摘要
本文介绍了一种针对工业控制系统,军工产品在加速应力测试和失效分析验证时采用的工装系统和方法。普通的高温极限测试仅是测试到主板高温不开机为止,由于无法区分故障件,从而针对主板的进一步极限温度测试就无法开展。通过本系统介绍的独立温控工装就可以对故障件进行温度控制,继续进行下一步的高温极限测试,从而逐渐确认主板关键件的高温破坏极限和工作限制;另外,在实际的低温故障分析时,也可以利用此工装实现局部器件的低温敏感测试,为低温不开机问题提供解决工具。
This paper introduces a tooling system and method for industrial control system and military products in accelerated stress test and failure analysis. The ordinary high temperature limit test only tests to the motherboard, the high temperature does not switch on, because cannot distinguish the breakdown piece, thus it is unable to carry out the further limit temperature test for the motherboard. Through the independent temperature control system of the equipment can control the temperature of the fault piece, to test the high temperature limit of the next step, thus gradually confirm the key parts of the motherboard failure limit and high temperature limit;in addition, in the actual fault analysis of low temperature, it can do low temperature sensitivity test to realize the local device, as a solution for low temperature not booting problems.
