This paper is emphasized on the compression behavior of Sn-3Ag-0.5Cu (SAC305) and Sn-37Pb at elevated temperatures. The effect of temperature for Sn-3Ag-0.5Cu (SAC305) and Sn-37Pb alloys was also discussed. The Quasi-static compression test was also conducted by using the SHIMAZDU AG-X material testing machine and the loading rare was chosen to be 1.67×10-3 s-1 and 1.67×10-4 s-1. Moreover, heating oven was utilized to control the specific temperatures (approximately 30°C, 60°C and 90°C), and the corresponding K-type digital thermometer was used to record the temperature during the tests. According to the several strain-rate ranges studied, the limited strain-rate hardening effect for these alloys studied were reported. In addition, the effect of elevated temperature on the solder material softening was also presented. The test determined saturation stresses were also presented for both Sn-3Ag-0.5Cu (SAC305) and Sn-37Pb solders, and relationship among the saturation stresses, strain-rate hardening and material soften is discussed.
