PCB + ASSEMBLY PRODUCT
PCB + ASSEMBLY PRODUCT UPDATES Robotically controlled dry storage management systems Moisture control specialist Super Dry Totech’s latest generation of robotically automated component storage systems will be available at November’s productronica. The company’s Dry Tower incorporates complete moisture management, floor life reset and traceability of MSL components, in addition to optimising the storage demands of different sized reels and trays, operator-free. Businesses are striving for more flexible automation and digitalization of processes, symbolized by ever expanding Industry 4.0 initiatives including sophisticated track and trace logistics throughout the entire supply chain. Relentless attention to the elimination of routine manual tasks and higher efficiencies within existing shop floor constraints is a fundamental and essential element of competitiveness, survival, and growth. The company’s robotically controlled Dry Storage management systems have demonstrated their ability to serve these needs and greatly aid making the vision of mass cus- tomization in Smart Factories a reality. The next generation of the Dry Tower is now expanding its pinpoint automation beyond the four walls of the automated, environmentally controlled warehouse to provide the automated delivery of goods directly to assembly lines in a more flexible manner. Fixed conveyors and operators are being replaced with a variety of more cost saving, and quickly changeable methods that can utilize existing factory layouts. Goods incoming, feeder preparation, line prep and replenishment, emergency components, delivery to support stations and return to floor life protective storage are examples of essential manufacturing process flow events. The Dry Towers’ Autonomous Indoor Vehicle (AIV) systems, developed and integrated by Asys, accomplishes these tasks, further reducing the need for operators in those areas of the manufacturing process. At the same time, they provide a flexible buffering of product flow, ensuring that feeding The automated logistics systems feed assembly lines operator free. production can be a priority, eliminating bottlenecks and accelerating the smooth logistics flow. At the show, Asys will showcase solutions for the automation of the entire material flow in a modern electronic manufacturing facility. The company has developed a modular, expandable logistics concept, which consists of three main components: Centralized Component Bearing, Autonomous Indoor Vehicles (AIV) and Material Stations. All system components communicate with each other via the company’s software solution Pulse and pass on the respective orders. productronica, Booth A3.277 www.superdry-totech.com/dry-tower-system; www.asys.de Source: Super Dry Totech 50 EPP EUROPE November 2017

As a Zestron will be exhibiting cleaning machines at productronica. result, trade show visitors who are looking for a new cleaning machine can compare different, innovative, and proven technologies directly on site. The company’s process engineers and representatives from equipment manufacturers are available for questions regarding the features, as well as, the optimally adapted cleaning agents. Further trade fair highlights are the pH neutral PCB cleaning agent Vigon N 640, providing excellent cleaning performance on the latest fluxes in specific batch systems, as well as the single-phase stencil cleaning agent Hydron SC 300, designed to effectively remove SMT adhesives without leaving streaks after drying. productronica, Booth A2.359 www.zestron.com POWERFUL SPRINGS FROM FLEXIBLE MANUFACTURING THE PRODUCT RANGE EVERYTHING FOR YOUR SUCCESS » CONSTANT FORCE SPRINGS » INDUCTION COILS Launching of DMS for UV LED applications Thermal management innovator, Cambridge Nanotherm, announces the launch of Nanotherm DMS, a direct-metallised singlesided thermal management solution that addresses the challenges created by UV LED modules. Ultraviolet (UV) light has key applications for curing resins and inks (UVA) and for disinfection and sterilisation (UVC). LED technology has transformed the industry by enabling smaller, more cost-effective and robust devices that have opened up previously inaccessible applications. UVA LEDs are rapidly displacing traditional UV lamps in the industrial printing industry, speeding up print times and reducing cost, while UVC LEDs open up applications like portable sterilisation units that can provide millions with clean drinking water, or let you sterilise your toothbrush when you’re camping. The UVC market in particular is on the cusp of meteoric growth. However, UV LEDs present a significant thermal challenge. UVC LEDs often only convert 5 % of the power put in to photons. The remainder must be conducted away as heat via the base of the LED to a thermally conductive PCB to avoid the LED die overheating. As shorter wavelengths of UV light degrade organic material the choice of PCB is often limited to inorganic materials, discounting cost-effective metal-clad PCBs (MCPCBs) that rely on an organic epoxy based dielectric layer. Ceramics such as aluminium oxide (Al 2 O 3 ) or aluminium nitride (AIN) are used, but they present a conundrum to LED designers — low-performance but cost-effective alumina (25 W/mK), or high-performance but expensive aluminium nitride (140–170 W/mK). There is another issue with ceramic. It’s brittle and prone to cracking, far from ideal for the new wave of portable applications and equally an issue for industrial applications — overtighten a screw and the module PCB will fracture. The company has developed DMS to address these issues. It combines the robustness and manufacturability of aluminium with the high thermal performance of AIN and as it undergoes thin-film processing, it’s entirely inorganic. The company’s direct metallised single-sided PCB (Nanotherm DMS) uses an extensively patented electro-chemical oxidation (ECO) process to convert the surface of aluminium into an alumina dielectric layer. This nanoceramic alumina has a thermal conductivity of 7.2 W/mK which, coupled with being just tens of microns thick and using a direct metallisation process, gives a composite thermal performance of 152 W/mK. While this is slightly inferior to the very best and most expensive AIN substrates, the mechanical robustness of the company metal board permits better approaches to mounting so measured system performance exceeds that of aluminium nitride. productronica, Booth B3.176 www.camnano.com Constant force springs » Practically linear force progression and low hysteresis » Solutions for small installation spaces Induction coils » Single or double-wound body with stripped and tinned ends, as well as » With stampings and bonded core EMPLOYEES 115 Bohnert GmbH Weilerstraße 33 78739 Hardt Tel. +49 (0) 7422.27 09-0 info@bohnert-federn.de 3 MILLION SPRINGS DAILY 40 YEARS OF EXPERIENCE www.bohnert-federn.de EPP EUROPE November 2017 51
