摘要: In this paper we verified the submodeling technique applied in thermomechanical reliability assessment of a flip-chip BGA under accelerated thermal cycling test conditions. Since steady-state creep model was implemented for solder bump to better represent its realistic mechanical behavior, procedures developed specifically path-dependent problems were considered. A detailed global built up verify solutions. This also served as benchmark examine solution discrepancies caused by different simplifications model.
