PCB + ASSEMBLY Focusing on process optimization Process optimization is used to improve efficiency and effectiveness of existing processes, as well as, the use of necessary resources that need to be continuously updated. It is based on a process oriented approach to the entire operational systems. When a Lean Manager is not specifically set in place, the system supplier and its 360 ° standard approach will help in this regard. With the conversion to external setup, EPH has already seen a significant benefit of almost 25 %. By investing in an additional placement machine and a new line configuration, an optimization was achieved by a total of 42 %. With a combination of the comprehensive data optimization, a further 20 % was achieved. According to the team, “The percentages and figures were easily detectable for +++ Video-Interview +++ Within 3 phases, the Swiss company successfully optimized their process. Readers can find the video here, patible with each other. Redundancy is also available, which means that one product can be produced on all three lines. Two of the lines are designed for extra-large PCBs, while the third line is for smaller circuit boards with a higher component density. Although the Material Tower from Mycronic stands separately, it is planned to be relocated in the near future, bringing the tower directly into the lines. This will not only create an even higher material stability, but it will also avoid long distances of going back and forth, and therefore save time. All targets for the optimization values that were calculated before the start of the project were almost exactly reached. The program continually screens to make sure whether or not the goal has been reached and notices which direction trends are going. Since the beginning of this year, the Shop Floor Management implemented daily targets to constantly monitor the process. However, transitioning towards Lean Management is a constant checking process, as Ulf Schmidt emphasized, “We can clearly see differences in our evaluation curves when our attention is focused on other projects. But in terms of potential for optimization, we are on the right track.” The third phase is currently being implemented. This includes an expansion of capacity with a Mycronic MY200-HX 10 that will complement an existing line, with the hopes of accomplishing further potential of almost 20 %.

Using the software tools, MYPlan (which generates reports indicating which component type is in which feeder load) and MYCenter, for the organization of the carrier database, a comprehensive functional material flow could be ensured. The carriers are matched with the component types specified by MYPlan from the warehouse, so that the external set-up is now fully automated and secure. An important aspect to think about is the frequent changeovers of service providers with batch sizes from 1 to 15,000. The typical size is 500 to 5,000. The conversion and optimization not only brought an increase in efficiency, but the backup solution is now secure, in the event of a complete failure. All systems in the three SMT lines are now com- Source: Doris Jetter Zusammenfassung Eine kluge und innovative Investitionspolitik bildet die Grundlage für eine erfolgreiche Wachstumspolitik. So ist Prozessoptimierung eines der Schlüsselworte zum Erfolg, wie sich deutlich am Beispiel der EPH Electronics aus Diessenhofen zeigt, die sich seit 2015 intensiv gemeinsam mit Mycronic der Prozessoptimierung und Modernisierung ihrer Fertigung in Richtung Industrie 4.0 widmet. Résumé Une stratégie d’investissement intelligente et innovante est la base d’une stratégie de croissance efficace. L‘optimisation des processus est l‘un des mots clés du succès, comme on le voit avec l‘EPH Electronics de Diessenhofen, qui travaille intensément avec Mycronic depuis 2015 sur l‘optimisation des processus et la modernisation de leur fabrication dans la direction de l‘Industrie 4.0. Резюме Разумная и инновационная инвестиционная политика является основой успешного роста предприятия. Поэтому оптимизация процессов является одним из ключевых элементов успеха, что наглядно можно проследить на примере компании EPH Electronics из г. Диссенхофен, которая с 2015 г. в активном сотрудничестве с компанией Mycronic посвятила свою деятельность оптимизации процессов и модернизации своего производства в соответствии со стандартами Индустрии 4.0. 30 EPP EUROPE November 2017

PCB + ASSEMBLY Efficient light emitting diodes for the automotive industry, medical technology, and power electronics Perfect lighting management thanks to modern LED technology LEDs are changing the world of light: they consume considerably less energy than conventional light bulbs and at the same time have a longer service life, are more economical, and do not contain any highly toxic substances, such as mercury. In the field of high-performance lamps, the automotive industry was one of the first sectors to get involved with this trend and at the end of the 1990s, was already installing headlight systems equipped with LEDs (light emitting diodes) into cars. Anna-Katharina Peuker, Public Relations, Rehm Thermal Systems GmbH In order to assure that this new lighting technology functions flawlessly, heat generated by the LEDs must be reliably dissipated. This is where Asetronics comes in. The company located in Bern, Switzerland, produces and develops modern electronics for LEDs and is continuously researching strategies targeted at improving temperature management. The company has been successful in manufacturing light modules for the automotive industry. Their product range also includes street lamps and railway illumination, work lamps for industry, laboratories and offices, as well as, lamps for surgery and examinations in the field of medical technology – all on the basis of LEDs. Quality connects: Swiss precision united with German machinery manufacturing Until 2004, the company belonged to the production division of telecommunications manufacturer, Ascom. In 2006, they successfully launched independent operations with its first LED applications involving chip-on-board technology. These applications are used in the brake lights, blinkers, fog lights, and daytime running lamps of vehicles produced by renowned automobile manufacturers. Asetronics has since experienced strong growth and in the meantime employs 190 persons. Roughly 60 % of the company’s annual turnover is generated alone with LED light modules for automotive headlights. The Swiss enterprise cooperates with suppliers of wellknown brand names, such as Audi, BMW, Daimler, and Porsche. Whereas only premium automobiles were equipped with LED light a number of years ago, cars without this modern lighting technology are now rare. Pressure is rising along with unbelievable growth of the industry sector. The company produces roughly 250 million SMD components each year. They are continuously expanding their product range and production capacity, maintaining high levels of quality, and conducting research targeted towards optimizing their technology. The company relies upon diversified know-how in order to make successful progress in this respect. And this means that they not only assemble and process the light modules, they also manufacture the metal-core PCBs for the LEDs. This makes it possible to optimize heat management and to continue to improve it by means of an in-house R&D. “In extreme cases, inadequate temperature management can result in irreversible damage or destruction of the LED and the PCB. Light emitting diodes radiate light to the front and heat to the back, The VisionXP+ Vac from Rehm Thermal Systems. which has to be dissipated from the chip as quickly as possible. At temperatures of greater than 150 °C, the sensitive diode degenerates”, explains Georg Schafer, the company’s Head of Turnkey Electronics. There’s a small thermal resistor between the component and the PCB, as well as between the PCB and the heat sink, in order to ensure ideal temperature management. Heat at the bottom can be removed and dissipated via the heat sink with the help of microvias. The heat sink functions in turn via the metal-core PCB with its extremely thin layer made of insulation material, which ideally spreads and dissipates the heat. This is particularly important due to the ever increasing levels of miniaturization. Where the production of sensitive electronic components is concerned, Asetronics relies on top quality systems engineering from Germany. Over the last three years, in order to reduce maintenance costs and manufacture more efficiently, the company has entirely switched over to reflow soldering systems from Rehm Thermal Systems. Three VisionXP+ convection soldering systems are currently being used in production. The team standing in front of a VisionXP+ Vac at Asetronics’ production facility.
