| 摘 要： | 采用真空熔炼技术成功制备Sn-(8.98-x)Zn-0.02Al-xLa(x=0.02～0.12)焊料。采用XRD衍射、DTA、SEM等手段分析了焊料的熔点、显微结构及焊料对Cu基板的润湿性等性能。结果表明,添加适量的稀土元素La能较好地提高Sn-Zn-Al基焊料熔点,改善焊料的铺展能力和组织均匀性。在Sn-(8.98-x)Zn-0.02Al-xLa焊料中,稀土La的最佳添加量为0.04%。

| Abstract: | The Sn-(8.98-x)Zn-0.02Al-xLa(x=0.02～0.12) solders were prepared by vacuum melting technique.Melting point,microstructure of the solder and its wettability on Cu substrate were analyzed through X-ray diffraction(XRD),DTA(differential thermal analysis),SEM(scanning electron microscope).The results show that proper rare earth La can effectively increase the melting point of Sn-Zn-Al solder,and improve the spreading ability as well as homogeneity of microstructure.With 0.04%La addition,Sn-(9-x)Zn-0.02Al-xLa solders exhibit the desirable comprehensive properties. |
