摘要
综合了国内外含稀土元素Pr,Nd的无铅钎料最新研究成果,归纳并总结了添加稀土元素Pr,Nd对无铅钎料(Sn-Ag-Cu,Sn-Cu(-Ni)以及Sn-Zn钎料等)的组织和性能的影响规律,分析了稀土元素Pr和Nd对无铅钎料焊点可靠性的影响以及稀土相表面Sn须的形貌与生长机制,并展望了稀土元素改性无铅钎料研究的发展趋势,为进一步开发性能更优良的新型无铅钎料提供了参考依据。
The research status on the development of lead-free solders bearing Pr and Nd were reviewed and the effects of Pr and Nd on the microstructure and properties of Sn-Ag-Cu,Sn-Cu(-Ni) and Sn-Zn solders were summarized systematically. Moreover,the reliability and tin whisker problems by adding Pr and Nd also were analyzed. Synchronously,the developing trends of rare earth elements modified solders were prospected,which provides a base support for the developing of new lead-free solders.
