Interview with Daniel Schultze, Managing Director of Tresky

“We do not offer a machine,

but a ready-made application”

Tresky manufactures die bonding systems for high mix–low volume

production programmes. Managing Director Daniel Schultze explains

why the company places particular focus on the development and

production of fully-automatic machines.

EPP Europe: Tresky is one of about eight companies

in the world that offer fully automatic die

bonding machines for the electronics and semiconductor

industries. You specialise in high-precision

bonding of high mix–low volume production

programmes with emphasis on single laser, laser

bars and sensor technology. How did this corporate

focus come about?

Daniel Schultze: The initial impulse to begin this

work came through close cooperation with customers

such as Jenoptik, and regular contact with universities

and research institutes. It is an alliance

which benefits both parties. We had already built up

a knowledge of the area by developing appropriate

solutions for various tasks. This expertise enables us

to develop a custom-fit solution for almost any

problem a customer has. We start in CAD and can

react very flexibly to their requirements. All the

while, we maintain close ties with universities because

of their research capacities. If research and industrial

development work together from the outset,

something good usually comes out of it.

EPP Europe: Can you give an example of this

kind of collaboration?

Daniel Schultze: We are currently in the process

of evaluating a research project in collaboration with

Kiel University of Applied Sciences and other

partners to develop new modules for sintering highand

low-power components. These components are

used in the e-mobility sector, in e-cars, e-bikes and

e-motorbikes; but they can also be found in wind

turbines and high-voltage converter modules, in

smart refrigerators and military applications. Developments

in the field of autonomous vehicles, along

with the phasing out of fossil fuels, are driving the

development of this technology, as these sectors

require specific types of electronics.

high-wage paying country, cannot compete with

Asian manufacturers. The German market is therefore

not attractive to companies that want to pro-

duce machines in high quantities with as few adjustments

as possible. We do not see ourselves merely as

machine builders, but as a solution-oriented partner

for our customers. After all, we can offer an extremely

broad field of knowledge and high level of

flexibility. We put the expertise of our engineers at

the disposal of our customers whenever they require

a customised system. We are able to take specific

requirements into account and, because we have a

thorough understanding of our customers’ applications

and target markets, they really benefit from

our mechanical engineering and application experience.

We also attach great importance to service and

maintain close contact with our customers. This enables

us to upgrade the machines we develop, regardless

of their configuration, with a wide range of

options - even many years later. Since our machines

are flexible and modular in design, product or technology

changes can be made at any time using appropriate

applications and extensions. Our service

technicians are also available to provide assitance if

required. Satisfied customers who appreciate us and

recommend us to others are far more important to us

than a quick sale.

Daniel Schultze, Managing Director of Tresky

EPP Europe: You believe in the maxim: ‘it is not

the big that eat the small, but the fast that eat the

slow’. What is Tresky‘s vision for the future?

Daniel Schultze: It is clear that our die-bonders are

in demand. This was evident even during the recent

pandemic. Electronics continued to be produced during

this time despite fragile and expensive supply

chains. Our high level of flexibility enables us to continue

developing interesting technologies, and we

are expanding. We would like to move to larger

premises before the end of the year and hire more

people. It is, however, difficult to find qualified employees.

For this reason, we are in contact with various

universities and Fraunhofer Institutes, and offer

support to students with their undergraduate and

master‘s theses. Our goal is to connect potential employees

with Tresky at an early stage in their careers.

8 reasons to embrace supply chain digitalisation

Should you make your supply

chain digital?

While it is true that that industries across all sectors are embracing digitalisation, many

supply chains continue to be held back by their outdated approach. Here, Jeff Brind, Chief

Information Officer at independent electronic components distributor Rebound Electronics,

looks at some of the key reasons you should make your supply chain digital.

Source: Rebound Electronics

Rebound says its global team can offer real-time global market intelligence from a single

point of contact

In such uncertain times, any change that increases

the predictability, visibility and reliability of the

flow of goods and materials in the electronics manufacturing

supply chain can only be a positive one. If,

however, you are still unsure about whether acrossthe-board

digitalisation is really necessary, here is

some food for thought...

1. Digital supply chains are more

resilient

Digitalisation can increase visibility throughout

your entire supply chain, which makes it easier to

identify risk at every point of the supply chain and

respond before delays occur. Supply chains that invest

in automation and new technology are also

more resilient in times of disruption because they are

less reliant on physical labour and certain processes

can continue outside of working hours.

2.Digital means increased

visibility

Visibility is increased in a digital supply chain, and

this brings more than just increased resilience. Endto-end

visibility and transparency are increased

without the need for user input, instead using lowcode

automation platforms to provide access to realtime

information to all businesses involved. This information

can include manufacturing progress reports,

location of parts and delivery status, meaning

supply chains can work to more accurate timeframes.

The electronic components distributor also offers climate-controlled certified warehousing in Europe and Asia


8 EPP Europe » 11 | 2022

NEWS & HIGHLIGHTS «

3. Digital supply chains have a

competitive advantage

A digitalised supply chain can give manufacturers

an advantage over competitors because it enables

them to manufacture products more efficiently and

deliver a better service for the end user. Increased visibility,

traceability and communication throughout

the supply chain results in fewer supply issues, and

automated warehousing processes help to create

products much quicker and with a reduced risk of

error.

4. You can generate data-driven

plans

Digitalising your supply chain gives you access to

more data and more opportunities to put that data

to good use. For example, analytics and data visualisation

can benefit activities such as demand forecasting.

Combining intelligent algorithms and historical

data allows you to predict customer trends, giving

you more time to source the components to meet

that future demand. This is particularly useful for

orders that use hard-to-source components and

those that are currently experiencing a shortage.

5. Warehouses are more efficient

A digitalised warehouse is more operationally efficient

through the use of AI systems, automation and

improved access to data. AI systems can work out

the shortest, most efficient walking routes through

the warehouse and they can also be used to better

position the inventory for ease of access to the most

popular parts. Robotics can be used for loading and

unloading pallets, moving cargo and more, resulting

in a far more streamlined warehouse.

6. It is easier to manage

inventory

Digital stock management is more

efficient and less susceptible to human

error. Stock levels can be monitored remotely

and in real time, and parts or

compontents can be automatically ordered

once stock drops below a set

level.

With traditional ordering methods, it

is easy to underorder or miss a delivery

date, which could result in the loss of a

sale if a product is out of stock. On the

other hand, overordering can result in

excess stock that could become obsolete

and need offloading, and at the least

will result in additional storage costs.

7. Transit becomes more efficient

Cloud-based GPS and BLE asset tracking increases

the availability of data for supply chains, providing

real-time insights into the status and location of assets,

even when they are in transit. The efficiency of

the fleet can also be drastically improved by analysing

route efficiency and traffic conditions.

8. Labour can be used more

effectively

By investing in automation technology, employees

can be put to work more efficiently. Automation programs

can take over many menial and administrative

tasks (and even complete them outside of business

hours), while employees can focus on the more complex

tasks that only they can do, meaning that more

important work can be completed during a typical

shift.

Employees also won’t have to work longer hours to

complete these routine tasks, where increased fatigue

could increase the occurrence of costly errors.

To sum up...

Digitalisation is essential for any manufacturing

business that wants to remain competitive in the

modern climate. As these benefits demonstrate, the

question is not ‘should you make your supply chain

digital?’, but ‘how soon can you start?’.

