Abstract

PROBLEM TO BE SOLVED: To eliminate the need for a large-scale checking apparatus, by extracting terminal signal of an IC clip and a bus signal of a test substrate via cables, and inspecting presence or absence of a short circuit between pins in a PCI bus board. SOLUTION: In an inspected circuit board 1, a signal of a PCI bus is connected from a PCI bus control LSI 2 to a PCI bus connector 4 via a direct pattern. An IC clip 3 takes out a terminal signal from a pin of the LSI 2. A test substrate 5 fetches a bus signal from the connector 4. Then the respective parttern signals are extracted via cables 6, 7, and sent to a short circuit checking unit 8. The unit 8 which inputs the pattern signals checks a short circuit between the pins. Thus, since the connector 4 mounted on the board 1 is connected to the pattern, a large scale checking apparatus is eliminated.
