This paper primarily investigated the effect of the different half-bridge module layouts for Hybrid electric vehicle (HEV/EV) on the reliability. Throughout the investigations, computational simulations were carried out on two different simplified half-bridge modules. The viscoplastic constitutive model Anand was employed in this case to calculate the plastic strain in the solder under thermal shock cycling loading. The scope of the research was broadened by selecting the various solder materials, which were subjected to power and thermal shock cycle loading. Hereby, the material data from SAC105, SAC205, SAC305, SAC405 and Sn36Pb2Ag were chosen and implemented in Ansys. To reduce the computational time, 2D models replaced the 3D models. Additionally, metallurgical investigations were carried out to highlight any additional effects, which influenced the joint reliability.
