ABSTRACT

Computer-assisted repair (CAR) refers to that automated process which implements the rework of defective or modified product such as printed wiring boards (PWBs) and electronics assemblies. Diagnosis is accomplished by appropriate human and/or software resources. Relevant parts performance and specifications are called up from a previously established data base. Real-time communication of repair data and storage of test results. CAR systems should collect fault data in real time from a number of testers and use the data to locate the fault within the product. PWB testers can transmit information to the CAR system via a local area network or a simple RS 232 data link. In electronics manufacturing, failures either of the components or of the assembly process must be dealt with. CAR was conceived out of this need to repair previously assembled product. Indeed, with higher circuit densities on PWB assemblies, it becomes difficult even to contact the surface with precision in order to test with a probe.
