摘要
分析了目前国内在组件温度筛选方面的一般做法,吸收国外加速试验的经验,并借鉴定量筛选中根据成效率确定无故障检验时间的方法,提出了组件温度筛选中各参数(如温度范围、温度变化速率、高低温保持时间和循环数)的确定方法,并以一种税控加油机主板的温度筛选为例,介绍了组件温度筛选方法研究中所总结的一些经验。
Analyzing the general method of temperature screening for assembly in our country, combined with the experience of accelerated testing abroad, we proposed a definition method of parameters, such as temperature range, rate of change of temperature and dwell time. In this paper, we introduce some experience in a temperature screening of a mainboard.
