Abstract

Automotive relays are the important control components in vehicle electrical system. Temperature is one of important factors in reliable operation of automotive relays. Based on the analysis on failure modes of automotive relays at high and low temperature and under temperature cycling condition, this paper introduces reliability indexes and proposes one test plan of the reliability compliance test for automotive relays under temperature cycling condition. The reliability test was carried out and the failure analysis on the typical failure samples was presented.
