摘要
先进的表面表征技术在无铅焊料的研究中发挥着至关重要的作用.作为一种具有高分辨率、高灵敏度的表面分析方法,X射线光电子能谱(X-ray photoelectron spectroscopy,XPS)可以对元素种类及化学价态等信息进行精准分析.文章主要介绍了 XPS在无铅焊料的组分及其氧化、润湿、腐蚀、电迁移等性能方面的应用,并多角度阐述了无铅焊料及焊点性能的影响机理,致力于为日后XPS在无铅焊料中的研究工作提供一些帮助.
Abstract
Advanced surface characterization techniques play a crucial role in the investigation of lead-free solders.As a surface analysis method with high resolution and sensitivity,X-ray photoelectron spectrosco-py(XPS)can accurately analyze the element type and valence states.In this paper,the application of XPS in analysis of chemical composition,oxidation,wetting,corrosion,electromigration and other properties of lead-free solders was mainly introduced.The influencing mechanisms of lead-free solders and solder joint properties were comprehensively discussed from multiple perspectives,which could provide some ref-erences for the studies of lead-free solders by XPS in future.
