boards, each containing two or<br />
three emitters. An IMS aluminium baseplate and<br />
0.075–0.010 mm dielectric, resulting in thermal conductivity<br />
of 2–3 W/m.K is commonly used in these cases.<br />
Turn signals are often subject to extreme constraints<br />
in size and shape because of their placement<br />
on a vehicle’s extremities. A three-emitter unit<br />
would need to dissipate about 7 watts, which can be<br />
achieved using an IMS with 0.05–0.075 mm dielectric<br />
thickness and thermal conductivity of about 3<br />
W/m.K. Attaching the IMS to the vehicle chassis<br />
further enhances thermal dissipation.<br />
General lighting and power<br />
conversion<br />
Applications such as street lighting require powerful,<br />
reliable illumination with extended replacement<br />
intervals. An IMS with thermal conductivity of about<br />
3 W/m.K and a 0.075–0.10 mm dielectric effectively<br />
limits the LED temperature and preserves chromaticity,<br />
while allowing a high drive current.<br />
In very high-power applications such as industrial<br />
welders, where the torch can draw 50 A to 400 A or<br />
more from chopper or inverter circuits, a heavy-duty<br />
copper foil, high-voltage dielectric, and a high-conductivity<br />
baseplate are combined with heatsinks and<br />
oil cooling.<br />
High-power air-conditioners commonly use IMSs<br />
22 <strong>EPP</strong> <strong>Europe</strong> » 11 | 2023
to connect power inverters and triac circuits to the<br />
air-cooled chassis or heatsink. An aluminium baseplate<br />
and conductivity of up to 10 W/m.K are typical.<br />
Automotive electrification<br />
In addition to LED lighting, electric power steering<br />
(EPS) and electrical pumps and fans are replacing<br />
traditional mechanical or hydraulic units in today’s<br />
cars. Additionally, electric and hybrid vehicles contain<br />
AC/DC converters for regenerative braking and<br />
on-board chargin; DC/DC converters for dual-battery<br />
management and bi-directional power supply; highvoltage<br />
batteries, and traction motors. The power<br />
semiconductors in these systems can dissipate total<br />
power from several hundred watts up to tens of kilowatts.<br />
Targets for module size and reliability can be met<br />
cost-effectively using a high-performing IMS with<br />
thermal conductivity of 3–4.2 W/m.K and<br />
0.10–0.15 mm dielectric. Power transistors can be<br />
soldered to the IMS circuit layer as bare die. The<br />
baseplate is often integrated with a cast metal chassis<br />
or may be attached to a liquid-cooled heatsink.<br />

thinner, heatsink-free assembly. The required thermal<br />
dissipation of 5 W was originally achieved using<br />
20 mm x 20 mm FR-4 PCB with a 35mm heatsink;<br />
calculated using an online heatsink design tool.<br />
Ventec has created a similar software application<br />
to calculate IMS parameters. This predicts that a<br />
100 mm x 100 mm Ventec VT-4B5 IMS with standard<br />
brushed aluminium finish could dissipate 5 W without<br />
needing a heatsink (thus also eliminating the<br />
need for a thermal interface material). Recalculating<br />
with the added effect of a ER1 high-emissivity coating<br />
shows the IMS size can be reduced to 70 mm x 70 mm.<br />
Potentially overlooked…<br />
Although thermal conductivity, cost, and material<br />
thickness are the dominant selection criteria when<br />
choosing an IMS, there are several other factors to<br />
consider.<br />
When choosing the dielectric, ensure that the<br />

Резюме<br />
В первой статье этой серии из двух частей<br />
описывается состав, принцип и термические свойства<br />
изолированных металлических подложек. В этой<br />
статье рассматриваются варианты использования в<br />
сфере преобразования энергии и освещения,<br />
влияние покрытий с высокой эмиссионной<br />
способностью и часто упускаемые из виду<br />
конструктивные вопросы.<br />
breakdown voltage and thickness provide sufficient<br />
electrical insulation.<br />
To decide the copper-foil weight, based on the application<br />
operating current, note that the IMS reduces<br />
I2R-induced temperature rise, thereby increasing<br />
the effective current-carrying capacity.<br />
Consider creepage distance (also known as leakage<br />
distance) when designing for power applications.<br />
Creepage is dependent on the insulator’s comparative<br />
tracking index (CTI). Datasheets often give a<br />
CTI of 600 V for IMS materials, whereas the CTI for<br />
conventional FR4 is usually 175 V–249 V.<br />
When choosing the base metal layer, consider the<br />
coefficient of thermal expansion (CTE) in addition to<br />
cost, rigidity, and weight - particularly in applications<br />
that experience intensive thermal cycling.<br />
Selecting a value that closely matches component<br />
and circuit-layer expansion can minimise solder joint<br />
fatigue. Large devices, extreme temperature differentials,<br />
and lead-free minimum solder thicknesses<br />
can all contribute to increased cyclic shear stress on<br />
solder joints.<br />
Also consider the base material’s suitability for<br />
machining and post-forming operations.<br />
Test methodologies<br />
When characterising the thermal conductivity of<br />
their IMS products, manufacturers may choose from<br />
several standardised test methodologies. These include<br />
ASTM E1461 which is a contactless high-temperature<br />
test. Another is ISO 22007–2, performed<br />
using a 3mm-thick disc of the test material. ASTM<br />
D5470 also uses a disc-shaped sample of the test<br />
material and establishes a temperature gradient that<br />
can be measured in the steady state. In addition,<br />
there are various theoretical mathematical models<br />
such as the Bruggeman model.<br />
All approaches have intrinsic inaccuracies, and all<br />
typically give different answers with the same material<br />
under the same conditions. Moreover, manufacturers’<br />
datasheets do not always state the method<br />
used, which can prevent designers from making accurate<br />
comparisons. Independent testing is therefore<br />
recommended to predict performance accurately in<br />
the intended application.<br />
Conclusion<br />
IMSs can provide accurately controlled thermal<br />
management in systems that dissipate significant<br />
quantities of self-generated heat. There are many<br />
parameters that can be optimised, allowing for an<br />
effective, compact, and reliable solution.<br />

Removal of residual solder in rework processes<br />
Kurtz Ersa introduces auto scavenger module for rework system<br />
Kurtz Ersa has unveiled the Auto Scavenger Module,<br />
an extension for the Ersa HR 600 XL rework platform.<br />
Designed to enhance the efficiency and effectiveness<br />
of non-contact removal of residual solder from circuit<br />
boards, this module represents a significant advancement<br />
in rework technology.<br />
With just three simple clicks, users can define the<br />
specific area on the assembly where residual solder<br />
needs to be removed after desoldering a component.<br />
The module then automatically identifies the required<br />
tracks and initiates the cleaning process promptly,<br />
while ensuring the board remains preheated.<br />
Featuring cleaning speeds ranging from 1 mm/s to<br />
3 mm/s, the module ensures efficient and thorough removal<br />
of residual solder from large electronic assemblies.<br />
Moreover, users have the flexibility to finetune<br />
the cleaning performance by adjusting parameters<br />
such as nitrogen temperature and track speed. Individual<br />
profiles can be saved for each assembly, enabling a<br />
customized and optimized cleaning process.<br />
The module operates with a constant base temperature<br />
for the entire assembly. The solder to be removed<br />
is heated on the board surface using an<br />
N2-fed hot gas nozzle and then extracted via a vacuum<br />
nozzle. Importantly, the automatic height control<br />
feature ensures that the assembly remains untouched<br />
physically throughout the process. Additionally,<br />
users can mark ‘keep out areas’ directly in the<br />
live image, designating specific regions where suction<br />
is not required. Once the solder removal is com-<br />
plete, the assembly is efficiently cooled down and<br />
ready for the seamless reinstallation of a component.<br />
“The introduction of the Auto Scavenger Module represents<br />
another step forward in rework technology,”<br />
said Todd DeZwarte, Director of Sales – North America,<br />
Rework & Inspection at Ersa. “We are excited to<br />
offer our customers a solution that not only enhances<br />
the cleaning performance of the HR 600 XL<br />
rework system but also provides the flexibility and<br />
precision required for diverse assembly requirements.<br />
This module enables efficient and reliable removal of<br />
residual solder, contributing to improved productivity<br />
and high-quality results.”<br />
The Auto Scavenger Module is available as an optional<br />
feature for the Ersa HR 600 XL rework system.<br />

