Make a uniformly orthogonal testing for 20 kHz signal PCB of radar

and use the testing data to analysis the testing results.Conclude the general rule of performance degradation of electronic equipment in the environment of temperature and humidity;Aiming at the electronic equipment reliability prediction problem

which play an important role in fault prediction

present an new method about electronic equipment reliability prediction based on Combine Environmental ALT.This method extends the performance degradation theory to accelerated performance degradation theory.The no failure data problem in ALT was resolved combining the theory and traditional reliability prediction.In the end

validity of this method was proved by an example.