Boost for U.S. semiconductor industry

Biden signs U.S. Chips and Science Act into law

President Biden has signed an Executive Order to facilitate

the implementation of the bipartisan Chips

and Science Act. The long-awaited piece of legislation

which includes measures to provide USD 52

billion dollars to the country‘s semiconductor industry

to mitigate supply shortages and boost domestic

manufacturing of chips. Sometimes known just as

the Chips Act, the new policy is aimed at

strengthening U.S. science and technology innovation,

but also addresses concerns that the country

is too reliant on Asian manufacturers of chips. After

months of revisions, the bill passed the Senate on 27

July and was approved by the House of Representatives

on 28 July in a vote of 243-187. President

Biden signed it into law on 25 August 2022.

In addition to billons of dollars of subsidies, the

legislative measures include the provision of billions

of dollars worth of tax incentives to chipmakers to

encourage them to build semiconductor fabrication

plants or ‘fabs’ in the United States rather than elsewhere.

In January, Intel revealed plans to build $20

billion chip plant near Columbus, Ohio but postponed

its ceremonial address at the site in July while it

waited for Congress to pass the Chips Act.

The U.S. currently accounts for 12% of global semiconductor

manufacturing; in 1990, its share was

37%. Speaking on 26 July in a meeting with CEOs

and Labor Leaders on the importance of passing the

bill, President Biden said, “America invented the

semiconductor. It’s time to bring it home.”

New website for growing product segment

ODU launches online offering for mass interconnect interfaces

A leading suppliers of connector systems ODU has

launched a new website for its mass interconnect interfaces

product portfolio. These are now presented on

their own website www.odu-interconnect.com.

Just as in the development of its ODU-MAC Black-Line

mass interconnect interfaces, the company says it

wanted to make things as easy as possible for the user

with the new website. Thanks to its user friendly design,

the technology provider says, anyone who requires information

can get to it quickly and efficiently.

Contact technology

The company’s mass interconnect systems are mainly

used for testing printed circuit boards and electronically

assembled components. “What is decisive in this regard?

Reliable measurements and great flexibility,” the

company said in a statement. “Unsurprisingly, ODU‘s

contact technology is convincing … due to its high reliability.

Equally important is the individual configuration

of interfaces, for which the modular connectors

are ideally suited.”

“It was the next logical step to offer our own mass interconnect

interface,” said Tobias Eder, product manager

at ODU.

Continuous product enhancement

To meet the needs of as many applications as possible,

ODU says its portfolio is constantly being expanded. The

latest extension is a so-called electronics housing,

which can be used as an alternative to the adapter. It

allows connectors to be attached to the rear panel for

individual test requirements. At the same time, the

housing protects electronic components and cables.

Visitors will encounter smart energy everywhere at Electronica 2022, as electronics also has a key role to play in the energy transition

Electronica 2022, 15-18 November, Messe München

Sustainability to take centre

stage at Munich expo

In the four years since Electronica last took place in person, the industry (not to

mention the world) has undergone some seismic changes. Boasting a wide and

varied programme of supplementary conferences and forums, this year’s fair

will highlight today’s most pressing topics: from electromobility through smart

energy to power electronics and sensors.

Expectations are high for this year’s Electronica

event. The last time the trade fair was held in

real life, it attracted a record 80,000 visitors from

over 80 countries. Skipping over the expo’s purely virtual

outing at the height of the pandemic in November

2020 (which still managed to attract over 8200

participants), this year‘s edition looks set to be just as

popular. “Exhibitors, top decision makers and thought

leaders want to discuss innovations and trends in

person again at last and they’re already looking

ahead to the Fall with confidence,” said Dr. Reinhard

Pfeiffer, Deputy CEO of Messe München. “For them,

electronica is the world’s most important industry

get-together and the only one this year that seamlessly

covers the complete spectrum of electronics.”

Companies from over 40 countries, ranging from

start-ups to global corporations, will come together

across 13 halls to present products and solutions, and

exchange ideas about the future of the industry.

“Driving sustainable progress”

The motto for this year’s event is cleverly worded.

In addition to a strong emphasis on electronics as a

driver of sustainable technologies, the development

of sustainable automotive (or ‘driving’) technologies

themselves will also be in focus. As well as electromobility,

key topics at the expo will include smart

energy, industrial electronics and sensors – many of

which will be discussed in depth at the supplementary

conferences and forums.

The issues and challenges in the field of microelectronics

will be addressed separately at the co-located

event Semicon Europa, recognized as one of

the largest international trade fairs for semiconductor

manufacturing in Europe.

Smart energy

Recent events mean that the question of how we

attain energy sustainably is perhaps more pressing

than ever before. The 2022 show will highlight the

vital role of electronics technologies in the transformation

of energy infrastructures.

Smart energy refers to intelligent technologies and

solutions aimed at achieving efficient production,

distribution, use and storing of energy, across the entire

value chain. According to a study by the IMARC

Group, the global market for smart energy is expected

to increase at a compound annual growth

rate (CAGR) of 9.82 percent from USD 138.8 billion

in 2021 to USD 247.8 billion by 2027. Analysts ident-

ified the growing demand for intelligent electricity

grids—“smart grids”—as a main driver of this growth.

Power electronics are also of high importance

when it comes to energy saving. According to a study

by the European Center for Power Electronics (ECPE),

more than a quarter of electrical energy could be

saved through the use of modern power electronics.

Visitors will encounter smart energy everywhere at

Electronica 2022. The Power Electronics and Embedded

Systems Forums, which runs across 4 days

Koh Young examines the future of dispensing inspection (DPI)

Overcoming the

challenges of CCI

16 EPP Europe » 11 | 2022

AT A GLANCE

In this article, Koh Young

details the importance of

accurate CCI and

measurement, and explains

how its new 3D in-line DPI

equipment can conduct

2D and 3D inspection of

transparent materials.

Conformal coatings protect electronics

from moisture, debris, and corrosion.

They also add mechanical stability to

help reduce failures and improve an

electronic device’s reliability when it is

exposed to harsh environments. But

what happens if a coating is defective

or simply too thin? Koh Young discusses

the challenges of conformal coating

inspection (CCI) and how its latest

Neptune series can help.

A

conformal coating is a transparent protective

film with a thickness of around 50um applied

to a PCB to protect the board and its components

from corrosion (caused by vibration, temperature

changes, and so on) and from the environment. It is

used on parts that need to offer increased product

reliability via dustproofing and waterproofing. As

conformal coatings significantly reduce the chance

of circuit failure due to moisture, they are now being

increasingly applied to products which necessitate a

high level of reliability. There are various coating

methods used today including dipping, brushing, and

spraying. Selective spraying methods that only coat a

specific area are also being more widely used.

In addition to conformal coatings, various other

dispensing technologies such as underfill and overcoating

are emerging in the market. Underfill redistributes

the thermomechanical stress created by

the coefficient of thermal expansion mismatch between

the silicon chip and organic substrate and is

often applied to BGAs and CSPs in semiconductors

or during SMT processes. In some medical applications,

a droplet-shaped coating needs to be

placed on the pad, in a process known as overcoating,

and the height of this droplet needs to be

measured. Indeed, as this example makes clear,

some dispensing applications now also require specific

inspection processes.

3D inspection

Until recently, 2D inspection was all that was

required for conformal coating inspection; now however,

there is rising demand for 3D inspection. This

has come about because it is necessary to ensure the

coating attains a particular thickness. If the conformal

coating is applied too thinly, the parts that

require protection may not be sufficiently shielded.

If, on the other hand, the coating is applied too

thickly, the unnecessary stress this adds to the board

can cause side effects such as bubbles and cracks.

