DC-DC电源模块电特性参数测试误差影响因素的分析

Analysis of Influencing Factors of DC-DC Power Supply Module Test Error

该文分析了DC-DC电源模块电特性参数失效故障的影响因素,并结合故障树分析法,定位出故障是由于测试夹具接触问题所引起的。通过三款接触方式不同的测试夹具进行对比论证,进一步分析夹具的接触方式对电源模块测试的影响,并提出一种新型的测试夹具设计方案,能够有效缩减时间和硬件成本,大幅提升测试效率。

In this paper,the influencing factors of electrical characteristics failure DC-DC power supply module are analyzed,and the fault tree analysis method is combined to locate the fault caused by the contact problem of test failure.Through the comparative demonstration of three test fixtures with different contact modes,the influence of fixture contact modes on power supply module testing is further analyzed,and a new design scheme of test fixture is proposed,which can effectively reduce the time and hardware cost and greatly improve the test efficiency.
