Abstract
PURPOSE:To shorten the time of inspecting the pattern conduction with a simple and quick supply of an inspection signal only to a valid pin by memorizing the position information of the valid pin separated from a valid contact pin by way of a mask and a conductive plate. CONSTITUTION:As soon as a mask 2 making up an insulator basic pattern sheet is pressed against a contact pin 4, valid pins 4a... are separated from invalid pins 4b.... Based on the separation of the pins 4a... through a conductor 10 making up a calibrating substrate, the position information of the pins 4a... is memorized in a memory section of a CPU7. After such a quick separation of the valid pins, an inspection signal from the CPU7 is applied only to a point based on the position information memorized of a substrate 1 to be tested and the result is checked up with a correct connection state from a reference connection file 8 read out through the CPU7. Such a simple and quick supply of the inspection signal only to the valid pins enables inspection of the pattern conduction on a printed circuit board in a short space of time.
