| titleOfInvention | Solder paste and flux for solder paste |
| abstract | PROBLEM TO BE SOLVED: To provide a solder paste which is less likely to change with time, has excellent wettability, has high mechanical properties, has good wettability and spreadability of solder, and suppresses the occurrence of dewetting. SOLUTION: A solder paste containing a specific solder powder and flux is adopted. Solder powder is at least one of As: 25 to 300 mass ppm, Pb: 0 mass ppm and 5100 mass ppm or less, and Sb: 0 mass ppm and 3000 mass ppm or less, and Bi: 0 mass ppm and 10,000 mass ppm or less. In addition, it contains a solder alloy having an alloy composition consisting of the balance Sn and satisfying the equations (1) and (2). The flux comprises an organic acid selected from dimer acid, hydrogenated dimer acid, trimer acid and hydrogenated trimer acid. 275 ≦ 2As + Sb + Bi + Pb (1) 0.01 ≦ (2As + Sb) / (Bi + Pb) ≦ 10.00 (2) [Selection diagram] None |
