电子产品在温度循环试验中未采取防凝露积水措施或方法不当,使试验箱体内的水分堆积在某机载站控制系统微电机驱动板上,导致驱动板上的模块A出现漏电和短路,试件性能异常,系统故障发生.通过对该控制分系统温度循环试验中失效模块A的分析,得出失效原因为试验中防凝露积水方法不当,可有针对性地对温度循环试验中防凝露积水进行改善.
電子產品在溫度循環試驗中未採取防凝露積水措施或方法不噹,使試驗箱體內的水分堆積在某機載站控製繫統微電機驅動闆上,導緻驅動闆上的模塊A齣現漏電和短路,試件性能異常,繫統故障髮生.通過對該控製分繫統溫度循環試驗中失效模塊A的分析,得齣失效原因為試驗中防凝露積水方法不噹,可有針對性地對溫度循環試驗中防凝露積水進行改善.

@@@@If anti-waterlogging measures of ordnance electronic products are not taken in temperature cycle test, or if it is taken improperly, water vapor of test box will condense on the components of the subsystem. Thus, the components will have a leakage of electricity and abnormal performance, which will make the whole system failure. The failure components in the subsystem temperature shock test were analyzed. The causes of failure anti-condensation measures were put forward. A solution to the protection measures of anti-condensation in the temperature shock test was provided.