Moving beyond manual ID methods<br />
Laser labelling in electronics<br />
manufacturing<br />
With many customers concerned that manual product labelling, used to identify<br />
and monitor parts, is unable to meet the stringent demands of modern electronics<br />
manufacturing, could laser labelling be the answer? Joe Booth, CEO of Altus<br />
Group, weighs up the pros and cons.<br />

The UK is home to a substantial portion of the<br />
world‘s contract electronics manufacturing<br />
(CEM) sector which produces high volumes of critical<br />
high-value electronics like medical devices, automotive<br />
and telecoms equipment. This complex, high-mix<br />
production landscape has driven an increased emphasis<br />
on quality control and traceability – both essential<br />
to manufacturers embracing Industry 4.0<br />
practices. It has also led to concerns about product<br />
identification processes, with many finding manual<br />
product labelling for the identification and monitoring<br />
of parts inadequate for today’s stringent demands.<br />
Moreover, labour shortages in the UK mean<br />
that CEMs are now looking to automate repetitive,<br />
manual processes. To address these issues, a growing<br />
number of manufacturers are transitioning to automated<br />
laser marking systems.<br />
Manual labelling - pros and cons<br />
Manual labelling was previously been seen as a<br />
simple and inexpensive option for basic product<br />
identification. Workers quickly applied pre-printed<br />
stickers by hand or added markings to PCBAs with<br />
stencils or ink pens to designate logos, serial<br />
numbers, and barcodes. This made manual labelling<br />
an appealing starting point when production volumes<br />
were smaller and products less complex. As<br />
manufacturing has exponentially increased, products<br />
have become more sophisticated, and technical<br />
specifications have grown more exacting, however,<br />
manual labelling has proved limited in meeting the<br />
complex requirements of cutting-edge electronics<br />
manufacturing.<br />
Undoubtedly manual labelling remains a good option<br />
for prototyping and early development. The low<br />
cost and flexibility of a simple sticker means labels<br />
on prototypes can be applied and modified as designs<br />
evolve. This adaptability enables quick iteration<br />
without specialised equipment. In a high-volume<br />
production environment, however, there are several<br />
important drawbacks to manual labelling methods,<br />
outlined below.<br />
26 <strong>EPP</strong> <strong>Europe</strong> » 11 | 2023
Human error and inconsistency<br />
Manual label application is subject to human error.<br />
Even the most skilled operator will make the occasional<br />
mistake – and the probability of this happening<br />
increases as production runs get longer. Different<br />
operators also apply labels differently. Inconsistencies<br />
and inaccuracies in component identification<br />
can lead to defective products, recalls, and traceability<br />
problems.<br />
Time-consuming<br />
Manually adding individual labels onto components<br />
is a slow process, especially with small electronic<br />
components. Even for an experienced worker,<br />
handling and positioning each tiny label is time consuming.<br />
The more labels required per product, the<br />
greater the time involved. This process becomes<br />
highly labour intensive and can cause a bottleneck in<br />
production flows, which significantly decreases<br />
manufacturing throughput and efficiency.<br />
Source: Altus<br />
Lack of adaptability<br />
Pre-printed labels used in manual labelling processes<br />
offer minimal flexibility when design changes<br />
are required. Companies using manual labels must<br />
discard obsolete label stocks and order new preprinted<br />
labels whenever they want to adjust label<br />
content or position. This wastes inventory and<br />
requires production downtime during changeovers.<br />
With pre-printed labels, unique serial numbers cannot<br />
be generated, nor is customisation, or variable<br />
data like date codes possible.<br />

Questionable reliability<br />
The adhesives used in manual stick-on labels can<br />
fail over time if exposed to humidity, high temperatures,<br />
abrasion, or chemicals. Labels can peel, fall off,<br />
become illegible or disappear completely – resulting<br />
in products with missing or incorrect identification<br />
markers. This makes ongoing traceability and warranty<br />
tracking difficult.<br />
Restricted options<br />
Manual labels can only be applied on accessible<br />
surfaces with enough area for adhesion. Irregular<br />
shapes, smaller sizes, and hidden areas restrict where<br />
labels can be placed. Only certain materials can be<br />
labelled, and these must meet size requirements for<br />
human handling. All these constraints limit options<br />
for product design and labelling location.<br />
Additionally, manual labelling cannot fulfil the obligations<br />
for permanent marks mandated by certain<br />
regulatory requirements like unique device identification<br />
(UDI). Overall, the limitations and disadvantages<br />
inherent to manual labelling make it unsustainable<br />
for high-quality electronics production.<br />
Is laser labelling the answer?<br />
Automated and precise, modern laser marking systems<br />
bypass the limitations of manual labelling by<br />
offering permanent marking capabilities. Although<br />
manufacturers may be put off by the initial outlay to<br />
purchase the equipment, laser marking has numerous<br />
advantages that far outweigh the investment<br />
cost. Such systems have become integral to production<br />
lines, prompting many CEMs to opt for laser<br />
marking technology.<br />
Range of labels with a range of sizes and information attributed<br />
Source: Altus<br />
Permanent marks<br />
Lasers create marks by altering the surface structure<br />
of materials through ablation, oxidation, melting<br />
or other photochemical processes. This means labels<br />
become integral, permanent parts of the product<br />
and are not just stuck on. Laser marked identification<br />
withstands wear, abrasion, temperature extremes<br />
and chemical exposure. Electronics OEMs can trace<br />
labelled products across their entire lifecycle.<br />
Precision and legibility<br />
Lasers can etch intricate details and small font<br />
sizes down to micron levels. Complex machine-readable<br />
codes like barcodes can be inscribed with perfect<br />
precision and accuracy. This prevents errors in<br />
component identification – especially critical for<br />
complex miniature electronics parts. Laser labelling<br />
is effective on unusual shapes and designs, including<br />
on curved, angled or hidden surfaces not reachable<br />
using manual methods.<br />
Hands-free<br />
Laser marking is a non-contact process. It does not<br />
require physical contact with the PCB surface, unlike<br />
ink printing or mechanical engraving methods. The<br />
laser imprints by directing focused light energy onto<br />
a material to alter its structure without touching it.<br />
This non-contact process eliminates any risk of damage,<br />
distortion, or stress to delicate electronic<br />
components during marking. This enables safe, clean,<br />
and damage-free identification of even the most<br />
sensitive, densely-packed PCB designs. It can also be<br />
applied on various surfaces, from metals and ceramics<br />
to laminates and plastics, making it ideal for<br />
modern high-mix electronic components.<br />
28 <strong>EPP</strong> <strong>Europe</strong> » 11 | 2023
Easy to integrate<br />
Laser marking methods seamlessly integrate with<br />
fully automated production lines and material handling<br />
systems. Parts can be precision marked quickly<br />
with no manual intervention. Programmable laser<br />
systems also enable rapid changeovers between label<br />
formats and data variables. This allows for highthroughput<br />
production runs without delays.<br />
Source: Altus<br />
Adaptable<br />
Laser systems excel at on-demand marking of labels<br />
with variable information like dates, times, and<br />
serial numbers. Programming is fast and flexible –<br />
allowing for quick customer-specific customisation.<br />
Regulatory compliant<br />
Stringent government traceability regulations like<br />
UDI require permanent product labels that remain<br />
intact over long periods and harsh conditions. Laser<br />
marking satisfies labelling permanence regulations<br />
that manual methods cannot.<br />
The clear choice for the future?<br />
After considering the advantages and disadvantages<br />
of manual and laser labelling, it is evident that<br />
laser technology is the best option for the electronics<br />
manufacturing of today. The drawbacks and bottlenecks<br />
inherent to manual methods hinder quality,<br />
throughput, and responsiveness. Laser labelling addresses<br />
these shortfalls and facilitates state-of-theart<br />
production.<br />
Laser systems meet the rigorous demands of highprecision<br />
Industry 4.0 electronics production, enabling<br />
immediate and flexible product identification,<br />
intricate coding, automated workflows, and label<br />
permanence. As electronics manufacturing processes<br />
evolve and smart factories and data-driven production<br />
strategies take over, laser labelling can fit in<br />
seamlessly. Laser systems interface directly with central<br />
automation controls, production databases, enterprise<br />
resource planning systems and machine<br />
learning platforms, making laser-marked labels essential<br />
components of advanced PCBA manufacturing<br />
practices.<br />

