STRUCTURE AND METHOD FOR JOINING METAL MEMBERS

摘要

Sn-Zn alloy is plated on at least one of a first metallic member and a second metallic member, Sn-Ag alloy is used as a solder, the first metallic member and the second metallic member are connected by the solder, and a connection structure of metallic members is therefore produced. Heat degradation of plating and the contact corrosion between solder and plating can thereby be prevented, solderability can be improved, and qualities such as corrosion resistance and connecting strength at the connection structure can be improved.
