合金元素对Pb-Sn-Sb-Bi-P-Cd系软钎料性能的影响

Effect of alloy elements on the properties of the Pb-Sn-Sb-Bi-P-Cd solders

研究了Sn、Sb、Bi、P、Cd五种合金元素对Pb Sn Sb Bi P Cd系软钎料的熔化温度、润湿性能、抗剪强度等性能的影响.结果表明,加入适量的Sn、Bi、Sb、Cd可以降低液相线温度;加入适量的Sn、Cd可改善润湿性能;加入适量的Sb、Sn、P可提高抗剪强度.

The effect of Sn,Sb, P, Bi and Cd on the properties of Pb-Sn-Sb-Bi-P-Cd solders is studied. The results of the experiment show that the melting temperature will be improved better when the proper Sn, Bi, Sb, Cd was added to the solders; the wettability will be improved better when the proper Sn, Cd was added to the solders, and the shear strength will be improved better when the proper Sb, Sn, P was added to the solders.
