Method for quickly analyzing universal reliability indicators of printed circuit board

The invention discloses a method for quickly analyzing universal reliability indicators of a printed circuit board. The method includes steps of setting up a reliability characteristic parameter distribution model of electronic components; acquiring an electronic component list by calling an interface function; compiling a detailed electronic component list of the printed circuit board; acquiring a table list containing universal failure parameters of all the electronic components according to the reliability characteristic parameter distribution model of the electronic components of the printed circuit board; calculating failure rate of the printed circuit board in the using environment; calculating system reliability, system unreliability and system average faultless service life of the printed circuit board according to the failure rate of the printed circuit board in the using environment. The design of the circuit board is of great guidance significance, continuity between the design of the circuit board and reliability analysis is realized, cross implementation of the design of the circuit board and the reliability analysis can be conveniently realized by users, and design efficiency of the circuit board is improved.
