This paper presents the design and reliability assessments of a novel power semiconductor module platform for the automotive powertrain. Solder-free interconnects enable superior reliability meeting future automotive requirements. Modules with heavy Cu wire bonding on sintered top plates show a strongly improved power cycling lifetime compared to standard Al wire bonding. However, new failure modes are observed for the fully sintered devices.
