Abstract: The schematic diagram of CD-ROM driver's PCB (Printed Circuit Board) is analyzed from the angle of fault diagnosis, and the diagnostic information flow model of CD-ROM driver's PCB is built. The observing relations among tests and relations between the faults and tests are emphasized and described clearly in this model. Based on this model, fault diagnosis of CD-ROM driver's PCB is studied, and efficiency of the model is verified.
