Thermal fatigue behavior of J-lead solder joints - Semantic Scholar
Web• Developed design guidelines for 2.5D ASIC package with mitigated warpage and enhanced thermo-mechanical reliability by FEA simulation. • … Solder damage models take a physics-of-failure based approach by relating a physical parameter that is a critical measure of the damage mechanism process (i.e. inelastic strain range or dissipated strain energy density) to cycles to failure. The relationship between the physical parameter and cycles to failure typically takes on a power law or modified power law relationship with material dependent model constants. These model constants are fit from experimental test… fnsf fusion
