How OEMs overcome structural dependencies in
electronics manufacturing and build truly resilient sourcing networks.
It is one of the most persistent beliefs in the electronics industry: a supply chain for electronic assembly manufacturing fully secured within Europe is unrealistic. Too dependent on Asian semiconductors, too concentrated the printed circuit board production, too limited the European component capacities.
This assessment is not fundamentally wrong – but it draws the wrong conclusions. Because nobody claims that an electronics supply chain can be completely restricted to Europe today.
The decisive question is a different one: how do you build a supply chain in such a way that it remains stable even when individual supply routes fail?
Still, more than eight out of ten German industrial companies report that supply chain bottlenecks disrupt their operations. At the same time, recent studies show that companies that have actively diversified their supply chains are significantly less affected by production halts.
The difference does not lie in the sector or the product – it lies in the structure of the supply architecture.
Today, OEMs are increasingly being questioned by customers, auditors, and regulators regarding the origin of their components – from the wafer to the assembled board. Anyone who cannot provide this transparency loses orders. Regardless of the unit price.
The structural problem of many supply chains in electronics manufacturing is not a lack of capacity – it is a lack of redundancy. Critical components from a single supplier, printed circuit boards from a single region, semiconductors from a single source.
If one of these points fails – due to geopolitical tensions, natural disasters, allocations, or insolvencies – series production comes to a standstill. Leading research institutes have emphasized for years that methodically structured scenario planning and modular, reconfigurable supply chains are among the most effective levers for proactively managing supply risks.
The key does not lie in the lowest purchasing price, but in the structural resilience of the entire supply chain.
A resilient supply chain for electronics manufacturing is not based on the principle of "everything from Europe" – but on the principle of "no critical material from only one source." In practice, this means: European suppliers are preferred and developed wherever possible – for shorter transport routes, better transparency, easier ESG documentation, and lower capital commitment.
For components and materials that are structurally unavailable in Europe – such as certain semiconductors, specialized passive components, or raw materials – alternative suppliers on different continents are deliberately qualified and maintained in parallel. Not as an emergency solution, but as a structural component of the supply architecture.
Multi-sourcing strategies with regional suppliers, flexible reconfigurable networks with regional buffers, and the buildup of safety stocks for critical components are cross-industry recognized as the most effective measures against supply chain disruptions – current analyses by McKinsey, Deloitte, and the Fraunhofer IML confirm this equally.
EMS Strategy Group analyzes the OEM's bill of materials (BOM) for critical material dependencies – single-source components, volatile lead times, obsolescence risks, and geopolitically exposed supply paths.
Based on this, a supply architecture is developed that prioritizes European sources while simultaneously securing strategic alternative paths on other continents.
The result is not a theoretical risk analysis. It is an operational material architecture that prevents a supply failure from stopping series production – before it even occurs.
