Abstract

PURPOSE:To automatically check a printed board for continuity and to reduce the number of checking processes, by a method wherein two checking probes on a printed board are brought into contact with the checking point of the printed board, and the continuity between the two probes is checked. CONSTITUTION:Various type of printed board circuits and data of a check point are recorded in a magnetic recorder 10 beforehand. A printed board 13 to be checked for continuity is set in a given position, and the data of the check point are read from the magnetic recorder 10 through the instruction of the type and drawing number of the printed board 13 to a controller 9. In consideration of a positional relation of arms of X, Y stages 1, 2 respectively, and the sequence of the check points based on the data, the X-stage 1 and the Y-stage 2 are driven according to a given program to bring probes 5 and 6 into contact with their respective check points. A continuity condition between the two probes 5 and 6 is detected by the controller 9 to be indicated in an indicator 11 to be further recorded on a recording paper by a printer 12.
