Abstract :
PCB fault detection and positioning is always a complex and difficult work. This thesis designed a fault diagnosis system for PCB circuit, which uses voltage signals as incentive signals and the voltage or current response signals as the output. Fault tree is established and fault searching and positioning method introduced fault dictionary analysis according to the fault tree. Through simulation analysis, it is indicated that fault diagnosis of circuit board based fault tree analysis is feasible.
