The printed circuit board(PCB)technology will continue to develop toward higher density and higher integration,so that PCB reliability problems will become increasingly prominent.This paper briefly introduces the failure mechanism of PCB.Combined with the existing standards and practical applications,three reliability test and evaluation methods of PCB are introduced in detail:failure rate prediction method,accelerated test prediction method and test identification method.We hope to provide some help for practitioners to carry out PCB reliability test and evaluation.