Transforming labour shortages into business advantages<br />
Addressing labour challenges<br />
in electronics manufacturing<br />
In 2014, a study conducted by the Boston Consulting Group predicted that many countries<br />
would experience labour shortages in the 2020s and “a massive shortfall” by 2030. This<br />
is proving correct. In an age of supply chain disruptions and generational workforce<br />
evolution, manufacturers are struggling to find qualified employees. Increasing digitalization<br />
may be the key to finding and retaining talent.<br />
» Oren Manor and Markus Sauter, Siemens Digital Industries Software<br />
Staffing and resource constraints<br />
According to Ranstad, an aging global population is a<br />
significant factor in the current labour shortage. By<br />
2030, 16 percent of the world population will be 65 and<br />
over, and, by 2050, this proportion will have doubled.<br />
Finding skilled replacements is an urgent matter.<br />
Manufacturing today’s complex products demands<br />
a higher level of skilled workers. Adaptability and<br />
flexibility are increasingly important as shorter lead<br />
times create the need for more versatile workers who<br />
can perform multiple functions.<br />
The convergence of<br />
various major global<br />
trends is increasing the<br />
complexity of electronics<br />
manufacturing<br />
and impacting the<br />
workforce<br />
Even before Covid-19, staffing was a challenge.<br />
Then, with the arrival of the great resignation,<br />
the challenge became even more acute. Today, the<br />
convergence of various global events and industry<br />
trends is increasing the complexity of electronics<br />
manufacturing, and this is having a knock-on effect<br />
on recruitment. Understanding how each factor impacts<br />
the workforce is vital to finding effective solutions<br />
to labour shortages, so here’s a short overview.<br />
Supply and component shortages<br />
Global events such as the pandemic, the Russian<br />
war with Ukraine, international trade tensions, global<br />
shipping bottlenecks and surges in demand for<br />
materials all contribute to supply chain volatility.<br />
This impacts every sector from metals to chemicals,<br />
including, of course, manufactured components, as<br />
well as semiconductors and related devices. This<br />
level of unpredictability directly affects manufacturing<br />
workflows.<br />
Source: Siemens<br />
Sustainability<br />
The desire to create a more sustainable work environment<br />
that lowers ecological impact, reduces<br />
energy usage, reduces waste and improves operational<br />
excellence is transforming the workplace into<br />
a healthier space for employees.<br />
Fortunately, solutions to these issues are beginning<br />
to emerge. According to Ranstad’s 2022 study, “Why<br />
is there a global labor shortage?”, it is vital that employers<br />
understand the candidate-driven employment<br />
market, and the factors valued most-highly by<br />
workers. These are competitive salaries (58 %), job<br />
security (56 %) and work environment (55 %). The<br />
biggest opportunity for employers to attract skilled<br />
workers is to address the working environment. And<br />
digitalization could be the key to success in this area.<br />
Finding and retaining talent<br />
If you want to land talented individuals in today’s<br />
competitive hiring environment, it is essential to<br />
think outside the box. Increased digitalization can<br />
help upgrade production environments and elevate<br />
worker experience, paving the way for new recruitment<br />
opportunities.<br />
Digitalization can help make the working environment<br />
a more enjoyable place for younger workers.<br />

Ensuring consistency and traceability of product<br />
and process for all manufacturing strategies<br />
With increased automation, skilled personnel will have<br />
greater opportunities to expand their skillsets and become<br />
upwardly mobile as they learn to perform a variety<br />
of jobs across various manufacturing processes.<br />
Digitalized planning and advanced automation enable<br />
a flexible, optimized workflow. Options such as offering<br />
a four-day work week to recruits who would<br />
value this arrangement could give your company a<br />
competitive edge. Another option is to prioritize the<br />
recruitment of young talent. Young people can be<br />
brought in at a lower level and gradually move up<br />
into positions of increasing responsibility as they<br />
learn the manufacturing system and acquire a variety<br />
of skills. Surprisingly, only 38 percent of organizations<br />
currently make it a priority to recruit young<br />
talent, according to the Ranstad study.<br />
Digitalization can facilitate options for remote<br />
working including remote roles, remote monitoring<br />
and job variations. These options can help companies<br />
manage critical processes and still provide workers<br />
with flexibility at work and at home, making jobs<br />
more attractive to a wider range of people.<br />
Recruiting talent for specific skill sets from abroad,<br />
from South America, Africa and Asia, for instance, becomes<br />
easier if you offer remote working. This means<br />
new hires do not have to physically relocate across<br />
borders to your plant location, avoiding extra expense.<br />
The digitalization difference<br />
“In a world where more than half the population is<br />
under 25, businesses cannot afford to ignore digital<br />
transformation,” McKinsey & Company recently observed.<br />
Digital transformation is one variable that<br />
can enable manufacturers to significantly improve<br />
performance, both on the shop floor and in terms of<br />
the quality of their workforce. A talented workforce<br />
that spans generations has the potential to take a<br />
company’s performance to an entirely new level.<br />
Young talent is attracted to digital transformation<br />
and digital technology. Unlike older workers, many<br />
younger workers have experienced digital classrooms<br />
firsthand. They are better prepared to adapt to the<br />

Top tips<br />
Keep the following in mind when designing your<br />
recruitment strategy for a revitalized workforce:<br />
• Digitalization is attractive to skilled workers and younger<br />
talent<br />
• Streamlined engineering and manufacturing processes<br />
make your workplace and your job opportunities more<br />
appealing<br />
• Seamless data flow from engineering to execution<br />
increases productivity and reduces stress<br />
• Using digitalization supports a diversity of tasks,<br />
minimizes monotonous work, and allows easy job rotation<br />
using guided and automated operations<br />
• Leveraging digitalization helps create a more productive<br />
and profitable company that can offer employees more<br />
advancement opportunities<br />
• Digitalization enables opportunities for automation<br />
and artificial intelligence (AI) to create a working<br />
environment that supports advanced skills<br />
• Adopting digitalization enables recruitment of a more<br />
talented workforce with the ability to improve company<br />
performance<br />
• Remote work options enable you to tap new pools of talent<br />
When recruiting today, it is important to develop an<br />
appealing image. Talented workers are drawn to clean<br />
workplaces that offer career advancement in high<br />
tech fields, so we should design our workplaces and<br />
our recruiting strategies to promote these benefits.<br />
Siemens digitalization solutions<br />
Digital solutions such as a manufacturing execution<br />
system (MES) can play a critical role in addressing<br />
labour challenges. Digitalization can increase<br />
your appeal as a company by providing stress-relieving<br />
solutions for workers in the fields of both IT and<br />
production.<br />
Problems with integrating IT and operating technology<br />
(OT) often lead to extra work and undue<br />
stress on the workforce. This is exacerbated when<br />
multiple legacy information systems are unconnected,<br />
lack a common data platform or language,<br />
and cannot work together, resulting in an enormous<br />
workload. Fragmented systems need to be digitally<br />
transformed so they work more efficiently together,<br />
and the effort needed to sustain them is reduced.<br />
Fortunately, this fragmentation and the stress can be<br />
alleviated by adopting an end-to-end digital solution<br />
that provides a single digital thread with connected<br />
systems. This enables efficient, unified operation<br />
from product design to manufacturing execution.<br />
The Siemens Xcelerator business platform, comprising<br />
software, hardware and services, provides an<br />
integrated digital thread spanning from design to<br />
production engineering, streamlining processes<br />
through one end-to-end digital solution. The MES<br />
solution also includes a manufacturing operations<br />
management (MOM) system to address labour-related<br />
challenges. When we start breaking down disconnected<br />
silos this transformation can begin.<br />
The MOM system combines all machine programming<br />
into a single platform, and better defines workflows,<br />
resulting in better quality, and saving time and<br />
stress for workers. It consolidates production processes<br />
to optimise MESs, quality management, and<br />
improve planning and scheduling. It also reduces the<br />
workload so staff can focus instead on value-added<br />
tasks. MOM advantages include:<br />
• Providing guidance in setup and execution tasks<br />
• Prompting workers for required actions<br />
• Avoiding errors and rework<br />
• Supplying automated control and traceability of<br />
tasks, process, material and tools<br />
• Using maintenance management to minimize machine<br />
breakdowns<br />
• Improving operator efficiency by allowing them to<br />
run multiple machines and lines<br />

