minimal energy principle and finite element method were employed to develop solder joint shapes evolving model of PBGA.And three dimensional solder joint shapes of PBGA was predicted and analyzed.Comparisons were made between results predicted by the current model here and experimental measurements and those generated by mathematical analysis model at abroad.
