Abstract

Properties of body-centered tetragonal β-Sn are highly anisotropic. The crystal orientation of the β-Sn has a marked effect on the stress state in the SnAgCu solder joints. A finite element analysis has been performed of the thermal cycling of the SnAgCu solder and solder joints. Significant amounts of stresses at the solder/Cu interface and in the plane of the grain boundary was found. The best Sn grain orientation is perpendicular to the solder/Cu interface.
