几种环境应力试验的失效模式探讨

Discussion on Several Failure Modes of Environmental Stress Testing

环境应力试验是检验产品质量的重要手段之一,对评价产品质量意义重大。产品使用环境复杂多样,环境温度是影响产品性能不可避免的关键因素。建议采用高温应力、温度循环应力、温度冲击应力三种环境应力进行筛选试验,试验中向产品施加合理的环境应力和电应力。本文对环境应力筛选试验的失效模式进行了讨论。

Environmental stress testing is one of the important means for testing product quality, which is very significant for product quality evaluation. Products will be used in various environments, so the environment temperature is an inevitable influence on most products. We suggest that high temperature stress, temperature cyclic stress, and temperature shock stress be used for environmental stress screening tests, with proper environment stress and electrical stress applying to the product. This paper discuses the failure modes of environmental stress screening tests.
