摘　　要：电子元器件在应用过程中经常出现污染腐蚀失效。因此,查找引起失效的污染和腐蚀源是分析技术的关键。通过几种不同类别电子产品失效分析案例,研究了离子色谱检测在板面残留、工艺辅料、产品包封料、环境异物中污染腐蚀源的检验和分析方法,并与传统的形貌观察、绝缘阻抗测试、EDS成分分析、红外光谱分析的结果进行综合对比和验证。明确了离子色谱检验方法在电子元器件腐蚀失效分析中的应用场景、取样方法和结果分析方法,为离子色谱在电子元器件腐蚀失效预防中的工程应用提供指导和借鉴。Pollution corrosion failure often occurs in the application of electronic components. The key of analysis technology is to find out the pollution and corrosion source causing failure. Through several failure analysis cases of different types of electronic products, the inspection and analysis methods of ion chromatography(IC)detection of pollution corrosion sources in the board residue, process auxiliary materials, product packaging materials and environmental foreign matters were studied, and the results were comprehensively compared and verified with the results of traditional morphology observation, insulation impedance test, EDS component analysis and infrared spectrum analysis. The application scenarios, sampling methods and result analysis methods of ion chromatography in the analysis of corrosion failure of electronic components were clarified. The reference significance of application of corrosion failure prevention engineering of electronic components in enterprises was summarized and revealed.
