Abstract

A lead-free solder alloy, which is characterized in comprising 1~4 wt% of Ag comprising at least one of Bi, In so that the A value in formula (1) is higher than 5.00 and the B value in formula (2) is lower than 6.90, and the remaining part of Sn. A = [Ag wt%]+1.23[Bi wt%]+0.52[In wt%] ...(1) B = [Ag wt%]+1.19[Bi wt%]+0.50[In wt%] ...(2)
