ABSTRACT:
A method for testing an optical disc drive control PCB using a test jig featuring a reference optical pick-up head. The method includes steps for measuring an output of the reference optical pick-up head (OPU) laser, comparison of the OPU output to the output of an optical disc drive control PCB under test and, for comparing the measured value to a predetermined range of values and accordingly determining whether the optical disc drive control PCB under test is acceptable.
