Abstract: An accelerated degradation mechanism consistency discriminant test system with data acquisition,derivation and manage functions was developed.For a certain type of resistor,firstly,the test cost is used as a limiting condition to improve the accuracy of accelerated degradation model parameter estimation.The sample amount and test time of the accelerated degradation mechanism consistency discriminant test are optimized,and then the test plan is given.According to the parameters of the required test,the software and hardware parts of the test measurement system are designed and developed.The system has the characteristics of high test accuracy,high degree of automation,large number of measurable samples,and many kinds of measurable devices,so that it provides a data foundation for failure mechanism consistency analysis and reliability assessment.

Key words: accelerated degradation mechanism consistency discriminant test, test optimization, test system, failure mechanism consistency analysis