Changing perceptions<br />
The notion of manufacturing as a gritty working environment<br />
is an image that needs to be updated. By<br />
increasing their focus on digitalization, manufacturers<br />
can change these outdated perceptions, and win new<br />
recruits. Digitalization can streamline engineering and<br />
production processes to create a lean, modern, and<br />
productive working environment. These changes elevate<br />
quality of life for the workforce and enable companies<br />
to be more competitive. With digitalization<br />
underway, you are ready to recruit a more talented<br />
workforce. And with an improved workforce, company<br />
performance can reach a whole new level.<br />

Experiment & analysis in QFN assemblies<br />
Minimizing voiding in SMT<br />
assembly of BTCs<br />
Voiding in BTCs and, more specifically, QFNs, is arguably the most critical issue in<br />
electronic assembly today. In response to this concern, Indium Corporation and<br />
BTU International developed and executed a series of investigations to understand<br />
quantitatively the causes of voiding.<br />

X-ray images of voiding. These ‘lake voids’ with a greater than 40% area of voiding<br />
would likely cause reliability and performance problems for most QFNs<br />
Bottom terminated components (BTCs) are one of<br />
the most important components in electronics<br />
today. Their combination of small size, excellent<br />
electrical performance, and ability to transfer heat<br />
away from the integrated circuit (IC) has resulted in<br />
their becoming one of the most common packages<br />
with the highest growth rate. More than 15% of all<br />
electronic packages assembled are BTCs, with their<br />
numbers over 50 billion a year. One of the most common<br />
BTCs is the quad-flat pack no-leads (QFN). One<br />
of the primary attributes of QFNs is dissipating heat,<br />
therefore, any voiding of the solder connecting the<br />
thermal pad on the QFN to the printed wiring board<br />
(PWB) will degrade the intended performance of the<br />
QFN. This degraded thermal performance may result<br />
in reliability and operational issues. While degraded<br />
thermal performance may not be a critical issue for<br />
some consumer products, the rapid growth of automobile<br />
electronics and the emergence of 5G telecom<br />
equipment makes robust thermal performance of<br />
QFNs vital.<br />
Original investigation<br />
Generally, there are no industry standards as to<br />
what is an acceptable voiding level, although there is<br />
agreement that an average void area should be less<br />
than 50% with no single void above 40%. For thermal<br />
pads, a void area of less than 25% is preferred,<br />
and some automotive applications aim for an average<br />
void area of less than 10%. Clearly, all assemblers<br />
desire a minimum amount of voiding. However,<br />
the processes and materials available may limit<br />
this goal.<br />
Significantly reducing voiding is not necessarily a<br />
quick fix. Optimized solder paste and process conditions;<br />
control of the PWB and components; and a<br />
stencil printer, component placement equipment,<br />
and a reflow oven that are optimized to minimize<br />
voiding are needed.<br />
In our experiments, the PWB pad finish was ENTEK<br />
Plus CU-106A-HT OSP. We used laser cut, non-nanocoated<br />
steel stencils that were 0.004“ and 0.005“<br />
thick. We used a window pane stencil design in the<br />
PWB thermal pad area to allow volatiles to escape.<br />
The window pane squares were 0.088“ on each side.<br />
The squeegee printing speed was 100mm/s with a<br />
pressure of 6 kg. Printer separation speed was 5mm/s<br />
at a distance of 2mm. We performed a stencil wipe<br />
(W/D/V) before each board. The QFN we assembled<br />
had a square ground plane of 7.75mm (0.30“) per side.<br />
We performed reflow in air with Profile #1—a<br />
straight ramp profile (0.9˚C/second ±0.1˚C/second)<br />
and a peak temperature of 241˚C ±4˚C for most investigations.<br />
However, a second profile (Profile #2)<br />
with a peak temperature of 254˚C ±4˚C was also investigated<br />
to determine the effect of the reflow profile<br />
on voiding. A variety of solder pastes was used<br />
that had halogen-free and halogen-containing<br />
fluxes and different solder particles sizes (e.g., Type<br />
3, Type 4, Type 4.5, and Type 5).<br />

Many parameters affect voiding, as shown in this cause and effect diagram<br />
Reflow profile effects<br />
Profile #1 is a ramp-to-peak profile with a maximum<br />
temperature of approximately 240˚C ±4˚C.<br />
Profile #2 has a slight soak and a peak at 254˚C ±4˚C<br />
and has a slightly higher time above liquidus of 77<br />
seconds versus 70 seconds.Profile #2 had significantly<br />
better voiding results, yielding less than 8%<br />
void area versus 22% for Profile #1. Not only does<br />
Profile #2 significantly reduce the area of voiding,<br />
the scatter in the data is also greatly reduced.<br />
Our theory is that the hotter profile is more successful<br />
in driving out the volatiles than the cooler<br />
profiles. This concept is easy to understand when one<br />
considers that the vapour pressure of most solvents<br />
increases considerably at higher temperatures.<br />
this difference is significant. We believe that the<br />
5mil stencils exhibit less void area because the<br />
higher stand-off (0.005“ vs. 0.004“) allows for easier<br />
outgassing/venting of the solder paste flux volatiles.<br />
Stencil thickness<br />
We performed experiments in the conditions described<br />
with Profile #1 using two stencil thicknesses<br />
of 4mils and 5mils. A Tukey analysis indicated that<br />

Solder paste particle size<br />
We experimented with varying the solder paste<br />
particle size. The stencil thickness of 0.004“ and Profile<br />
#1 were used. The results of this indicate that<br />
there appears to be a slight reduction in void area<br />
with small solder paste particle sizes going from Type<br />
4 to 4.5 to 5; however, there is a significant increase<br />
in voiding area percent with Type 3 paste.<br />

Void percent area as a function of solder pastes. Note the<br />
significant difference between pastes, some as low as 5%<br />
voids and others around 45%<br />
Source: Indium Corporation<br />
Solder pastes<br />
We performed a final experiment in which we<br />
evaluated the effect of different solder paste flux vehicles<br />
on voiding. Three PCBs with 12 QFNs each<br />
were used for each solder paste, for a total of 36<br />
QFNs per paste. The results were striking, as seen in<br />
Figure 11. Some pastes produced about 5% voids,<br />
while others produced as much as 45%. These results<br />
were not only surprising, but also very encouraging.<br />
While the generation of voids is a complicated<br />
process with many variables, selecting the solder<br />
paste alone, with a standard assembly process can<br />
assure voiding area levels of less than 10%.<br />
Conclusions<br />
Although the factors that generate voids are many,<br />
by adopting a standard process as described, several<br />
parameters can be set to minimize voiding. The<br />
strongest determinant in the assembly process is to<br />
have a hotter peak temperature reflow profile. This<br />
factor alone reduced voiding area percent from an<br />
average of about 22% to less than 8%. Although<br />
finer solder particle size reduces solder voiding, the<br />
result was only statistically significant by going from<br />
Type 3 to Type 4 or finer. Type 3 pastes produced<br />
more than 10% more void area than Type 4 or finer.<br />
Using a stencil thickness of 5mils reduced voiding<br />
about 4% on average as compared to 4mil stencils.<br />
The greatest surprise, however, was how significant<br />
solder paste formulations were in reducing voiding.<br />
The better solder pastes significantly reduced voiding<br />
to less than 6% void area, whereas the worst paste<br />
produced greater than 45% voiding.<br />

