Abstract

PURPOSE:To facilitate a deficiency detecting simulation of an IC tester, by arranging a circuitry which is allowed to simulate a leak by open, short-circuit and resistance components. CONSTITUTION:A socket adaptor 7 for a deficiency detecting simulation is connected in stead of a socket adaptor 8 used at a normal test. By switching an open switch 2 over to an open position, an IC to be measured and a measuring circuit within an IC tester are open to allow the simulation of an open deficiency of the IC to be measured. An adjacent pin short-circuit switch 3 turns ON the switch to cause a shift-circuiting of an adjacent pin thereby permitting the simulation of the short-circuiting of the adjacent pin of the IC to be measured. In addition, the open switch 2 is turned ON corresponding to a pin intended to simulate a leak by a resistance component. Then, a leak switch 4 is turned ON and subsequently, a resistance 80 desired to be simulated is selected with a resistance selection switch 50.
