CIRCUIT PATTERN INSPECTION DEVICE,CIRCUIT PATTERN INSPECTION METHOD,AND RECORDING MEDIUM

摘要

A circuit inspection device capable of reliably and easily detecting defects of a circuit board. An inspection signal is supplied to one of conductive patterns (20) from a power supply unit (30) capacitance−coupled with conductive patterns (20) disposed in rows. This inspection signal is detected by an open sensor (40) capacitance−coupled with all the other ends of the conductive patterns (20) in rows, and a pattern disconnection is determined to be cut off when the output is considerably reduced. The inspection signal is also detected by a short sensor (50) offset to the power supply unit (30) capacitance−coupled with the patterns of two rows of the conductive patterns (20) in rows, and if the detected signal is considerably increased or decreased, a pattern is determined to be short−circuited and acceptance or rejection of the patterns is inspected.
