Life Prediction of High-Cycle Fatigue in Aluminum Bonding Wires Under Power C…

In this paper, a 3-D finite-element (FE) model was established based on real test samples. Coupled electrothermal and thermal–mechanical FE analyses were conducted to analyze the mechanical behavior of bonding wire under cyclic power loading. The current crowding phenomenon may be improved by increasing the wire number. The junction temperature can be decreased by decreasing the joule heat f…
