PURPOSE:To inspect quickly and simply the disconnection and short-circuit of a pattern of a printed circuit board with good accuracy, by putting rubber sheets conductible electrically under pressure between the printed circuit board and a jig board for inspection opposing regularly to said printed circuit board. CONSTITUTION:Jig circuit boards 33 for inspection are provided with an inspection end 2 corresponding to a pad of the inspection end of a printed circuit board 1, an outward drawing-out pattern 5 and a connector pad 4, etc. The disconnection and short-circuit of the face and back pattern of the printed circuit board are inspected quickly and simply with good accuracy by opposing regularly these circuit boards 3, 3 to the printed circuit board 1 and conducting electrically the pad 4 after putting rubber sheets 6, 6 conductible electrically under pressure between the circuit boards 3, 3 and the printed circuit board 1. |
