Description

technical field [0001] The present application relates to the technical field of electrical connector detection, in particular, to an electrical connector reliability evaluation system based on intermittent fault generalized strength and an electrical connector reliability evaluation method based on intermittent fault generalized strength. Background technique [0002] The most distinctive feature of intermittent faults is that the time of occurrence is uncertain and the duration is random. Its essence is the potential defect of the product or a certain damage and degradation state under the long-term action of environmental stress such as vibration and temperature and working load. Among them, the pins of the connecting parts are loose or fatigued Temporary circuit disconnection intermittent faults caused by thermal sensitive components, wire breakage or wear, noise components, solder joint cracks, etc. are wear-out intermittent faults, which account for a large proportion i...