“Proper coating thickness is very

important to ensure the quality of a board

yet 3D thickness inspection is not easy

because the coating itself is transparent.”

IPC recommends a thickness of between 30um and

130um depending on the type of conformal coating.

Proper coating thickness is very important to ensure

the quality of a board, yet 3D thickness inspection is

not easy because the coating itself is transparent.

Biggest inspection challenges

So, what are the biggest challenges when it

comes to coating inspection? Conformal coatings

are done using different materials meaning that, in

some cases, the coating thickness and UV color

may be different – even for the same type of board.

As conventional 2D CCI (conformal coating inspection)

systems inspect according to the UV color,

and are susceptible to the board environment, this

can lead to a high rate of 2D false calls. In order to

solve these problems, it is also necessary to continuously

draw and set the region of interest (ROI).

Finally, as explained above, because the conformal

coating is itself transparent, 3D thickness measurement

using existing inspection technology becomes

a challenge. In the case of IC components, for instance,

we find that, because the coating flows

down, it remains thin on top of the leads but

relatively thick in between them because it has gathered

here.

In the case of underfill, there is a need to check the

fillet height using 3D. Accurate measurement is difficult

due to the steep slope of the fillet. Although, it

looks black, underfill may, in some cases, have some

transparency. Before curing especially, it is even

laser beam. The signal is split

into a reference signal and a

splitter). The overlay of both

more transparent. With a level of transparency like

this, there is no guarantee that the 3D shape is of the

correct height or not, as the light is slightly transmitted

when it is reflected. As such, it is difficult to

obtain reliable 3D data with existing CCI technology.

Currently, in order to ensure the reliability of 3D

measurements, some boards must be destroyed.

The Neptune series

To help overcome these challenges, Koh Young has

launched the Neptune series for conformal coating

inspection. The tabletop Neptune T and the inline

Neptune C+ machine. The tabletop machine is optimized

for thickness measurement, and the Neptune

C+ is the industry‘s first 3D in-line DPI, (Dispensing

Process Inspection) system, which is able to offer

both the 2D and 3D inspection of various transparent

materials.

In addition to 2D conformal coating inspection,

Neptune C+ also provides solutions for various areas

that undergo 3D inspection. As explained above, in

existing 2D CCI, defects are detected using only the

UV brightness color, leading to frequent false calls.

Bubble detection is, for instance, an area with a very

high false call rate.

In order to minimize this false call rate, Koh Young

employs an image-based machine learning-algorithm

for bubble detection. First, bubble images from

the field are collected, and classified by bubble shape

based on the collection of images, in order to continuously

enhance the bubble detection engine. The

“It is difficult to obtain reliable 3D data

with existing CCI technology.”

Neptune C+ thus enables customized bubble detection

according to bubble classification. For example,

some customers may wish to class a bubble that occurs

far away from the lead as not defective, while

others prefer to classify any bubble – no matter

where it is detected – as a defect.

User-friendly software

Programming that was difficult with existing CCI

systems has also been made easier by our userfriendly

software. The user interface is very intuitive

and easy to use. Everything from recipe creation to

result review is possible in one piece of software.

Drawing the ROI is also very simple using a rectangle,

circle, polygon, and so on. After selecting a

type of inspection, the user need only to draw an

ROI, and the inspection process is ready to go.

Most importantly, Koh Young’s systems provide the

most accurate and reliable 3D inspection regardless

of the surface condition of transparent materials.

Unlike other CCIs, the Neptune can inspect within 3

minutes without any damage to the board. Existing

CCI systems normally measure the height by adjusting

the position of this reference mirror, but our

technology does this by adjusting the frequency.

Also, instead of inspecting only one point, our CCI

systems deliver tomographic information by area inspection.

As such, the image shown above is acquired,

and as you can see, multiple layers of fluid

structure can be clearly seen.

DPI beyond CCI

Our Neptune C+ can perform 2D and 3D inspection

of conformal coatings, as well as 3D inspection of

underfills and overcoatings. Currently, it offers a

measurement range of 10 microns to 3.5 mm for

these transparent materials, in the absence of refraction.

Moreover, just to briefly explain the hardware,

it has a 12M pixel camera and 15um. There is not

much difference in size from the existing SPI and AOI

systems, but in the case of the Neptune C+ we also

have a flipper-type ready system so there may be

some differences in PCB thickness and machine

weight.

Removing insoluble particulate from semiconductors

Vapor degreasing explained

Vapor degreasing is an efficient and sustainable way of removing contaminants,

like insoluble particulate, from semiconductor wafers and components.

In so doing, it helps to ensure their later reliability and operability, as Senior

Chemist at MicroCare, Elizabeth Norwood, explains.

Semiconductor manufacturing typically

takes place in cleanrooms to protect the

complex chips from contamination. But

almost all semiconductor wafers need

some cleaning during manufacture to reticulate

accumulates on the wafer surface,

it can interfere with and degrade

deposited films that come later. It can

also cause shadowing during lithography,

reduce contact exposure resolution or

create an uneven surface that could result

in cracking during exposure.

Particulate is also a common contaminant

found on FOUPs (Front Opening Unified

Pods) used for wafer transferring. So,

the FOUPs should also be cleaned to prevent

FOUP-to-wafer contamination.

Particulate is not soluble in traditional

cleaning fluid, so it must be removed by

either chemical or mechanical means.

There are various ways to clean semiconductors

and FOUPs. One is via vapor degreasing

with specialty particulate displacement

fluids.

Vapor degreasing combines cleaning, rinsing and drying in one step to optimize throughput time

Demand for sophisticated, complex

electronics is rising. But the intricate

nature of these assemblies, which

include delicate semiconductor wafers,

can cause a reliability risk if post-etching

cleaning is not performed well. Contaminants

must be removed without damage

or alteration to the wafers. Failure to remove

these impurities could cause etching,

corrosion or pitting, resulting in poor

semiconductor operability and reliability,

Cleaning semiconductors

move contamination resulting from the

manufacturing process. Contaminants

come from many sources including chip

transport, handling, storage and manufacturing.

Soils vary and can include dust,

fingerprints, oils and water.

One of the most common semiconductor

contaminants is particulate. This comprises

dust particles, skin flakes, fibers

and other process contaminants. Particulate

contamination comes from the air,

from the abrasion of moving parts, from

clothing, or from dirty, unfiltered etching

fluids. These particles either electrostatically

bond to the substrate or they get

trapped in the wafer substrate geometry.

Particulate impacts wafer performance

in different ways. For example, as par-

What is vapor degreasing?

Vapor degreasing is a closed-loop system

with two components: a vapor degreaser

and particle displacement fluid.

Most vapor degreasing systems are toploading

batch-style cleaning machines

with two compartments: the boil sump

and the rinse sump. In the boil sump, a

batch of parts including FOUPs, MOSFETS

Bild: Microcare

Particulate contamination comes from the air,

from the abrasion of moving parts, from clothing,

or from dirty, unfiltered etching fluids

(Metal Oxide Semiconductor Field-Effect

Transistors) or other semiconductor components

are immersed in the heated fluid

for cleaning. Often, agitation helps enhance

the cleaning fluid’s effectiveness.

This is done by leveraging the boiling action

of the cleaning fluid, adding vibrating

ultrasonic energy or using a spray

wand to loosen the particulate off the

substrate. Once cleaned, the parts mechanically

transfer to the rinse sump. The

parts rinse in pure, uncontaminated fluid

or inside the fluid vapors themselves. The

components come out cool so they are

immediately ready for use or for the next

stage of processing. Unlike the commoner

aqueous cleaning, vapor degreasing combines

cleaning, rinsing and drying in one

step to maximize takt time. It takes as

little as 6–20 minutes per batch.

