Abstract

PURPOSE: To accurately determine the breakage condition of ICs by using a microcomputer.
CONSTITUTION: A measuring circuit 11 which supplies voltage and current to the IC10 to be measured and measures the magnitudes of the voltage and current thereof, a CPU21, a memory 22 into which programs are written, an RAM23 which stores the measurement data of the circuit 11 and a display means 32 are provided. The CPU21 increases the voltage exponential-functionally and stepwise to the IC10, measures the voltage and current at each step, stores the measured data in the RAM23. Comparing these with the similar measured value after adding stress to the IC10, decides whether they are within a permissible difference or not to display the result of the decision on the display means 32.
