METHOD OF TESTING NON-COMPONENTED LARGE PRINTED CIRCUIT BOARDS WITH A FINGER TESTER

摘要

The present invention , having a conductive path , scan the printed circuit board of large area that is not loaded relates to a method of . According to the method according to the present invention , the circuit board is divided into a number of test segments (segment) , but the single passage of the conductor extending beyond the segment being examined by capacitive measurement of the end point of the segment , one of the conductive path single measurement of a plurality of measured values belong to the capacity to markedly different with different measurements , it is determined that the conductive path is opened .
