Automatic wiring check and fault location of disconnected wires for bare printed circuit boards without parts and backplane wiring become important for increasing reliability of digital equipments. In this paper, a selection of the input terminal to minimize the number of wires masked by a certain disconnected wire is presented first for efficient test procedures and it is shown that an input terminal should be selected as the center of wiring moment. A step_by_step checking method and an AND/OR gate checking method are presented secondly for automatic wiring checking to locate multiple discontinuity failures on wires, and several testing algorithms are shown. In the step-by-step checking method, it becomes clear that the failure modes are closely related to the test procedures, and the high effectiveness of the AND/OR gate checking method for fault location is proved by computer simulation.
