综合环境应力可靠性试验，对于验证产品可靠性平均无故障工作时间（ＭＴＢＦ）和暴露产品设计、元件选用、生产工艺等方面的缺陷有着十分重要的作用。综合环境应力可靠性试验设备是实施该项试验的重要手段。本文详述 Ｈ３８８０－Ｖ８９０Ｂ试验系统的布局、功能、参数及主要技术，旨在向试验同行介绍目前试验设备的最新技术动态。同时希望资源共享，为暂不具备大型综合环境应力设备的单位提供协作，共同为提高我国的装备技术水平作出贡献。
The comprehensive environmental stress reliability test plays an important role in verifying the MTBF of product reliability and the defects in product design, component selection and production process. Integrated environmental stress reliability test equipment is an important means of implementing the test. This article details the layout, functions, parameters and main technologies of the H3880-V890B test system. It aims to introduce the latest technical developments of the current test equipment to the test counterparts. At the same time, we hope that resources will be shared and cooperation will be provided to those who temporarily do not possess large-scale comprehensive environmental stress equipment to jointly contribute to raising the level of equipment and technology in our country.