The simulation results demonstrate that the<br />
maximum forces act upon different components<br />
and that there is no component for which a force resulting<br />
from all three directions of action must be<br />
taken into account as the greatest force.<br />
As the graphs opposite show, the maximum force<br />
in the X direction acts upon the smaller side surface<br />
of component 8. This force amounts to 45 µN. The<br />
maximum force in the Y direction (buoyancy force)<br />
acts upon the upper side of component 14 and<br />
amounts to 25 µN. The maximum force in the Z direction<br />
(graph on page 40) acts upon the larger side<br />
surface of component 25 and amounts to 52 µN. As<br />
the forces in the X and Z directions act upon component<br />
side surfaces of equal size, only the force in the<br />
Z direction will be regarded as the blowing force in<br />
the following, and the force in the Y direction will be<br />
regarded as the buoyancy force. The table below<br />
summarizes simulation results for the Y and Z directions.<br />
If flow velocity can be measured or determined<br />
numerically as described above, the force acting<br />
upon an object as a result of such flow can be calculated<br />
using the equation: F W<br />
=c 1 W<br />
/ 2<br />
pv 2 A<br />
The case in hand involves a rectangular body with<br />
a flow circulating around it. With a body of this type,<br />
resistance coefficient c W<br />
comprises 100% of the<br />
form resistance of the body and amounts to 1.1 [J.<br />
Zeitler & G. Simon, Physik für Techniker, 2016].<br />
Forces in the Z-direction can be calculated using<br />
density of air p (1.225kg/m³), the largest side surface<br />
area A of the component (1.53 x 10–6m²) and velocity<br />
values shown in the table below.<br />
Comparison of the forces reveals that, especially<br />
for higher velocities, the results of the two methods<br />
differ greatly. This can be attributed to finer flow<br />
state resolutions achieved with the CFD method, including<br />
detachment phenomena and so on.<br />

The holding forces for the three cases are calculated<br />
and compared with those numerically ascertained.<br />

classified as non-Newtonian and thixotropic fluids.<br />
Viscosity, and thus any response to a force, is dependent<br />
on the shear rate for this reason.<br />
In solder paste, stress is converted by means of<br />
shear into an elastic strain component and a plastic<br />
deformation component. After stressing has ended,<br />
the elastic strain component causes the solder paste<br />
to relax. The transition from the elastic to a plastic<br />
strain component is called the yield point [G. Diepstraten<br />
& D. Wu, ‘Estimating Stencil Life and Ideal<br />
Heating Profile of Solder Paste Using Advanced<br />
Thermo-Gravimetric Analysis’]. The yield point is<br />
temperature-dependent and should be determined at<br />
lower shear rates. The shows the yield points of various<br />
solder pastes as a function of temperature.<br />
A further solder paste characteristic is its so-called<br />
wet tackiness. The solder paste’s adhesive strength<br />
over a period of time ensures that components adhere<br />
to the printed paste not only immediately after<br />
assembly, but rather up through the soldering process<br />
as well. Wet tackiness counteracts component<br />
uplift due to the buoyancy force resulting from the<br />
flow of air or nitrogen.<br />

In the Y direction<br />
Buoyancy force in the Y direction at 100% fan<br />
power is 34.5 µN and is thus smaller than the weight<br />
force of the component which amounts to 44 µN.<br />
Taking the additional wet tackiness of the solder<br />
paste into account, the component cannot be displaced<br />
in this direction by the wind forces.<br />
In the Z direction<br />
As described in ‘Experimental Investigations’,<br />
blown off components (at 91% fan power and 180°<br />
C) in proximity to the pads exhibit failure due to<br />
shear stress. The diagram overleaf offers a schematic<br />
representation of shear stress on the solder paste<br />
layer as a result of lateral wind force.<br />
The fact that the shear stress on the solder paste<br />
does not occur abruptly, but gradually, must also be<br />
taken into account. The component moves into the<br />
flow of air at 16.7 mm/s, and blowing force increases<br />
as it gets closer to a nozzle. When this force exceeds<br />
the solder’s yield force, the component moves.<br />
Yield force F F<br />
with cross-sectional surface area A<br />
amounting to 1.35 x 10–7 m², which is equivalent to<br />
the contact surface of a lead, and a yield point σ F<br />
of<br />
273 N/m² at 23° C can be calculated with the<br />
formula: F F<br />
=2Aσ F<br />
and amounts to 73.7 µN. Blowing force in this direction<br />
is 71.3 µm and is smaller than the calculated<br />
yield force. It should also be noted that the solder<br />
paste is squeezed out around the lead after placement,<br />
increasing the effective surface area of the<br />
paste being sheared. If this arises, an area larger than<br />
just the connection area must be anticipated.<br />

3. With solder paste at 91% fan power and 180° C<br />
Component blow-off was observed at 180° C with<br />
91% fan power. As shown in the graph on page 41,<br />
the yield point of the solder paste decreases as a<br />
function of temperature. In zone 2, in which the<br />
knocked over components were discovered, the PCB<br />
had a temperature of 67° C. No results for the yield<br />
point of the solder paste are available for this temperature.<br />
For this reason, the yield point for solder<br />
paste 3 is extrapolated from the graph based on the<br />
assumption of a linear characteristic curve. The yield<br />
point is 162 N/m² and the resulting yield force is<br />
43.74 µN. This is smaller than the simulated force of<br />

deviation of these forces can be attributed to the<br />

определения влияния температуры<br />
подаваемого теплоносителя на отлетающие в<br />

Schematic representation of shear stress on the solder paste<br />
due to wind force<br />
Summary<br />
The investigation results presented here show that<br />
the SOD323 can be reliably processed by selecting<br />
appropriate solder and using the right oven settings.<br />
The default setting, i.e. 73% fan power, provides a<br />
sufficient safety margin relative to determined limit<br />
loads at 91% fan power. For some PCBs, for example<br />
with very large coils or pin-in-paste technology, frequencies<br />
and thus fan power as well must be increased<br />
in order to intensify heat transfer into the<br />
PCB. It’s advisable to check these PCBs for the presence<br />
of flow-sensitive SOD323s and, if necessary, to<br />
run a test with an assembled PCB if the frequencies<br />
need to be increased.<br />
If fluctuations occur for other parameters like connection<br />
surface tolerances or solder paste properties,<br />
different relationships must be reckoned with. For<br />
example, the tolerance-related reduction of the connection<br />
surface area to 0.25 x 0.3 mm, instead of the<br />
typical 0.3 x 0.45 mm, causes a yield force reduction<br />
to 40.9 µN. As a result, the component can no longer<br />
withstand the ascertained blowing force of 71.3 µN.<br />

