Sn?58Bi alloys with different Ce contents were fabricated by vacuum smelting and casting. The microstructure, phase composition and properties of the alloys were investigated. The influence of Ce on shear strength of Sn?58Bi/Cu solder joints was emphasized. The results showed that the Sn?58Bi eutectic microstructure were refined, and the melting point and melting range were less affected by Ce addition. The wettability of Sn?58Bi alloys reduced when the Ce content increased, the shear strength was maximum when the content of Ce was 0.1wt%.
