一种用于铜铝焊接的锡锌多元合金焊料及制造方法
摘要：
一种用于铜铝焊接的锡锌多元合金焊料及制造方法，涉及一种锡锌多元共晶无铅焊料及制造方法。它由下述重量百分比的原料组成：锌Zn3%～7%；镍Ni0.1%～0.5%；碲Te0.05%～0.2%；钕Nd0.01%～0.05%；锡基抗氧化合金1%～1.5%；锡Sn为余量。本发明从锡锌焊料的配方及制造方法上取得突破，最终解决了焊点开裂问题。生产出的合金焊料在进行铜铝焊接后可在双85环境中1000小时不发生开裂，保证了焊点在恶劣环境中的稳定性和持久性。
摘要（英）：

Tin zinc multi-element alloy solder for soldering copper and aluminum and a preparation method thereof relate to tin zinc multi-element eutectic lead-free solder and the preparation method. The tin zinc multi-element alloy solder comprises, by weight, 3%-7% of Zn, 0.1%-0.5% of Ni, 0.05%-0.2% of Te, 0.01%-0.05% of Nd, 1%-1.5% of tin-based oxidization resistant alloy and the balance Sn. A formula of the tin zinc solder and the preparation method make a breakthrough, and a soldered spot cracking problem is solved finally. The produced alloy solder can not crack within 1000 hours under the double-85environment after conducting copper-aluminum soldering, and the stability and the durability of the soldered spot in a severe environment are guaranteed.
