Guangxi University XingJian College of Science and Liberal Arts, Nanning 530005, China ) Abstract: With the improvement of peoples environmental awareness, lead-free solder alternative to conventional tin lead solders has become an inevitable trend in electronic industry. Because of the melting point close to the traditional tin lead solder and excellent mechanical properties, Sn-Zn lead-free solders has been widely concerned and is expected to replace the traditional solder. The Sn-Zn lead-free solder has some problems in the wettability, oxidation resistance, corrosion resistance etc, moreover, the corrosion resistance of solder for electronics life and safety plays a decisive role. Therefore, having a good corrosion resistance is one of the key ways of lead-free solders’ development. Study on the corrosion resistance of Sn-Zn lead-free solders which have been researched most, then points the effect of alloying elements on Sn-Zn so