The 5S lean manufacturing methodology in PCB production<br />
Improve benchtop cleaning,<br />
reduce waste with 5S<br />
Developed in Japan, 5S is a workplace organisation method used in physical<br />
manufacturing to eliminate waste. Elizabeth Norwood, Senior Chemist at cleaning<br />
solutions provider MicroCare, reveals how this lean, clean philosophy can be<br />
usefully applied in benchtop cleaning practices.<br />
extremely valuable process in PCB production, and<br />
especially benchtop cleaning. Adopting the 5S lean<br />
manufacturing method can help PCB manufacturers<br />
achieve better cleaning results at the benchtop, and<br />
thus increase efficiency and yield by reducing the<br />
number of faulty components and boards that land<br />
in the scrap pile.<br />
Optimising cleaning<br />
tools and workflow<br />
will lead to increased<br />
efficiency and reduced<br />
waste<br />
Although PCB shortages may be starting to stabilise,<br />
but the electronics industry continues to<br />
feel their impact. Exacerbating this issue for PCB<br />
manufacturers is the fact that the electronic components<br />
market continues to rapidly expand – with the<br />
sector predicted to grow by USD 122.44 billion (EUR<br />
116 billion) between 2022 and 2027, at a CAGR of<br />
7.02%. To avoid delays, PCB fabricators must find<br />
flexible and innovative strategies to ensure production<br />
continues. Options may include modifying designs or<br />
using alternative parts, but there is a more obvious<br />
solution: increase efficiency by decreasing waste.<br />
Electronics manufacturers must implement<br />
methods to ensure every electronic component is optimally<br />
utilised. An effective way to do this is to<br />
adopt tried and tested lean manufacturing processes<br />
such as the 5S methodology. This approach benefits<br />
all kinds of production environments and can be an<br />
Source: MicroCare<br />
What is 5S?<br />
The 5S philosophy can be summed up as: ‘a place<br />
for everything and everything in its place’. The name<br />
refers to five Japanese words beginning with ‘S’ that<br />
represent a 5-step process to organize the working<br />
environment. These terms can be translated into 5<br />
comparable English words:<br />
• Seiri/Sort: Separate tools/components that are<br />
necessary from those that are not.<br />
• Seiton/Set: Organise and categorise tools/components<br />
for ease of access and ease of use.<br />
• Seiso/Shine: Clean up the working environment.<br />
• Seiketsu/Standardise: Create standards and guidelines<br />
to uphold these practices.<br />
• Shitsuke/Sustain: Follow the first four ‘S’s on a<br />
long-term basis by always maintaining the correct<br />
procedures.<br />
Toyota first introduced something akin to the 5S<br />
methodology into its production in the 1950s – hoping<br />
to reduce manufacturing waste and inefficiency.<br />
It was discovered that by applying what later became<br />
known as the 5S concept, production ran more<br />
effectively because the workplace was clean and<br />
well-organised. This made it easier to see defects, all<br />
of which ultimately reduced waste and improved<br />
quality and output.<br />
The 5S strategy offers a large number of benefits<br />
to companies that adopt it. As well as reducing<br />
waste and optimising productivity, it also helps to<br />
enhance safety, improve quality and reduce costs. It<br />
is estimated that efficiency gains of 10% to 30% can<br />
be achieved using this method.<br />

5S and cleaning processes<br />
One of the main causes of PCB failure is contamination.<br />
If not cleaned sufficiently, PCBs are susceptible<br />
to many problems – from electrochemical migration<br />
and delamination to parasitic leakage, dendrite<br />
growth and shorting. Cleaning is crucial to ensuring<br />
the reliable, long-term performance of a PCB.<br />
Cleaning processes should be quick and consistent.<br />
Implementing the 5S methodology helps achieve this<br />
goal.<br />
Seiri / Sort<br />
To begin, it is essential to look at all the items on<br />
the benchtop and ask yourself the following questions:<br />
• Is this item necessary to clean the PCB and electronic<br />
components?<br />
• When was it last used?<br />
• Does it clean effectively?<br />
In this way, you can determine which items on the<br />
benchtop are required for the job. Certain tools and<br />
cleaning fluids may have worked well last year but as<br />
new designs and components are introduced, these<br />
may no longer perform as they once did. A no-clean<br />
solder paste may have been added to the assembly<br />
process and the available flux remover may not be<br />
strong enough to remove the stubborn no-clean flux<br />
white residue, for instance. Perhaps a fragile or<br />
moisture-sensitive component has been added to the<br />
design which can only be hand-soldered. Selectively<br />
soldered PCBs usually undergo ‘spot-cleaning’ at the<br />
benchtop using aerosol flux remover and a brush but<br />
if the cleaning fluids are too strong for these delicate<br />
components, they can cause damage and result in<br />
scrapped boards.<br />
A controlled cleaning fluid dispensing system is an<br />
essential tool on every PCB cleaning bench. When<br />
appropriately used, this system improves PCB cleaning<br />
results by targeting dirty areas on the board, getting<br />
under low-mounted components and permeat-<br />
Contaminated PCBs<br />
typically will not pass<br />

The second step is ‘set’ or ‘straighten’. This is at the<br />
heart of the phrase ‘a place for everything and everything<br />
in its place’. All items that have been deemed<br />
necessary should be organized logically and<br />
methodically. This can be achieved by giving each a<br />

cuts down on search time.<br />

holders on the work bench legs frees up workspace<br />
and keeps cleaning fluids easily accessible – meaning<br />
less time spent looking for the appropriate fluid.<br />
Seiso / Shine<br />
Shine refers to cleaning. Everything must be clean,<br />
tidy, and neatly stored in its place. How can the PCB<br />
or components be clean if the benchtop you are<br />
working from isn’t? If a benchtop is covered in dirt<br />
and dust, it will negatively affect the cleaning process<br />
and exacerbate other problems like electrostatic<br />
discharge (ESD).<br />
ESD is a major cause of PCB failure and is estimated<br />
to cause a third of PCB losses. It occurs when<br />
a board comes in contact with an object with the opposite<br />
electrical charge and creates an ESD spike,<br />
This damages boards and their sensitive electronic<br />
components.<br />
While it is impossible to prevent or eliminate all<br />
ESD, some practical ways to reduce it during SMT<br />
(surface mount technology) production include<br />
keeping the benchtop clean. Many work surfaces and<br />
tools used to assemble, clean and test PCBs hold<br />
static charges. It is important to dissipate the<br />
charges and remove the dirt by wiping down all tools<br />
and surfaces with pre-saturated, ESD-reducing<br />
cleaning wipes.<br />
ESD wipes are formulated to remove grime, grease<br />
and fingerprints without leaving lint, residue or<br />
static charges behind. They are a good general cleaner<br />
that will not dry out the ESD mats, cause fissures<br />
or leave mats brittle. Cleaning with ESD pre-saturated<br />
wipes helps ensure tools, surfaces and equipment<br />
are both clean and non-conductive.<br />
Seiketsu / Standardise<br />
This step ensures that all the progress made in the<br />
first three steps are not for nothing. By standardising<br />
these steps, 5S becomes a repeatable process that<br />
every technician follows. Creating a checklist and<br />
ensuring all workers follow the same procedures, and<br />
carry out cleaning processes correctly, will help ensure<br />
that consistent, high-quality PCB cleaning becomes<br />
standard practice. This in turn will help to reduce<br />
waste.<br />

PCB & ASSEMBLY «<br />
Shitsuke / Sustain<br />
Sustain is the final stage that helps technicians<br />
maintain all that has been implemented over the<br />
previous four stage. Companies must maintain the<br />
5S procedures and update and adapt them as<br />
necessary.<br />
It is essential to involve the entire workforce in the<br />
5S approach: the management team, those working<br />
at the PCB cleaning workbench, and staff in inspection<br />
and quality control. Regular training is a good<br />
way to keep everyone updated on the process and to<br />
ensure long-term success.<br />
The sixth ‘S’<br />
An additional sixth step that some companies<br />
adopt when using the 5S methodology is ‘Safety’. It<br />
concentrates on eliminating workplace risks and<br />
raising standards.<br />
It is important to examine cleaning fluids and<br />
equipment and carefully review the SDS (safety data<br />
sheets) to make sure they are appropriate for usage.<br />
Advanced PCB cleaning solutions are safer for exposed<br />
employees since they are designed to be nonflammable,<br />
have better toxicity profiles, and high<br />
threshold limit values (TLVs), making them safer for<br />
users.<br />
As mentioned above, a controlled cleaning fluid<br />
dispensing system is an effective tool. Cleaning fluid<br />
is distributed through a closed aerosol system, restricting<br />
worker exposure to any gases and lowering<br />
the possibility of spillage<br />
and fire hazards.<br />
As component shortages<br />
continue, PCB manufacturers<br />
are making every part<br />
count. Ineffective PCB<br />
cleaning not only affects the<br />
quality and reliability of any<br />
electronic device but can<br />
also leave the PCB unusable.<br />
When considering PCB<br />
cleaning, look for methods<br />
like ‘5S Plus Safety’ to help<br />
to optimise the process, and<br />
reduce waste.<br />

