Abstract:
Solid-state power modules are subjected to harsh environmental and operational loads. Identifying the potential weak-links and dominant failure mechanisms is very critical to designing reliable power modules. This paper presents the PoF (Physics of Failure) based approach to determine the stresses/strains and the damage arising due to the thermo-mechanical loads in some of the critical failure sites identified in typical power modules.
