APPARATUS FOR EVALUATION TEST OF CAPACITY PERFORMANCE

摘要

PURPOSE:To obtain the performance evaluation data of a unit substrate, by automati cally changing over the application mode of testing energy applied to an electric unit substrate. CONSTITUTION:From the aspect of the evaluation of performance, CPU111 performs the change-over control of six parameters of the application level of an electrostatic noise, the application quantity level of charge, the application time interval of charge, the application number of times, a protective resistance value and an electrostatic noise applying position to obtain test data. That is, the electrostatic noise applying point P1 of a substrate 118 tested is selected by supplying a relay control signal SRL to a relay 117 and connecting said point P1 to a contact T1. In a protective resistance part 116, a resistor R1 is selected by a resistor change-over signal SPR. The time intervals of charge and discharge due to the opening/closing of opening/closing switches 112, 113 and the initial state of the number of times of charge and discharge are set and a capacitor C1 is selected by a capacitor selecting signal SC. Further, the voltage EVR of a DC power source 115 is set to initial predetermined voltage by a voltage variable signal SE. Succeedingly, various test data corresponding to each set state can be obtained within a short time by various change-over signals from CPU111.
