| titleOfInvention | Solder alloys, solder powders and solder joints |
| abstract | An object of the present invention is to provide a solder alloy or the like which suppresses a temporal change of a solder paste, has a small temperature difference between a liquidus temperature and a solidus temperature and has high reliability. The solder alloy includes at least one of As: 10 mass ppm or more and less than 40 mass ppm, Bi: 0 to 10000 mass ppm, Pb: 0 to 5100 mass ppm, and Sb: 0 to 3000 mass ppm. The balance has an alloy composition of Sn and satisfies the formulas (1) and (2). 300 ≦ 3As + Sb + Bi + Pb (1), 0.1 ≦ {(3As + Sb) / (Bi + Pb)} × 100 ≦ 200 (2) [In the formulas (1) and (2), As, Sb, Bi, and Pb are alloys, respectively. It represents the content (mass ppm) in the composition. ] [Selection diagram] None |
