摘要： The present invention provides a lead-free tin-silver-based soldering alloy which has a low melting point equal to alloy H without containing harmful lead, expensive In or the like, and has excellent mechanical characteristics, that is, a tensile strength, an elongation value and heat fatigue characteristic as compared with alloy H, and thus, is applicable to soldering work at a low temperature and can make products which have a high reliability and long useful life or durability. The lead-free tin-silver-based soldering alloy consists essentially of Ag: 2 to 4% by weight, Zn: 0.5 to 2% by weight, Bi: 2 to 6% by weight, and the balance being substantially Sn.