Moreover, vapor degreasers typically

have a smaller footprint than aqueous

cleaners. The systems take up less valuable

production space and, because vapor

degreasing cleaning is a simple, predictable

and repeatable process, it is easy to

qualify and validate for cleanroom use.

Good particle displacement

The displacement cleaning fluids used

inside vapor degreasers have chemical

and physical properties that are advantageous

to particle displacement and help

accelerate the cleaning process. Small

particles can be difficult to remove from

wafers since strong electrostatic forces

exist between the particles and the wafer

substrate. A particle adheres to the substrate

through adhesion forces, whether

it is an electrostatic charge or Van der

Waals force. This adhesion creates a friction

force parallel with the surface: static

friction if the particle is not moving, dynamic

friction if it is. To remove the contaminant,

the cleaning fluid must reduce

the thickness of the laminar boundary

layer, break the bond and allow the particles

to release from the substrate.

Some displacement fluids are a mixture

of hydrofluoro-olefin (HFO) and ethanol

that removes fine particulate down to the

micron or even sub-micron range. The alcohol

component forms hydrogen bonds

at the fluid-substrate interface, reducing

the intermolecular forces between the

particle and the substrate. This allows the

particulate to lift more easily from the

substrate.

Plus, the fluorocarbon-based fluids are

synthetically derived, allowing for a

higher purity level than traditional hydrocarbon-based

cleaning fluids. These

ultra-pure fluids dry quickly and completely

without leaving spots or residue

behind.

High density & low viscosity

Particulate displacement fluids are

dense: typically, 20–40% heavier than

water and 50% heavier than alcohol.

They also have a lower viscosity than IPA

(Isopropyl Alcohol), water or water with

surfactant additives. The combination of

the higher density and the lower viscosity

of the hydrofluoro-olefin fluids results in

greater drag forces acting on the particles.

This makes it easier to dislodge the

particulate from the substrate. The particles

push away from the substrate and

wash away, dispersing into the cleaning

fluid.

Low boiling point

Particle displacement fluids are lowboiling

with typical boiling points between

40˚C/105˚F and 65°C/165°F. This

minimizes the risk of damage to wafers

and other delicate components. Vaporization

displacement fluids (below 100°C)

are aggressive enough to remove the particles,

yet won’t damage the substrate,

including composite materials. They are

compatible with most hard plastics, ceramic,

glass and metal.

Low boiling fluids also allow the vapor

degreaser to run more efficiently. And

since vapor degreasing cleans and dries in

one step, there is no need for blowers, air

knives or any other drying method that

uses power. This translates into less fossil

fuel consumption, lower carbon emission

and reduced greenhouse gas output. All

with the added benefit of energy cost

savings.

Environmentally friendly

Environmentally-friendly HFO-based

displacement fluids replace higher GWP

(Global Warming Potential) hydrofluorocarbon

(HFC) and hydrofluoroethers

(HFE)-based fluids. They also are better

for the environment than high ODP

(Ozone Depleting Potential) solvents like

CFC-113, HCFC-141b, HFC-225 and 1,1,1

trichloroethane. They meet strict regional

air quality regulations and many are not

considered HAPs (Hazardous Air Pollutants).

Many fluids are accepted by key

environmental and governmental regulatory

agencies in the United States and

most countries around the globe. They

meet global environmental directives including

the European F-Gas and REACH

(Registration, Evaluation, Authorisation

and Restriction of Chemicals) legislation.

Environmentally sustainable

Vapor degreasing with particle displacement

fluids uses no water, conserving

this precious non-renewable resource.

In addition, the process doesn’t produce

wastewater that requires specialty filtration

or treatments before disposal.

Another environmental benefit of particle

displacement through vapor degreasing

is its suitability for recycling. The

displacement fluid is used for hundreds of

cycles before it requires refreshing or replacing.

Additionally, the vapor degreaser

concentrates the contaminants as it

works. This reduces waste generation and

lowers hazardous waste disposal costs.

Wrapping up

Particle contamination is detrimental

to intricate semiconductors and silicon

wafers. Removing contamination is essential

to ensuring their performance.

Vapor degreasing using particle displacement

fluid not only ensures semiconductor

cleanliness, it also addresses environmental

and regulatory concerns.

Companies looking for help with displacement

cleaning should partner with

an expert that has displacement fluid and

vapor degreasing expertise. They can conduct

on-site audits or perform in-lab

tests with sample wafers to ensure cleaning

success. Based on the wafer substrate

and the particulate, these specialists can

recommend, or engineer, the fluids and

processes that achieve the best results.

size of the boards it is able to process. The new system

is suitable for PCBs measuring up to 600mm x

510mm (approx. 23.6“ x 20“) - a 90 percent increase

compared to the DEK TQ. At 560mm x 510mm (approx.

22“ x 20“), the DEK TQ L’s printable area has

also grown by more than 78 percent. This generous

production format offers electronics manufacturers

new degrees of freedom. Not only can they print

larger PCBs but, with the speedy three-stage conveyor,

they can also process three substrates with a

length of up to 345 millimetres in one pass.

Off-belt speed with linear drives

ASMPT has also employed linear motors throughout

the DEK TQ L. This off-belt concept improves not

only the machine’s precision and repeat accuracy, it

also helps it deliver high processing speeds with a

core cycle time of 6.5 seconds or less with the threestage

conveyor. The innovative clamping system, a

more advanced printhead and the NuMotion controller

with fiberoptic cabling (developed by ASMPT)

further contribute to improvements in production

speed.

The high-speed understencil cleaning system also

operates with its own linear drives, which makes it

twice as fast as conventional systems. Additionally,

depending on the board size, the cleaning system

can be equipped with three different sizes of fabric

rolls that can be changed quickly and easily.

Zero-line-stop philosophy

The new platform‘s printers are designed to run for

more than eight hours without user intervention. For

normal cleaning cycles, a 22-meter fabric roll is long

enough for a whole shift, and the seven-litre cleaning

fluid tank requires a refill only after eight hours

or longer. The cleaning agent is applied (from above

via a dispenser) onto the board area being processed,

significantly reducing consumption. The pivot design

ensures coplanary contact with the stencil underside

for maximum cleaning quality.

To minimize manual assists, an optional paste

management system with automatic paste dispenser

and integrated paste height control with individually-configurable

warning and stop thresholds is

available. Also available to facilitate non-stop printing

is the optional Dual Access Cover, whose laterally

movable portion provides full access to the paste

cartridge so that it can be replaced while the main

cover stays closed and the printer keeps operating.

The three-stage transport system means that while a board is being printed, the one

previously processed is moved out and the following one is loaded

Needs-oriented automation

The DEK TQ L printer has been designed to fit in

with ASMPT’s Open Automation approach. This costoptimized

alternative to the fully-automated shop

floor has proved successful in electronics production.

By allowing users to automate existing lines and

processes in stages according to their needs, the

company offers a variety of solutions for step-bystep

automation for the new platform (based on ROI

considerations). As Jens Katschke, Senior Process

Solutions Manager at ASMPT, explains, “the various

automation options for the latest generation of DEK

TQ printers enable SMT manufacturers to design an

Integrated Smart Factory in accordance with their

own ideas without having to depend on a specific

equipment manufacturer.”

