Built-in Thermal Test as a Pre-Integrated Architecture

Abstract

Built-in Thermal Test is a key method to assure reliable operation during the product life time. Pre-integrated architecture is a design concept for cyber-physical systems to reduce R&D efforts. In this work the built-in thermal test methodology was adapted to this design concept and its operation was demonstrated in a chemical flow-reaction system where the reactor’s thermal interface was qualified. The demonstrational measurements showed that the system was able to distinguish different reactor assemblies with intentionally degraded thermal interfaces with a resolution of 0.05 K/W.
