摘要:
为解决传统加速寿命试验存在的试验时间过长、样本量大的缺点,需要设计对比加速寿命试验。首先通过分析通孔焊点失效的故障原理,明确失效敏感应力;然后基于前期统计信息和失效敏感应力,设计对比加速寿命试验方案;最后针对基准插件通孔焊点实施对比加速寿命试验,并验证了待评估插件通孔焊点的寿命水平。结果表明,相对于传统的加速寿命试验,对比加速寿命试验所需试验时间短、样本量较少,并参考基准插件通孔焊点的寿命基准,验证了待评估插件通孔焊点的寿命不足 10 年,需要进行工艺改进。
Abstract:
In order to solve the shortcomings of traditional accelerated life test, such as long test time and large sample size, it is necessary to design comparative accelerated life test. Firstly, through the analysis of the failure mechanism of through-hole solder joints, the failure sensitive stress was defined; Secondly, based on the previous statistical information and the failure sensitive stress, the comparative accelerated life test scheme was designed; Finally, the comparative accelerated life test was carried out for the reference plug-in through-hole solder joints, and the life level of the through-hole solder joints to be evaluated was verified. The results showed that compared with the traditional accelerated life test, the comparative accelerated life test required shortened test time and fewer samples. Referring to the life benchmark of reference plug-in through-hole solder joints, it was verified that the life of the evaluated plug-in through-hole solder joints was less than 10 years, and the process improvement was needed.