Customers who opt for the additional Smart Pin

Placement feature can also benefit from fewer manual

assists. The system operates with two pin sizes

(4mm and 12mm in diameter). In the DEK TQ L, the

magazine holds up to 60 pins and the system automatically

verifies the position and the height of each

pin after setting it. This prevents any single pin

which is perhaps minimally elevated by dirt on the

table from damaging the entire assembly.

Automation options for the Integrated Smart Factory

go even further. Together with the WORKS Process

Expert software, the Process Lens SPI system

partners with the DEK TQ L to form a system that is

as productive as it is functional. It provides the

printer with continuous feedback about the print

quality and can even modify settings on the system,

allowing the printing process control and optimization

functions to run autonomously. It can even

take process data from third-party systems into ac-

Thanks to standardized, open interfaces, it is just as

easy to integrate the new high-speed printer into an

The ED&A site in

Kalmthout, Belgium

Case study: Ersa soldering systems in practice

It all began with a coffee machine…

Manufacturer of soldering systems Kurtz Ersa chronicles the history of its

customer ED&A, a Belgian developer and manufacturer of custom-made

electronic controllers, and explains how the company came to rely on Ersa

systems once it started its own manufacturing operations in 2012.

For over 40 years, ED&A has been developing and

producing customized electronic controllers for

consumer and industrial applications. The company,

based in Kalmthout, Belgium, is more than just a supplier,

describing itself as the “in-house electronics

department” for its customers. As part of a recent expansion

of its production capacity, the developer has

expanded its machinery portfolio with the addition of

an Ersa Versaflow 4/55 selective soldering system.

Source: ED&A

ED&A has been awarded a Factory of the Future

designation by Agoria/Sirris for the third time

Background

ED&A was founded in 1981 by

Agnes Francken and her husband

Flor D´Handschotter, who

was at that point working as a

teacher of electronics. The idea

to start a company was sparked

after a student’s father asked

Flor to develop a controller for a

coffee machine. Not content

with simply saying, “yes, let’s do

it”, he seized the opportunity

and founded his own business. It

took four years before the enterprise

hired its first two employees

– and both are still

within the company. Fast forward 37 years and ED&A

employs 110 people (50 in production) and reported

a turnover of over 25 million Euros last year. 20% of

business takes place in Belgium, the rest is for export.

In 2009, Gert D´Handschotter took over management

of the business from his parents.

Centrally located in Kalmthout with a production

area totalling 5,000m 2 , the company’s current focus

is on the development and production of custommade

electronics for innovative machine and appliance

manufacturers, such as makers of washing

machines, ventilation systems, heat pumps, coffee,

and baked goods machines.

In-house production

On 8 October 2012, ED&A took the groundbreaking

step of opening its own production facility with the

help of various systems, including a number of Ersa

soldering machines. Having previously outsourced all

its manufacturing, mainly to Belgium and Romania,

the decision to manufacture its own designs inhouse

was made after intensive evaluation and research.

The quality of the outsourced electronic assemblies

did not always meet requirements and an

increasing number of bottlenecks was affecting

production capacity.

Part of the production opened in 2012: an Ersa stencil printer

View of the ED&A production – at the front: the Ersa Hotflow 3/14e reflow soldering system

One person was central to the transformation: Eric

Vets. Vets joined ED&A in November 2011, and

brought with him many years’ experience of electronics

production working for a large mobile phone

manufacturer where he had become very familiar

with Ersa systems (provided via Belgian representative

Smans NV). After one day on board, Eric and

the ED&A team went to the Productronica trade

show in Munich to see the Ersa portfolio up close.

Shortly afterwards, they ordered a Hotflow 3/14e reflow

machine, a Versaflow 3/45 selective machine, a

Versaprint 2 stencil printer and an HR 600 Rework

System. Driven by Eric, ED&A went on to invest in a

top-class machine park with state-of-the-art soldering

systems, which, among other things, enabled full

inline X-ray inspection of every PCB and comprehensive

digitization of production with traceability down

to the component level.

“Of course, it was a big challenge to begin an electronics

manufacturing operation from scratch – we

actually had zero experience until we started production

in the fall of 2012,” Gert D´Handschotter recalls.

“Eric and his extensive experience in electronics

manufacturing were worth their weight in

gold for ED&A, it was an absolute win-win situation

for everyone involved – otherwise it would have been

very difficult to get such a production up and running,”

says Tom Berx, Ersa Sales Manager responsible

for Belgium, the Netherlands and Luxembourg at the

time. Eric retired in 2017, but he, together with the

ED&A team, had initiated a development that allowed

the company to grow to its current size. “The local

support from the Smans team, who is not far away

with its headquarters in Turnhout, was invaluable,

especially at the beginning,” says D´Handschotter.

For every machine ED&A has ordered, quality has always

been the most important factor. This is where

Eric´s expertise came in, as he had had the most experience

with high-quality machines. “Our goal with

our own production was to become the leader in

terms of production quality in Belgium. We succeeded

in this, and the Ersa systems we ordered initially

and subsequently have contributed significantly

to this,” D´Handschotter adds.

More flexibility, more speed

Since starting its own production line, the company

has reduced lead times by more than 60%

while increasing product quality by a factor of 10

(compared to its previously outsourced manufacturing

model). A few years after starting, the selective

Versaflow 3 machine was exchanged for the larger

Versaflow 4 model with four solder pots and two flux

“After ten years, we have gotten to know

each other well, have a stable business

partnership and know what our teams

and systems are capable of – we are

looking forward to the next decade and a

strong continued cooperation.”

Gert D´Handschotter, Managing Director, ED&A

heads (at that time, the first system of its kind in

Belgium). The highly modular character of the large

4/55 machine offers a great deal of freedom of configuration

and meets high process and qualitative

productivity standards. This results in reliably repeatable

solder joints, as well as complete documentation

of all individual process parameters.

EPP Europe » 11 | 2022 31

» PCB & ASSEMBLY

Another such system was installed at the end of

February. This time, the company invested in a

Versaflow 4/55 with six solder pots with y/z-variable

double crucible, power convection and automatic

nozzle activation for processing PCBs with a maximum

size of 508 x 508 mm. Just recently, a service

technician from Ersa was on site at the company for

three days to help to, as D´Handschotter put it,

“breathe even more flexibility and speed into the

machine – whether in soldering or through appropriate

programming.” The machine operators, who are

up to date on selective soldering technologies, took a

lot away from this visit, learning from a technician

who has accompanied the machine since the start of

its development and knows it inside out, down to the

smallest screw. “The ED&A team is really fit [regarding]

the process and continuously wants to get even

more out of the machine, which of course benefits

the customer in the end,” says D´Handschotter.

“Factory of the Future”

This is something that has also been recognized

externally by the “Factory of the Future” designation,

which ED&A received for the third time this year (as

well as in 2016 and 2019). The award, which stems

from an initiative by the Belgian technology association

Agoria & Sirris, evaluates “seven pillars of

transformation” every three years.

“Of course, we make sure that our colleagues and

engineers leave the manufacturing site once in a

while in order to stay up to date, or to take a look at

other productions,” says D´Handschotter. “For us, this

is a fundamental part of it. We cannot stand still if

we want to continue to be among the best in electronics

manufacturing in Belgium and beyond.

“A ‘factory of the future’ is not created by a great

machine park alone,” he adds. “This can only be realized

with the outstanding commitment of highly

motivated employees – and in cooperation with our

business partners at home and abroad.”

