摘要
The fatigue rupture taking place at a soldered joint dueto a heat cycle can be alleviated. Effective use of Cu addedsolder. This solder is basically consisting of 57 to 65% ofSn, 0.1 to 0.5% of Sb, 0.002 to 0.5% of Te and balancing Pb,all in weight. This invention has introduced a solder alloycomprising the base composition with supplement of 0.001 to0.5% of Ga and/or 0.1 to 0.3 of Cu, all in weight.
