EIPC Summer Conference in Munich to Discuss PCB Supply Chain Under the EU Chips Act

Estimated reading time: 2 minutes

A key attraction at EIPC’s Summer Conference, June 15-16 in Munich, will be the presentation by Stan Heltzel, Materials Engineer at the European Space Agency. Stan is responsible for qualification of Printed Circuit Board manufacturers and technology development, and is the convenor of working groups on space standardisation.

The subject of his presentation is supporting the PCB supply chain under the EU Chips Act. It will describe a white paper, recently issued by Eurospace, calling for the wide strengthening of PCB technology and its supply chain in all market segments. It focuses attention on the weak European PCB ecosystem causing unavailability in its own supply chain. Raw materials are almost exclusively manufactured outside Europe, the workforce is difficult to maintain, education institutes do not offer adequate training, and critical equipment and chemistry need to be imported, which hampers the availability of senior service personnel from these overseas companies.

Here is an abstract of Stan Heltzel’s paper:

“The number of PCB facilities in Europe has been continuously declining for several decades. Although in recent years the revenue appears to have stabilised, over a longer time span also this indicator follows a declining trend. About 60% of PCBs in Europe are imported, mostly from China. This dependency is most prevalent in volume markets, but also NewSpace equipment integrators are occasionally sourcing PCBs overseas, motivated by lower cost, shorter lead-time and in some cases a better capability. Qualification schemes and contractual conditions ensure local sourcing of PCBs in the high-reliability market segments of space and defence. For this low volume, high mix industry the most critical impact is an indirect one: the weak European PCB ecosystem causes unavailability in its own supply chain. Raw materials are almost exclusively manufactured outside Europe, the workforce is difficult to maintain, education institutes do not offer adequate training, and critical equipment and chemistry need to be imported, which hampers the availability of senior service personnel from these overseas companies.

The end of a globalised market and the consequential reshoring has been initiated by the US-Chinese trade conflict and further deepened by the supply chain disruptions during the pandemic and the Ukrainian war. There is much excitement about the development of local chips technology and its ecosystem. The European Chips Act provides development opportunities from foundry to OSAT. But the act does not analyse the ecosystem beyond back-end packaging and is not inclusive of system level packaging, i.e. PCB technology and assembly. The global electronics industry struggles with the ‘hidden reliability treat’ in microvias. Yet it remains difficult to obtain development funds. This has caused critical failure of assembled flight electronics in several ESA projects. A state-of-the-art FPGA was developed and space qualified. But the routing of this part required microvias, which appeared to be failing. Not only the malfunctioning modules were scrapped, but also other - working - modules from batches that were affected by this microvia weakness. This presentation will describe a white paper, recently issued by Eurospace, calling for the wide strengthening of PCB technology and its supply chain in all market segments.”
