A common printed circuit board reliability index Analytical Method

Common printed circuit board of the present invention disclosed in the reliability index rapid analysis method, comprising the steps of: establishing the reliability of the electronic component characteristic parameter distribution model; obtained by calling the interface functions of electronic components to a printed circuit board list; compilation of a printed circuit board detailed list of electronic components; electronic components according to the reliability of the printed circuit board detailed list of parameters characteristic distribution model and the electronic component, to obtain a list of generic failure rate parameter table contains all the electronic components; calculating a printed circuit board obtained in the use environment under failure rate; failure rate in accordance with the printed circuit board in a use environment, the system calculates the reliability of the circuit board, no system reliability, system MTBF life. The present invention has instructions to the design of the circuit board, to achieve continuity between the circuit board design and reliability analysis, user-implemented crossing a circuit board design and reliability analysis, thereby improving the efficiency of the circuit board design.
