Comparison between finite-element and analytical calculations for the lifetime estimation of bond wires in IGBT modules

Coffin-Manson fatigue law based lifetime estimations of aluminum bond wires in IGBT modules under field conditions were performed. The models were calibrated with fatigue data obtained from accelerated lifetime tests and plastic strain computations corresponding to test conditions. The calibrated laws were then used to predict the bond wire lifetime under field conditions. To evaluate the influence of the plastic strain calculations, finite-element and analytical computations were performed and the resulting lifetimes compared.