No-code / low-code tools simplify and speed up robot programming thanks to their template-based approach<br />
Implementing robots in a time and cost-efficient manner<br />
Why no-code & low-code tools<br />
are vital in robotics<br />
There are various stumbling blocks when it comes to implementing automation tools<br />
that users often underestimate. In this article, automation solutions provider Artiminds<br />
reveals how new no-code and low-code software tools can help manufacturers avoid<br />
these pitfalls and facilitate flexible, simplified robot programming.<br />
» Silke Glasstetter, Head of Marketing, ArtiMinds Robotics<br />
Using robots is almost always worthwhile for<br />
companies. They can reduce labour costs, relieve<br />
employees, and make production more flexible<br />
– particularly as batch sizes become smaller and production<br />
processes more individual. Another major<br />
advantage of robots or cobots is that they work<br />
without breaks or fatigue, thereby increasing product<br />
quality and reducing scrap.<br />
Almost all processes can be automated using modern<br />
robot systems. Robots are often used for simple,<br />
dirty, monotonous, physically demanding, and even<br />
dangerous tasks. With the right hardware and, more<br />
importantly, software, however, highly complex or<br />
demanding tasks can also be tackled using ‘Advanced<br />
Robotics’. Examples of such applications include the<br />
assembly of flexible and bendable components such<br />
as cables, wires, or hoses or force-controlled surface<br />
processing.<br />
In line with the no-code/low-code trend, various<br />
software solutions on the market now enable graphical<br />
(and therefore simplified) programming. The advantage<br />
of this is that no special programming skills<br />
are required. The portfolio of solutions in this area<br />
ranges from manufacturer specific to independent<br />
offerings that can be used to program robots from<br />
different manufacturers using just one single piece<br />
of software. In the latter case, experts recommend<br />
using tools that automatically generate native robot<br />
code for the particular robot controller instead of<br />
controlling the robot arm via a separate IPC. In the<br />
former case, users are able to remain flexible when it<br />
comes to adjustments or optimizations during operation<br />
because they can continue to program the<br />
robot using line code (even without using the software),<br />
and thus avoid a lock-in effect.<br />
Regardless of whether you are using external en-<br />

gineering tools or line code, there are obstacles on<br />
the path to robot-based automation that users often<br />
underestimate. Here are some tips on how to avoid<br />
three of the most important stumbling blocks.<br />
Programming effort<br />
The time required to program an application is not<br />
usually underestimated, but there are other pitfalls<br />
during this phase. These include process tolerances<br />
and variances that have not been taken into account;<br />
the increased complexity of incorporating<br />
sensors, or establishing communication between the<br />
robot and a PLC. Programming a system is often a<br />
tailor-made and complex process that is difficult to<br />
adapt. Programmers often have their own style,<br />
which can make the resulting code or program difficult<br />
for other programmers to understand and/or<br />
modify. In this case, the no-code/low-code solutions<br />
currently on the market can better support users.<br />
Thanks to pre-defined function blocks, programs can<br />
be constructed and structured in a clear and understandable<br />
manner. Using the right software, process<br />
tolerances and variances can also be automatically<br />
compensated, analyzed, and optimized. If the corresponding<br />
interfaces are already integrated, the effort<br />
required to connect sensors or set up a PLC communication<br />
is also significantly reduced.<br />
Effort during commissioning<br />
Programs can be structured and made traceable using pre-defined function blocks.<br />
Before commissioning, the process can be simulated as realistically as possible in a 3D<br />
simulation environment and tested<br />
A rule of thumb states that the cost of the robot<br />
itself is only about one third of the initial cost of the<br />
cell, and experience reveals that around 45 percent<br />
of typical costs are incurred during ramp-up. This is<br />
because users often underestimate the time required<br />
for commissioning. Although the system is programmed<br />
offline and simulated in advance, discrepancies<br />
between theory and practice often only become<br />
apparent during commissioning. This means<br />
that, despite preparation, the process can take significantly<br />
longer than<br />
planned, and necessary adjustments<br />
can quickly become<br />
expensive. Factors that were<br />
not apparent during digital<br />
preparation may need to be<br />
addressed on-site during commissioning.<br />
This makes this<br />
phase difficult to calculate.<br />
Using consistent tools, rampup<br />
can be implemented in a<br />
controlled manner, and with-<br />

does not become a cost driver. It is important to<br />

having to compromise on functionality. This makes it<br />
faster, more flexible and easier to make changes and<br />
adjustments. With automatically-generated code<br />
and the ability to transfer teach points back from the<br />
robot into the software, this kind of solution can integrate<br />
seamlessly into existing commissioning and<br />
maintenance processes. It also offers the greatest<br />
flexibility in terms of online and offline programming,<br />
allowing the user to choose the easiest option<br />
to complete the respective task.<br />
Changes during cell lifecycle<br />
Over the system runtime, various changes in general<br />
conditions may occur that necessitate adjustments<br />
in programming. These could be vibrations<br />
and shocks caused by forklifts or other machines;<br />
wear and tear of tools; replacement parts that react<br />
differently from previous components or changes in<br />
workpiece batches, available space, or operating personnel.<br />
Lighting or temperature fluctuations, or the<br />
contrast between a cold-started and warmed-up<br />
robot can also have an impact.<br />
Software that standardizes and simplifies programming<br />
allows the user to react quickly and flexibly<br />
to these and other changes in conditions and to<br />
make the necessary adjustments to the program. A<br />
worker can ensure they are best prepared by using a<br />
tool that is able to make changes or visualize consequences<br />
in terms of forces, cycle times, defects and<br />
quality even earlier.<br />

With high demand for microchips, the industry<br />
needs an efficient way to manage<br />
the volume and turnaround time during<br />
burn-in, a process to detect early failures<br />
in semiconductor devices. Manual burn-in<br />
methods — including hand placement,<br />
manual flipping, and manual stacking —<br />
are slow, error-prone, and can damage<br />
delicate wafers, ultimately leading to<br />
costly downtime and product defects.<br />

Achieving autonomous inspection<br />
How AI is revolutionising<br />
AOI and AXI systems<br />
Be it AI-supported inspection programme creation or AI<br />
classification of pseudo-defects at the verification station, the<br />
first steps towards achieving autonomous inspection have been<br />
taken. To take even more work off operators’ hands, AOI and AXI<br />
assistance systems are now being developed. Yet there’s still<br />
some way to go before optical inspection is fully automated.<br />
» Christina Schellbach, Public Relations Manager & Andreas Tuerk,<br />
Product Manager AXI, Goepel electronic<br />
Among other things, AI is<br />
used in the creation of<br />
inspection programmes<br />
and defect classification.<br />
The goal: to<br />
reduce effort and save<br />
costs. Personnel resources<br />
can be deployed elsewhere<br />
in the company<br />
AI evaluation of a welded<br />
joint in the X-ray image<br />
directly in the production line<br />
Historically, there have been several technological<br />
paradigm shifts in the field of AOI and AXI<br />
systems,” says Andreas Tuerk, product manager for<br />
X-ray systems at Goepel electronic. First, AOIs employed<br />
orthogonal cameras with illumination variants.<br />
Then oblique cameras and more sophisticated<br />
illumination of different wavelengths and directions<br />
were added. After that, 3D imaging technology was<br />
integrated to evaluate solder joints even more reliably.<br />
AXI systems have undergone a comparable<br />
trajectory. The vertical (2D) and oblique (2.5D) radiography<br />
of an assembly, mostly with analogue image<br />
intensifiers, gradually developed into 3D X-ray systems<br />
for solder joint inspection across several layers.<br />
The advent of 64-bit technology and powerful digital<br />
x-ray detectors then made AXI fast enough to use in<br />
the production line. “Until now, any fundamental<br />

