... GPa, respectively. Compared to the Cu 41 Sn 11 solder joint, the shear strength of full α (Cu) solder joint decreased dramatically due to the relatively low hardness of α (Cu) and the generation of voids, but the strain rate sensitivity index increased significantly. After the shear test, Cu 41 Sn...
