PROJECT TITLE :
Lifetime Evaluation of Nanoscale Silver Sintered Power Modules for Automotive Application Based on Experiments and Finite-Element Modeling
The thermomechanical behavior of power modules has been invariably a difficulty with regard to reliability improvement. Silver sintering technology is one amongst the few alternatives for die attachment, which might bring a longer operating lifetime. Finite-element modeling (FEM) is as vital as the experimental development for such a new technology. In this paper, we gift a lifetime analysis approach for power modules utilized in automotive applications due to thermal characterizations, thermal ageing, and thermomechanical FEM analyses. A lower coefficient of thermal expansion mismatch with the silver sintering technology as compared with soldering will increase the thermomechanical resistance to thermal swings (regarding six times). The FEM analyses of the buildup of the strain energy density help perceive and find the high-stress space in a very silver-sintered power module. Finally, this paper leads us to estimate the operating lifetime of silver-sintered assemblies for a specific mission profile by considering the thermomechanical behavior.
