摘要
系统研究了添加微量稀土Er对Sn3.8Ag0.7Cu钎料合金显微组织和性能的影响,通过对钎料的熔化温度、润湿性能、接头剪切强度的测试及显微组织观察,指出含微量稀土的SnAgCuEr合金是性能优良的无铅钎料合金,同时确定了最佳的Er含量范围.
The effect of minimal amount of rare earth Er on the microstructure and performance of Sn3.8Ag0.7Cu solder alloy, has been systematically investigated. Through measuring the melting temperature, wettability and joint shear strength, and observing the microstructure, it is indicated that the SnAgCuEr alloy containing rare earth is a lead - free solder with an excellent performance. At the same time the best content of Er is de- termined.
