摘要
采用SEM&EDS及FT-IR等方法,对短路的IC元件进行失效分析。结果表明IC元件引脚上的焊料遭受残留助焊剂腐蚀,腐蚀产物连续聚集于引脚间从而导致了IC元件的短路。
Short-circuit of IC component was analyzed by means of SEM&EDS and FT-IR. The results showed that the solder on pins of IC was corroded by flux residue, intervals between IC pins was fully filled with corrosion products which lead to short-circuit of IC component.
