摘要

在无铅焊料中通过添加微量的Te来改善其焊接性能

Te在空气中易氧化

不易在无铅焊料中直接添加

介绍了ECAP技术制取Sn-Te中间合金的措施与过程。带盲孔挤压坯锭中灌入按一定比例混合均匀的Sn粉和Te粉

再通过ECAP技术低温反复挤压

Te粉合理分布于Sn基体中形成Sn-Te中间合金。

Abstract

Welding performance of lead-free solders was improved by adding Te.However

Te is not easily added directly in the lead-free solder as a result of easily oxidized in air.Sn-Te master alloy was prepared by ECAP.Tellurium powder and tin powder homogeneously mixed with a given proportion was poured into a uniform extrusion billets with blind hole

and then repeated extrusion by ECAP extrusion technology at low temperature

so tellurium powder can uniformly distribute in the matrix to form SnTe master alloy.
