Abstract:
Power electronics demand high reliability and lifetime to prevent high costs and downtimes due to unplanned maintenance. This paper uses a transient thermal FE simulation to analyze the thermal behavior of an IGBT power converter module. Different failure modes are in the focus of investigation: die attach constriction, wire bond lift-off and solder as well as thermal grease degradation. The simulation is optimized with the help of thermal impedance measurements of a device in power cycling. With the help of FE simulation different failure modes are possible to identify in the structure function. Extended use of these results is presented.
