稀土元素Ce对锡银铜无铅钎料润湿性及钎缝力学性能的影响

Effect of cerium on wettability and mechanical properties of soldered joints for Sn-Ag-Cu lead free solder

    摘要
  • 摘要: 采用STA-5100型可焊性测试仪和STR-1000微焊点强度测试仪,对添加了稀土元素Ce的Sn-3.8Ag-0.7Cu无铅钎料的润湿性及钎缝的力学性能进行了研究。试验结果表明,Ce的加入,可以改善钎料的润湿性,质量百分含量为0.03%~0.05%时效果最好,温度升高以及通入氮气均可以明显地提高Sn-3.8Ag-0.7Cu-Ce无铅钎料的润湿性;当Sn-3.8Ag-0.7Cu钎料中稀土元素Ce的质量百分含量为0.03%时,钎缝的力学性能最佳。

     

    Abstract: Based on Sn-3.8Ag-0.7Cu lead free solder,the effect of cerium on the wettability and mechanical properties of soldered joints were investigated by means of Solder Checker STA-5100 and STR Joint Strength Tester.The results showed that the wettability of solder can be improved by adding small amount of Cerium and the optimum was in the range of 0.03wt.% to 0.05% wt.With the rising of testing temperature,the wettability is greatly improved gas well as by adding nitrogen.Adding small amount of Cerium to Sn-3.8Ag-0.7Cu lead free solder,the mechanical properties of soldered joints is enhenced and the optimum is about 0.03% wt.
