WebMechanical Behavior Evolution of SAC305 Lead Free Solder Joints under Thermal Cycling Abstract: Solder joints in electronic packages are frequently exposed to thermal cycling environment. Such exposures can occur in real life application as well as in accelerated thermal cycling tests used for the fatigue behavior characterization. Weband CTE of SAC105, SAC305, and SAC405 were measured on actual solder joints at different tem-peratures. While the properties of Sn are known to be anisotropic,21 this …
