Abstract
PURPOSE:To know a shortcircuit position without cutting pattern wiring, by allowing a pulsating current to flow between shortcircuited wiring patterns and detecting the change in a magnetic field generated by said current. CONSTITUTION:The shortcircuit of the wiring patterns of a printed circuit board 2 is preliminarily inspected by an inspecting device and the output of a pulsating current generator 1 is connected to the connector pins 3, 4 between the shortcircuited wiring patterns of the printed circuit board 2. A detection coil 10 for detecting the magnetic field generating from a pulsating current is provided and the output thereof is connected to a speaker 12 through an amplifier 11. The detection coil 10 is allowed to approach measuring points 8, 9 or 13, 14, 15 to detect the pulsating current and it is detected that the pulsating current flows through the measuring points 8, 9. From this, a place having a projection pattern 7 is detected easily without cutting the wiring patterns.
