摘　　要：从连接器电装清洗干燥后隔离电压异常问题入手,对异常批次的电路板加长烘干干燥时间再进行隔离电压的测试数据统计分析,初步确定发生隔离电压异常的原因为连接器烘干时间不够导致绝缘特性变化。进一步试验验证并参阅相关资料,最终确认含有连接器的电路板电装清洗干燥后烘干干燥的时间。并对改善后的效果进行了跟踪验证。Starting with the problem of abnormal isolation voltage after cleaning and drying of connector electrical equipment,the drying time of circuit boards in abnormal batches is extended,and then the test data of isolation voltage are statistically analyzed.It is preliminarily determined that the cause of abnormal isolation voltage is the change of insulation characteristics caused by insufficient drying time of connector.Further test and verify and refer to relevant data to finally confirm the drying time after cleaning and drying the circuit board electrical assembly containing connectors.The improved effect is tracked and verified.
