TRACE-PCB – Greater Security for Global Electronics Supply Chains

Tampering, product counterfeiting, and the undetected replacement of electronic components pose ever-greater challenges to global electronics supply chains. The TRACE-PCB research project is developing an innovative technology platform that enables printed circuit boards (PCBs) to be uniquely identified, securely authenticated, and traced throughout their entire lifecycle.

To achieve this, the project utilizes microstructural variations that arise during PCB manufacturing. These variations form a unique, physically unclonable “fingerprint” (Physical Unclonable Key, PUK), which can be read contactlessly and converted into a unique digital identity using intelligent image processing.
The technology can be integrated directly into existing manufacturing processes without the need for additional security chips, QR codes, or RFID tags. This results in a cost-effective, scalable, and easily implementable solution that sustainably improves the security of modern electronics supply chains.

The project is being carried out by a consortium consisting of Bischoff Elektronik GmbH, Schmalkalden University of Applied Sciences, and incowia GmbH.
TRACE-PCB is co-financed by the European Regional Development Fund (ERDF) as part of the FTI-Thüringen TECHNOLOGIE program. The goal is to develop innovative technologies, sustainably strengthen Thuringia as a hub for innovation, and enhance the security of European electronics supply chains in the face of international competition.
