In this paper, the latest representative research results regarding Pb-free solder for the high temperature application were reviewed. Regardless of many excellent properties, Sn-Sb alloy system is still very restrictive in the possibility for the high temperature application because of its low melting point. Bi composite solder including CuAlMn particles was also judged to be incongruent for the commercial application because of its many physical problems. However, Bi-10Ag alloy showed the possibility of a commercial high temperature solder in the application condition of Cu substrate, and Bi-Cu-Sb alloy was estimated as a high temperature solder composition having superior properties when it was considered with various viewpoints.