When ED&A now looks back, ten years later, to the

start of its own production, it is clear it has experienced

a massive surge in development. Whereas, at

that time, the company employed 25 to 30 people

and generated five million in sales, today’s workforce

numbers 110 and sales recently reached five times

that amount. The fact that it manufacturers its own

products means the company can respond to

changes more quickly and flexibly from the development

stage onwards. In the future, when new demands

pop up and a renewed SMD line investment is

on the cards once again, Ersa soldering systems will

“After ten years, we have gotten to know each

other well, have a stable business partnership and

know what our teams and systems are capable of –

we are looking forward to the next decade and a

strong continued cooperation,” says D´Handschotter.

New ventilation management system enables energy savings of up to 50%

MK Versuchsanlagen introduces further developed wet workbench

Frontal view of two MK wet workbenches with

different internals and connections

German special equipment manufacturer, MK Versuchsanlagen und

Laborbedarf has announced it has further developed its wet workbench.

The company says the applications of the wet workbench,

which it newly introduced two years ago, are extremely diverse. The

metal-free system is particularly suitable for use in the semiconductor

industry: substrate cleaning; and pre- and post-treatment of silicon

wafers, glass substrates and all other start and end products in these

fields.

The manufacturer says it developers have paid particular attention to

the intelligent ventilation management system, which enables energy

savings of up to 50 percent. Continuous monitoring of the wet workbench

ensures that the volume flow of the air introduced is automatically

adjusted. The control variables are controlled via dedicated PLC

modules. Possible control loops such as activity or particle monitoring

are individually defined and implemented, depending on the application.

Energy improvements for existing laboratories are also possible

Pressure-temperature sensor technology

ViscoTec debuts miniature flush pressure sensor

ViscoTec has announced the launch of the

world’s smallest flush pressure sensor

with a chemical – largely inert – pressure

membrane made of FFKM. The company

says the miniature sensor known as flowplus-SPT

M6 is also currently the only

sensor that achieves both pressure and

temperature measurement with an M6

thread as process connection and a sensor

body that is only 15.3 mm short.

The new sensor is able to measure the

pressures of the material to be dispensed

up to 40 bar at a temperature range from

5 to 50°C. It fits into the material outlet

of the manufacturer’s dispensing systems,

but can also be installed in other applications,

where its small design reduces

possible material losses due to dead

space-optimized components. Thanks to

its intuitive mechanics and short cable

length, integration into the company’s

own dispensers is quick and easy, so that

the sensor is immediately ready for process

data acquisition.

According to the company, the integrated

electronics convert the recorded pressures

and temperatures into an analog

voltage signal, which enables uncomplicated

and fast integration into control

systems such as a PLC. The low measurement

tolerance of only 2 % and the resulting

high measurement accuracy ensure

precise and, at the same time, simple

processing of the recorded measurement

data. In addition, possible cable breaks

can be detected via a drop in the pressure-dependent

voltage signal below 0.1 V

using the master-level control system.

“Thanks to its dust- and splash-proof design

(protection class IP54), the new sensor

operates confidently and reliably in

industrial environments even without the

attachment of further housing components,

the company said. The sensor body

is made of stainless steel and is therefore

largely resistant to the effects of every

conceivable material. Furthermore, the

measuring membrane made of FFKM is

significantly more resistant than conventional

membranes, which is reflected in

noticeably reduced maintenance and

spare parts costs. By means of a chemical

resistant, drag chain suitable sensor connection

cable, the smooth coupling with

ViscoTec controllers via a 4-pole M8

standard connection is possible.”

Dual-curing adhesive for medical device applications

Panacol develops first UV moisture-curing medical adhesive

the adhesive to cure while still in the dispensing needle. This offers the user

a wide process window. In addition, there are no blooming of frosting effects

on the plastics, which can occur when using cyanoacrylates.

Source: Panacol

The company says the UV acrylate is ideally suited for fixing

batteries on glucose sensors (corner bonding)

Industrial adhesives provider Panacol has developed

a new adhesive system certified for use in the medical

industry known as Vitralit UD 8050 MV F. The

company says that in addition to its primary curing –

UV crosslinking, the new adhesive also offers secondary

moisture post-curing. This means that components

in medical devices can be cured in a process-safe

manner and without thermal influence,

even if shadow zones are present in component cavities.

Two challenges commonly arise in medical applications

when bonding plastics or assembling PCBs

and FPCBs. Not every plastic is transparent, which

makes it difficult to cure UV adhesives in a processsafe

manner. In most cases, thermal post-curing is

relied upon. However, thermal curing often becomes

the second challenge. Not all electronic components

and plastics can be subjected to thermal stress. In

these cases, curing with heat is not a viable option.

Dual-curing

The primary curing of the new adhesive can be

carried out in seconds with UV or LED UV light. LED

curing units with a wavelength of 405 nm, such as

the LED Spot 100 IC from Hönle, are best suited here.

Secondary curing of the adhesive in the shadow

areas that are not reached by the UV/visible light

takes place through a moisture curing process.

Surface and atmospheric moisture react with the

adhesive to initiate a curing process. Unlike moisture

curing cyanoacrylates, the new adhesive can be processed

reliably because its primary curing is based on

UV crosslinking. Moisture in the air does not cause

Adhesion to different substrates

Vitralit 8050 MV F is certified according to ISO 10993–5/-10/-23 biocompatibility

testing. Since the dual-curing adhesive exhibits high adhesion to

many different substrates, it is the optimal solution for a wide variety of

bonding applications. The UV acrylate is ideally suited for fixing batteries

on glucose sensors (corner bonding). It can also be used as a glob top for

protecting SMD components. The adhesive will cure reliably and stress-free,

even in the shadow areas under the bonding wires. When used for structural

bonding, it can be applied between transparent and non-transparent

substrates. Bonding is accomplished in seconds with UV/visible light.

Shadowed areas will subsequently post-cure with moisture. Due to its high

ionic purity, the adhesive can be processed on metallized surfaces without

hesitation. For optical quality control of the bond, the material is additionally

equipped with fluorescent markers that can be excited with short-wave

light.

Increased test efficiency for automotive radar test chamber

Antenna test system gets new features

Global provider of test and measurement software, instruments

and systems Rohde & Schwarz has augmented its R&S

ATS1500C antenna test system with a new temperature test option

and a new feed antenna. The company says these additional

features enable temperature-controlled measurements in a

wide temperature range as well as parallel access to both polarizations,

increasing test efficiency and flexibility.

The movable R&S ATS1500C is a compact antenna test range

(CATR)-based chamber. It is designed to eliminate ghost targets

within the chamber during target simulation tests and includes

a highly accurate positioner for angular measurements.

The new temperature test option creates a temperature-controlled

enviroment for the radar under test and supports a wide

range from –40 °C to +85 °C. The heated or cooled air is provided

by an external thermal air stream system that supplies the

air to the temperature bubble mounted on the positioner. This

changes the temperature without affecting the chamber‘s

measurement performance. This feature makes it possible to

automate measurements at different temperatures without a

separate climatic chamber, which increases radar testing speed.

In addition, the new universal feed antenna, which supports 60

GHz to 90 GHz, can be added to the test chamber. The antenna

includes an orthomode transducer, which enables parallel access

to vertical and horizontal polarizations.

With these new options, developers can efficiently characterize

RF transmitters, calibrate antenna manifolds, measure antenna

patterns, test robustness against interference, check compliance

with regulations such as ETSI and FCC as well as plan testing

and calibration procedures for later mass production. The test

system is is used as a reference environment before porting the

procedures to a production tester.

