In order to overcome the difficult problem of circuit board fault diagnosis,this paper proposed a method of circuit board fault based on the BP neural network. This method used membership function to fuzz the vector of fault space and maps the vector through BP neural network. Experimental results show that the BP neural network is accurate as well as precise and it can be used to diagnose complicated circuit board.
