This paper presents a method to obtain the effects of small ΔTj on the power modules so that we can enhance the reliability and lifetime model. Bonding wire fatigue and die-attach solder fatigue have been identified as one of the main root causes of power electronic module failures. Power cycling rig is designed to obtain the process of power module failure and account for the thermal fatigue life...
