摘要
This work presents an integrated experimental-numerical method to characterize, model, and experimentally study the properties of transfer molded power modules, considering two different thermal interface materials (TIMs). More specifically, a thermal grease and a phase change material are considered. The aim is to select the most reliable solution by making analytical characterization and power cycling tests on the modules equipped with the two kinds of TIMs. Then, further reliability study is accomplished, in order to estimate the lifetime of the power module equipped with the best TIM, that is the phase change one. Finally, a finite-element numerical model is developed and correlated with experimental data.
