Abstract

The microstructure, adhesion strength and conductivity of electroplated Sn-Cu Films on Alloy42 lead Frame were measured for comparison. In the case of electroplated 90Sn10Cu, 99Sn1Cu, Cu$\sub$10/Sn$_3$Phase was formed and Ni$_3$Sn$_2$Phase was formed after 200$^{\circ}C$, 30min annealing. In the case of electroplated 99Sn1Cu, Cu$\sub$10/Sn, Ni$_3$Sn phases were formed and Ni$_3$Sn$_4$, Ni$_3$Sn$_4$phases were formed after 200$^{\circ}C$, 30min annealing. 90Sn10Cu film was measured better uniformity, adhesion strength and conductivity than 99Sn1Cu.
