| Abstract: | The authors briefly introduce the accelerated life model of electronic and electrical parts with environment stress and the calculating method for reliability test. Firstly, three acceleration models and their applications are introduced; secondly, the reliability test requirements are calculated according to the given reliability and confidence level. Last, according to the test results, the actual product reliability is obtained to guide the design. |
