The effect of electrical current on the microstructure, the tensile properties and vibration deformation mechanisms of the Sn-9Zn-1Cu leadfree solder were examined in this study. Results showed that Zn-rich phase, Sn-Zn eutectic, Cu5Zn8 intermetallic compounds and proeutectic Sn-rich phase existed in the matrix of a Sn-9Zn-1Cu specimen. An electrical current flowing for a short duration was able to improve the tensile strength of the solder alloy. But prolonging the duration more than 7 hours… CONTINUE READING
