摘要
随着无铅钎料性能的提升和人们环保意识的提高,无铅钎料也逐渐被应用在特殊环境中。介绍特殊环境用无铅钎料可靠性的研究进展及趋势,分析特殊环境中无铅钎料焊点失效的原因,探讨各种特殊环境中提高无铅钎料可靠性的方法和机理,如微合金化、颗粒强化和基板改善,总结目前无铅钎料可靠性研究存在的不足,对无铅钎料未来的研究方向提出建议。
Lead-free solders are applied under special conditions with the improvement of property of the solders and people's awareness of environmental protection.The research status and development trend of lead-free solders used under special conditions were reviewed synthetically.First of all,the failure mechanism of solder joints under different special conditions was discussed.Moreover,the ways to enhance the reliability of lead-free solders under several special conditions were reported and analyzed,such as microalloying,particle strength and substrate improvement.In addition,the defects of the current reliability research of lead-free solders were summarized,and the further research was prospected.
