Abstract

PURPOSE: To make continuity test possible without damaging the conductor pattern of a print board by interposing a protection film, which can be conductive only to a prescribed through hole part, between a checker pin and the print board.
CONSTITUTION: Insilation protection film 10 having hole 12 corresponding to land part 3 of through hole 5 of print board 1 is propared, and the size of hole 12 is slightly larger than land part 3 of print board 1, and a part, at least, of each land part 3 is exposed from hole 12 when protection film 10 is superposed onto the print board. By superposing protection film 10 onto the print board, a struck trace, etc., can be prevented from being left at point S of pattern 6 of print board 1 when the checker pin descends to the part corresponding to point S because protection film 10 exists in this part, so that the pattern can be prevented from being damaged.
