Abstract: PURPOSE:To inspect an open short circuit at the same time by connecting resistances to an input/output pin and a power pin and short-circuiting both resistances, and then measuring and comparing the value of the resistance between a reference power source pad and a pad to be inspected with a criterion value. CONSTITUTION:An input/output pin short jig 2 with resistance is provided with the resistance for the signal pin which has a resistance value R1 corresponding to a signal input/output pad 7 and the resistance 4 for the power source pin which has a resistance value R2 (R2<R1) corresponding to power source pads 9 (VEE), 10 (VRF), and 11 (GND). One terminal sides of the resistances 3 and 4 are connected together to the input/output pin 12 by fitting a circuit board 1 to be inspected to the jig 2. Other terminals are all short-circuited in the jig 2. Then a prober 5 is used to probe a reference power source pad 11 and a prober 6 is made to probe the pad to be inspected, thereby measuring the resistance value between the both. The obtained measured value is compared with the criterion to decide an open error when the measured value is larger or a short-circuit error when not.