Automatic x-ray inspection (AXI)

What are AXI systems

capable of in 2022?

In modern SMT production lines, AXI systems are mainly used for fully-automatic

inspection of hidden solder joints that are not visible to an AOI system. For anything

that requires close to one hundred percent optical inspection coverage,

there is no getting around the use of both an AOI and an AXI device, as the

authors of this article explain. So what exactly can modern AXI systems do?

And why are they so important?

Source: Göpel electronic

In modern SMT production lines, AXI systems are used for the fully-automatic inspection of hidden solder joints not visible to an AOI system

An AXI system is absolutely comparable

to an AOI system – only the

images are not as beautifully colourful,”

jokes Andreas Türk, product manager AXI at

Jena-based testing and inspections solutions

provider Göpel Electronic. The company’s

most recent AXI systems offer a

wide array of features including fast-scanning

image acquisition; inspection programme

creation; industry 4.0 integration;

and, thanks to the digital predictive maintenance

concept, self-monitoring. In addition,

the systems are all connected within

one network. If an anomaly is found, data

from the SPI, AOI and AXI systems is displayed

together on the verification station.

This helps operators track down the source

of the fault (see image overleaf).

Image acquisition tech

The newest AXI systems are able not

only to scan assemblies vertically (socalled

2D) or at an oblique angle (socalled

2.5D) in order to inspect solder

joints, but also using a technique called

3D x-ray inspection. This technology

allows for the inspection of solder joints in

several layers and, as such, offers the hig-

hest degree of defect detection and coverage.

In part, it is the combination of all

three image acquisition technologies that

provides the best inspection result. Since

3D technology generates a synthetic 3D

image using several obliquely-captured

images (in a process known as image reconstruction),

the image acquisition time

is longer than when using conventional 2D

or 2.5D technologies. 3D systems with

flat-panel detectors struggle here because

the time for stop-and-go movement of

the axes is significantly longer than the

actual time required for image acquisition.

40 EPP Europe » 11 | 2022


AXI text programme creationis similar to that of AOI. After the CAD data import, the image data sets required for tuning are recorded once. Further test

programme creation can then be carried out completely offline

"As a rule of thumb, when using eight oblique

images for a 3D image field, you can

expect an image acquisition time of about

3–5 seconds,“ explains Türk. Depending on

the image field size and the number of 3D

image fields required, this can add up, and

the acquisition time for a high-runner

product is too long. Göpel has come up

with a solution for this (see image below).

Cycle time reduction

The company‘s AXI system X Line 3D

relies on line detectors to keep image acquisition

time low. Several detectors take

2D, 2.5D and 3D X-ray images in parallel,

and in motion. This concept makes it

possible to inspect larger areas of the PCB

or complete multiple panels in 3D. In addition

to the image acquisition time, the

time for PCB handling, image processing

and optional MES export are included in

the total cycle time. For this reason, X

Line 3D systems have a three-chamber

principle. There are three PCBs in the system

at one time in inline mode. Once

image acquisition of the board has been

completed, it is immediately moved out

of the beam path into another chamber.

This is where post-processing takes place.

This reduces both total cycle time and

radiation exposure for the components

(see top two images overleaf).

Intelligent PCB handling

Over the years, the systems have also

become smarter in terms of PCB handling.

The PCBs that are inspected by AXI systems

vary in size, weight and friction coefficient,

among other things. In the past,

these differences were not taken into account

and PCBs were always transported

at the same belt speed. This can take up

valuable cycle time. For this reason, the X

Line 3D system belt transportation system

independently learns the optimal belt

speed by means of intelliFLOW. After an

automated teach-in process, the machine

stores the optimal transport parameters

specific to the inspection programme.

Usage-based maintenance

System downtime for maintenance

work is often problematic. At Göpel, systems

use a service & maintenance app

which creates usage-based maintenance

plans in advance and monitors the machine.

Self-diagnosis using predictive and

preventive maintenance management ensures

stable machine conditions and repeatable,

consistent performance. Every

key component of the machine is monitored

and a detailed maintenance summary

is generated. A preventive maintenance

plan reduces machine downtime

and therefore costs. On a practical level,

work no longer has to be carried out according

to scheduled maintenance cycles.

Instead, usage-related values (such as

kilometres travelled by the axes; pneumatic

strokes, and X-ray source radiation

hours) are monitored. These values are

given a warning and service threshold. If

the warning threshold is exceeded, preventive

maintenance can be initiated. The

app enables operators to simultaneously

monitor several machines. This makes

maintenance easier to plan and reduces

downtime.

The x-ray image chain

source and several line

printed circuit board is

moved in X and Y for

image acquisition.

The X-ray source is

mounted on a Z-axis.

The line detector

package is not moved



Three independent chambers in the system allow

image acquisition and post-processing (reconstruction,

saving measured values, MES and so on) to

take place in parallel- saving cycle time


Human-machine interaction

Human operators will certainly continue

to be required in 2022, as the enhanced

human-machine concept demonstrates.

Consisting of light bars integrated

into the system‘s external design in the

corners of the exterior cladding, these enable

operators to check the statuses of

various systems easily and quickly and

even from a distance. This helps operators

to react quickly and avoid a line stoppage.

In basic operating modes, static colours

are used to indicate if machine is checking,

waiting, is in service mode or has a

fault. In the event of an error, a distinction

is also made between the left and

right sides of the machine. If there is a

problem with the PCB infeed on the lefthand

side, it lights up red. A lack of material

in the infeed or a PCB jam in the

outfeed is also signalled using coloured

lights. In addition to static colours, certain

functions are also represented by

animations. The x-ray source warm-up is

indicated by a progress bar, for example.

The results of the last ten inspected assemblies

can also, for instance, be displayed

in statistical form (see image to

the left).


Time is money. The integrated light bars help to detect problems from a distance.

This helps to avoid downtime

software Pilot AXI as

Lower radiation exposure

Reducing the time that components are

exposed to radiation is becoming increasingly

important. The X Line 3D tries to

keep radiation exposure low in several

ways. Firstly, low-energy radiation components

that do not directly contribute to

imaging are reduced via filters in front of

the x-ray source. Secondly, the assembly

is transported out of the beam path onto

another belt module directly after the

image has been acquired in order to avoid

unnecessary radiation. Thirdly, the fact

that the image acquisition process has

very short exposure time minimises the

dwell time of the test specimen in the

beam path. This further reduces the components‘

radiation dose. The offline programming

2.5 & 3D DFT automation solution software

Siemens introduces multi-die software for 2.5D and 3D IC

design-for-test tasks

Siemens Digital Industries Software has

introduced the Tessent multi-die software

solution to help customers dramatically

speed up and simplify critical design-fortest

(DFT) tasks for next-generation integrated

circuits (ICs) based on 2.5D and 3D

architectures. The company says the

technology paves the way for mainstream

adoption of 3D ICs.

As demand for smaller, more power efficient

and higher performing ICs continues

to challenge the global IC design community,

next-generation devices increasingly

feature complex 2.5D and 3D architectures

that connect dies vertically (3D IC)

or side-by-side (2.5D) so that they behave

as a single device. However, these approaches

can present significant challenges

for IC test, since most legacy IC

test approaches are based on conventional

two-dimensional processes.