52 <strong>EPP</strong> <strong>Europe</strong> » 11 | 2023
changes in inspection technologies have been hardware<br />
related,” Tuerk explains. “The next paradigm<br />
shift will be in the area of software. And artificial intelligence<br />
will be the driver.”<br />
Saving costs and personnel<br />
In addition to machinery acquisition and maintenance<br />
costs, personnel costs have the biggest impact<br />
on the price of inspection processes. In addition to<br />
personnel to classify abnormalities at the verification<br />
station, experts are required for the creation of inspection<br />
programmes. In this area, AI can reduce<br />
human effort and save money. A clear trend for customisation<br />
is evident among electronics manufacturers<br />
across the world – small batch sizes need to be<br />
produced and inspected quickly and, of course, costeffectively.<br />
In this case, an inspection programme<br />
that works from the first assembly can be created in<br />
just a few clicks using various assistance functions.<br />
Thanks to artificial intelligence, this will be achievable<br />
without the intervention of an employee in the<br />
future - contributing significantly to a reduction in<br />
inspection costs for very small batches.<br />
The future of programme creation<br />
Artificial intelligence has been used in Goepel inspection<br />
systems for several years. The time employees<br />
require to conduct various processes is already<br />
being reduced. Step by step, beginning with<br />
the semi-automation of processes, we are moving<br />
towards the final goal – fully automated,<br />
autonomous inspection.<br />
In the past, inspection programmes began with<br />
data import. Article numbers were manually assigned<br />
to existing library entries. Finally, the test parameters<br />
were manually adjusted. All of this was time-consuming.<br />
Nowadays, this process looks a little different<br />
- although automated programme creation still<br />
starts with data import. Component parameters<br />
Christina Schellbach,<br />

Manager at Goepel<br />
electronic<br />
(name, position, article number, and so on), layout<br />
and pad information are now readily available but<br />
detailed information about the housing and the<br />
solder joint (dimensions, height, pin shape) is still<br />
missing. To obtain this, the 3D AOI system creates an<br />
exact image of the respective housing and solder<br />
joints using the first produced assembly. This information<br />
is then used to determine the respective<br />
enclosure shape and to assign all required test functions.<br />
The test programme is created and a component<br />
library is automatically generated based on article<br />
numbers. In the final stage, the test programme<br />
is executed and the test parameters are automatically<br />
adapted to the real process variations. To avoid<br />
slippage, tolerance limits are placed tightly around<br />
the actual measured values and corrected according<br />
to real fluctuations, taking plausibility criteria into<br />
account. This is called knowledge-based intelligence.<br />
In the future, it will be possible to create a test programme<br />
without the real image of the first assembly.<br />
A completely digital image of the PCB with components<br />
and solder joints – a digital twin – will be used<br />
in the creation of a new test programme without the<br />
need for an actual physical assembly.<br />
“There are already AI inspection functions that do<br />
not require any setting parameters because they use<br />
a pre-trained AI model for classification,” explains<br />
Tuerk. Examples of this include the x-ray inspection<br />

AI evaluation of a QFN pin solder joint in a 3D X-ray image with AI advisor<br />
of prismatic battery cells for foreign objects or the<br />
AXI inspection of sheath thermocouples directly in<br />
the production line. As a human being, you often see<br />
certain defect features quickly – but the machine<br />
needs an expert who has mastered the parameterisation<br />
of an inspection function in order to be able<br />
to evaluate a feature correctly. This is where AI can<br />
help. The AI system is trained using example images.<br />
This results in an AI model that carries out the evaluation<br />
without any setting parameters. This is exemplified<br />
in the evaluation of welded joints on sheath<br />
thermocouples.<br />

Résumé<br />
Bien que nous n’ayons pas encore de système<br />

permettent déjà aujourd’hui de créer et d’optimiser des<br />

Further AI applications are in the works. In x-ray<br />
inspection, AI solutions for void detection, BGA<br />
head-in-pillow detection and short-circuit control<br />
are already being developed. AI approaches are<br />
emerging in predictive maintenance and for the<br />
analysis of results data from inspection systems<br />
across the whole SMT line. “There’s a long way to go<br />
before we achieve fully-automated inspection but<br />
we shouldn‘t forget how far we’ve come,” says Tuerk.<br />
AI at the verification station<br />
AI is not only saving human resources in the creation<br />
of inspection programmes. There is also the potential<br />
to save time and money at verification and repair<br />
stations. Goepel electronic relies upon the AI advisor<br />
software module for this purpose. Based on pretrained<br />
models, the AI advisor makes its own decision<br />
for each anomaly found by the inspection system. The<br />
AI‘s decision is based on the verification decisions<br />
made by humans in comparable cases in the past.<br />
Now there are different options for deploying AI decision-making.<br />
Anomalies that are classified with high<br />
confidence as pseudo errors can be evaluated directly<br />
by the AI – without human intervention. This saves<br />
time. The AI advisor can also warn us about whether<br />
a human error could lead to a so-called human slip. If<br />
an operator incorrectly classifies a real error as a<br />
pseudo error, the user is asked to reconsider his decision.<br />
Especially in the case of X-ray images – where<br />
error interpretation is often more demanding – the AI<br />
advisor can be a welcome aid. Its functionality is constantly<br />
being expanded with the aim of a fully autonomous<br />
classification of all abnormalities found.<br />
Trust is good – control is better!<br />
“Often there is still a sense of unease about the<br />
use of artificial intelligence in the field of inspection<br />
systems” notes Tuerk. “Why did the AI decide one<br />
way and not another? Will the AI find previously discovered<br />
defects even after it has been trained with<br />
new image samples? These are all legitimate questions.<br />
Luckily we already have some answers. The AI<br />
must be trustworthy – decisions must be comprehensible.<br />
With this in mind, Goepel electronic is<br />
working on ‘Comprehensible AI’ to increase trust and<br />
acceptance. We shouldn’t forget AI is only as good as<br />
the human who trained it, and this depends entirely<br />
on data selection, its completeness and consistently<br />
correct labelling and categorisation,” says Tuerk.<br />
There may still be some way to go before we<br />
achieve fully-autonomous inspection but, thanks to<br />
AI, the next paradigm shift is already well underway.<br />

blue (no contact/few contacts) to<br />
red (heavily touched areas)<br />
intelligence which automatically optimize the<br />
test flow in run-time, while maintaining test<br />
coverage targets<br />
The prober can accommodate fully loaded doublesided<br />
boards with components that need to be programmed;<br />
LEDs that require electrical and optical<br />
testing; flex circuits; and board sizes and components<br />
ranging from very small to very large. Using<br />
the FlyStrain option, the Pilot VX can now also generate<br />
pressure/force topology maps of the device<br />
under test.<br />
Once a necessity for traditional fixture-based solutions,<br />
these new tools have been migrated to the flying<br />
prober where testing of ceramics, wafers and<br />
avionics and satellite boards requires delicate probing<br />
and traceability. The new option generates a graphical<br />
interface for fast analysis and log file for statistical<br />
analysis. This kind of analysis is already conducted on<br />
sample boards for Bed-of-Nails systems.<br />
Using the new option, the runtime tool measures<br />
the force as soon the electrical contact is stable. The<br />
contact is continuously monitored, and when the<br />
probe reaches the contact height, the system reports<br />
the contact pressure for each single test point. The<br />
final result is visualised via a coloured map using a<br />
scale from blue (low stress point) to red (high stress<br />
point).<br />
In summary, the Pilot VX with FlyStrain programmer<br />
tool is a flexible, configurable test system<br />
with a set of technologically-advanced tools. It provides<br />
the test solutions required by the huge diversity<br />
of electronics which characterizes today’s high-volume<br />
production environment.<br />
