Abstract

PURPOSE:To easily test a high-density package by grounding an ECL (emitter coupled logic) LSI and the power line of a terminal resistance respectively, and bringing a prober into contact with the input terminal of the terminal resistance and finding a current value corresponding to each output value. CONSTITUTION:The changeover switch 15 of the prober 16 is operated to the side of a power source ES1 and the prober 60 is brought into contact with the input terminal A of a terminal circuit 40. The current voltage turns off both transistors (TR) 11 and 3 and resistance values calculated by a voltmeter 13 and an ammeter 14 are equal to the resistance of the circuit 40. Then the switch is changed over to the side of a power source ES2, and TR 3 turns off and the TR 11 turns on, so that the current flows to the ground through terminals A and B and the TR 11 simultaneously with a resistance 12. For the purpose, the resistance values calculated by the voltmeter 13 and ammeter 14 are compared with a prescribed value to easily inspect whether or not a printed wiring pattern is normal and whether or not the LSI can be mounted.
