PCB + ASSEMBLY Swiss electronic manufacturer implements an all-around process optimization 3-phase project for efficiency improvement and process optimization In order to be able to secure medium to long term jobs in Switzerland, processes have to be constantly checked and further optimized and automated. A smart and innovative investment policy forms the basis for a successful growth. Process optimization is key for success, as is the case for the company, EPH Electronics AG from Diessenhofen. Since 2015, they have devoted their efforts to go towards Industry 4.0 and optimize their process by modernizing their production. As part of the first phase, the MY200-DX10 placement system from Mycronic, as well as, the reconfiguration of the existing systems were obtained.

EPH Electronics AG was founded in 1980 in Feuerthalen. Today, the Swiss electronic production company is devoted to their customers with around 70 employees in 10,000 m 2 . By having the state-of-the-art machinery, combined with a qualified and motivated production and development team, enables the provision of services over the complete life cycle of a product. This starts with the creation of concepts, the development and prototyping, testing phase, production launch and the ramp-up, mass production, to the end-of-product life phase. As an EMS company, they go beyond just production services, from contract assembly to the production of complete assemblies and devices. In doing so, the company relies on long-term relationships with customers and suppliers. This is also the case with Mycronic, a company that develops solutions for the assembly of electronic components with its MY200 platform. Their product portfolio, including the unique jet and dispenser platform MY600, the automatic and intelligent material handling, and the latest generation SMT Tower 6150 series, provides a complete and powerful production solution. The benchmark of productivity As business started to increase, EPH recognized that not only was their tight space no longer practical, but also all systems in the SMT department were from different manufacturers, making them incompatible with one another. They knew they had to find a solution to these specific issues. It was also found that there wasn’t an effi- Source: EPP Europe 28 EPP EUROPE November 2017

The new equipment and the SMT tower was put into place in Diessenhofen in the beginning of 2016.

Early 2015, an analysis was started, in order to determine exactly where the performance gaps were located and figure out how to optimize the process. EPH defined their goal as: “Maximum efficiency with the highest possible flexibility”. More specifically, this meant to: • increase efficiency • optimize the use of space • have compatibility within systems • have backup solution for machine failures • automate material handling • increase automation in the direction of Industry 4.0 The actual state had to be determined first, to then be able to define what it should be like, in order to make definite changes. “We immediately recognized,” says the Quality and Lean manager, Ulf Schmidt, “that the problem was not in the assembly house, but actually the setup changeover, so this is where we started out. We also discovered that it came from missing components at machine downtime, so the material flow was not optimal.” Another issue that was found was the arrangement of the placement machines and the different level of hardware and software. With the aim of obtaining as much as possible from a single source, the company investigated the different possibilities at the SMT show in Nuremberg and productronica in 2015. This is where Mycronic was able to provide the required solutions. The 6150er series Material Tower and the software MyPLan from Mycronic was exactly the missing link between the warehouse and production that was needed. Together, both companies developed and implemented a concept, which was divided into 3 separate phases. In the first phase, the outdated system of the second manufacturer was removed. In its place, a Mycronic MY200-DX10 placement system was obtained, as well as, a plan to reconfigure the other existing systems. All units were brought under the same software and hardware system. The conversion was planned in such a way that never more than one third of the capacity was blocked at one time. In the second phase, the Material Tower and the associated software for material management were installed and put into operation. Around the same time, the material flow was updated, meaning the automated external setup station was set up. This update included the Mycronic PRM 2.0 software, which enabled the monitoring of outgoing material on the equipment, and is displayed in real time on a large screen for all the lines to see. During this time, a user meeting was organized, at the office of Mycronic in Unterhaching, Germany, to find out about new trends, participate in lectures on topics as in Industry 4.0, and have the opportunity for other users of Mycronic systems to interact with each other and share ideas. Developers also took into account requests from the users for future developments. “For us as customers, the user meeting was a well-rounded win-win situation for all involved,” says Ulf Schmidt. Through the close cooperation with Mycronic and the effect that, at the time, Mycronic had with their new software tools that aimed at optimizing production, the EPH team used a part of the Mycronic 360 ° approach. This 360 ° standard approach is used worldwide to analyze the efficiency and performance of a SMT manufacturing process. By implementing this approach, further optimization could be discovered. Due to a lag in the housing databases of the placement systems, which has grown over the years, Mycronic explored what benefits could come just from revising the database. Maik Karras, the Service Engineer and Process Optimization Expert of Mycronic, immediately knew where to start. EPP EUROPE November 2017 29
