Environmental Stress Screening for electronic equipment by random vibration: a critical approach to reliability estimation and planning

摘要

Individuated a deficiency of manufacturing practice and standards in Environmental Stress Screening, ESS, we proposed a process of screening with random vibrations in which the time of test is optimized according to the components and the layout board, trying also to minimize the cost of the same test. The screening test is implemented and the results are discussed in this paper.
