Reliability modeling for aged SAC305 solder joints cycled ...

Jan 01, 2020· The cyclic change in the environmental temperature is one of the most common issues that is associated with the solder joint fatigue life. These changes can create alternating shear stress on the solder joints due to the mismatch in the coefficients of thermal expansion between the substrate and the electronic component materials.
