Abstract

In the present study, a new constitutive model for eutectic solders (63Sn37Pb) is proposed. Grain sizes and phase sizes are considered as the coarsening is one of main reasons to failure of solder joints. The present model has been developed based on the combination of grain boundary sliding and matrix dislocation deformation mechanisms in order to describe a thermo-mechanical behavior of eutectic solders. Internal stress tensors are also introduced to describe the transient behaviors during the tensile test and first stage creep. A series of tensile tests, creep and creep recover tests were conducted at temperature range from-10 to 100°C. The specimens with two different phase sizes were tested. Good agreements were obtained between the experimental results and the model.