The company says its multi-die software

is the industry’s most comprehensive DFT

automation solution for highly complex

DFT tasks associated with 2.5D and 3D IC

designs. It works seamlessly with Tessent

TestKompress Streaming Scan Network

software and Tessent IJTAG software,

which optimize DFT test resources for

each block without concern for impacts

to the rest of the design, thereby stream-

lining DFT planning and implementation

for the 2.5D and 3D IC era. Using the new

software, IC design teams can rapidly

generate IEEE 1838 compliant hardware

featuring 2.5D and 3D IC architectures.

“IC design organizations are seeing dramatic

spikes in IC test complexity due to

the rapid adoption and deployment of designs

featuring densely packed dies in

2.5D and 3D devices,” said Ankur Gupta,

vice president and general manager of

the Tessent business unit for Siemens

Digital Industries Software. “With

the company explained

Siemens’ new [m]ulti-die solution, our

customers can be ready for the designs of

tomorrow, while slashing test implementation

effort and simultaneously optimizing

manufacturing test cost today.”

In addition to supporting comprehensive

test for 2.5D and 3D IC designs, the new

software solution can generate die-to-die

interconnect patterns and enable package

level test using the Boundary Scan

Description Language (BSDL).

“As the limits of traditional 2D IC design

approaches become increasingly clear

over time, more design teams are leveraging

the power, performance and form factor

advantages that 2.5D and 3D IC architectures

can deliver. But deploying these

advanced schemes in new design starts

without first establishing a DFT strategy

that acknowledges the inherent challenges

these architectures present can

raise costs and undermine aggressive

timelines,” said Laurie Balch, president

and research director for Pedestal Research.

“However, by evolving DFT technology

to keep pace with the rapid adoption

of multi-dimensional designs, EDA

vendors can play a key role in further enabling

global, mainstream adoption of

2.5D and 3D architectures.”

The company says its G3VM-MT MOSFET module offers maintenance-free operation and a simplified design that saves on board space

Solid-state modules for test applications

Minimizing leakage current with

T-circuit MOSFETs

There have long been concerns about the performance of solid-state relays – particularly

with regard to leakage current – when used in test applications. Gabriel Sikorjak, Technical

Sales Manager at Omron Electronic Components Europe explains how the newest solid-state

modules address these technical drawbacks, and advocates for their wider adoption.

MOSFETs are superior to reed relays in many respects.

Those continuing to use traditional relays

because of their low current leakage are missing the

benefits offered by alternative solid-state components.

Benefits of MOSFET relays

MOSFET relays deliver substantial benefits for test

equipment. They take up less space on boards, offer

faster switching times, and provide longer service life

than traditional reed relays. Many applications also

benefit from the lower power requirements, stable

on-resistance and better resistance to shock/vibration

they provide.

One of the key benefits of MOSFET relays is their

package size. Reed relay packages, placed in high

volumes on PCBs, require much more space. Increasing

demands from the semiconductor industry, test

equipment with a more advanced design, and higher

integration needs all affect the number of inspection

channels. All these extra requirements are transferred

into a larger number of switching components.

Using more compact MOSFET relays can thus

make a huge difference in terms of the amount of

board space utilised.

Then there is the question of reliability which, in

turn, translates into operating life. In test applications,

reed relays need to be regularly maintained.

Mechanical relays have generally been preferred in

the semiconductor industry (as well as for other test

equipment) – in part due to their isolation characteristics.

They do, however, have a shorter lifespan due

to abrasion of the contacts – which reduces equipment

durability over time. When used intensively,

mechanical relays need to be regularly replaced –

pushing up maintenance costs. Moreover, replacement

is necessary as soon as contact resistance goes

46 EPP Europe » 11 | 2022

G3VM-21MT reference design board testing result (DUT: FJH1100)

above a specified threshold, and this end-of-life moment

is not easy to predict or evaluate.

Alternative solid-state relays provide incomparable

electrical endurance and, when used with semiconductors,

do not suffer from mechanical contact wear.

There is thus no need for maintenance. Nonetheless,

there are still some performance trade-offs when

using these alternative relays. These are summarised

in the table on p. 56.

Leakage current – a barrier to

adoption?

Though used advantageously in many applications

in test equipment, MOSFET relays, like reed relays,

are stretched to their limits by increasingly demanding

test requirements. Despite boasting exceptional

reliability and tiny packages, to meet the needs of

the T&M industry, they must also deliver in terms of

performance. One of the most critical ratings for

semiconductor components is leakage current. During

DC parametric testing in automatic test equipment

(ATE), for example, minimizing leakage current

at the test line is a key factor to ensure accurate

measurement. Increasing drain-source voltage results

in increased leakage currents. This creates issues

with performance values. In circuit designs

where multiple lines are used, such as semiconductor

devices switching various DUTs and measurement

pins, MOSFET relays can reach their limit.

Are T-modules the solution?

Using T-circuit solid-state modules, however, it is

possible to address leakage current issues associated

with MOSFET relays. These modules are based on a

T-circuit built on three MOSFET pairs (as shown in

A T-circuit configuration

can dramatically

reduce leakage current

from MOSFET relays



EPP Europe » 11 | 2022 47



Isolation and insertion loss characteristics for G3VM-21MT

the diagram on p. 55). This design facilitates a higher

degree of control over leakage current. As shown in

the diagram, the leakage current flows to the ground

via a central joint when the relay is in the OFF position

and the primary line is open. The result is a substantially

lower level of leakage from the DUT than in

a standard circuit configuration.

The technical construction centres on MOSFET

pairs and enables effective control of the leakage

current, delivering minimal levels of pA or even fA.

The Omron G3VM-21MT module, for instance, specifies

a maximum leakage current less than 1pA at

V OFF

20V. Real-world values are usually lower by a

factor of ten. This indicates that T-circuit solid-state

modules represent a real alternative to conventional

solutions provided by reed relays in terms of

measurement performance.

Reference design is encouraging

A reference design is available to help design engineers

evaluate the impact of transitioning from

reed relays to these new T-circuit solid-state modules.

The aim of this is to show the value of MOSFET

relays in standard and T-circuit configurations and

reed relays on the same board under identical conditions.

Comparison of measurement accuracy can be

achieved across mature mechanical reed relays,

MOSFET relays and the MOSFET T-module.

The reference design highlights further differences

between these options and reveals the value of the

T-module. The results (shown in the graph on p.55)

prove that levels of leakage current from T-module

and reed relays are almost same as the reference

value from the DUT diode.

further positive characteristics at higher frequencies.

As shown in the diagram, results from the G3VM-

21MT confirm that a device with a high reliability,

small size and extremely low leakage can offer outstanding

RF performance. Its isolation performance

is less than –30dB at 1 GHz and the insertion loss is

more than –3dB (see graphs on p. 56).

The combination of benefits offered by MOSET relays

and mechanical relays mean the G3VM-MT

series is suited not only to ATE solutions, but is also

worth considering in other applications.

More than a component

With their T- circuit structure, Omron’s G3VM-MT

MOSFET modules demonstrate exceptionally low

leakage current, giving accurate measurements in all

types of test equipment. Their compact size (5mm x

3.75 mm x 2.7mm), achieved by incorporating the

MOSFETs into the module, allows for simpler PCB

board design owing to the elimination of crossovers

in PCB tracks and simplified wiring patterns. The device

is designed for surface mounting and offered in

SPST-NO form with ambient temperature ranges

above 100°C. New solutions include a high current

and high voltage model (as seen in the diagram and

graph above). Together, these specifications help

pave the way for wider use of T-circuit MOSFET relay

modules.

In summary, these modules offer maintenancefree

operation and a simplified design that saves

space on PCBs as well as great measurement performance:

contributing to industry progress and adding

value for the customer.
