Technically advanced PCBs are indispensable for high-end electronics applications. High-layer multilayer PCBs or rigid-flex PCBs are used in complex electronic control systems, sensor technology, communication systems, and power electronics. In Europe, there are a handful of manufacturers that specialize in such highly complex multilayer PCBs and are also capable of producing prototype quantities (50–100 pieces) in the highest quality. This article presents five of the most renowned suppliers in Germany and Austria who have proven expertise in technically demanding applications such as automotive, industrial electronics, aerospace, and medical technology and are certified accordingly (e.g., IATF 16949, ISO 9001).
