". The failure curve of electronic components varies with time. Through "Test re-screening" can only eliminate the early failure of the product, and can not reduce the failure rate during accidental failures. Therefore, screening can only improve the reliability of product use, and can not really improve the product's "intrinsic quality and reliability." Reliability is designed and manufactured.
