摘要
在钎料中引入适当的纳米颗粒,可以改善熔融钎料对母材表面的润湿性,细化钎料接头组织,抑制界面金属间化合物的生长,有效提高微型焊点的可靠性。介绍了纳米增强颗粒复合钎料的研究热点及制备方法,分析了纳米颗粒对钎料的熔点、润湿性、力学性能及界面IMC的影响,展望了纳米颗粒复合钎料在电子微连接技术中的应用前景。
The wettability can be improved and the organization of solder joints can be refined after adding proper nano-partieles in the molten solder. Meanwhile, the development of intermetallic com- pound （IMC） can be restrained and the reliability of welding spot can be enhanced. Hot-topics of nano-eomposite solders and preparation methods were introduced. The effect of nano-partieles on the melting point and the wettability, the mechanical property and the IMC were analyzed. The applica- tion prospect of nano-composite solders was discussed.
