Abstract :
In this paper, the vibration durability of SAC305 solder interconnects of Heat-sink Very-thin Quad Flat-pack No-leads (HVQFN) assemblies is investigated by accelerated stress testing and Physics-of-Failure (PoF) simulations, under various types of vibration excitation. In future work, these results will be used to develop PoF models for vibration fatigue durability of Pb-free SAC305 solder interconnects and to extract model constants from test data.
