ELECTRICAL DIE SORTING TEST SYSTEM TO REDUCE TIME REQUIRED TO MEASUREMENT BY MONITORING VOLTAGE IN REAL TIME

摘要

PURPOSE: EDS(Electrical Die Sorting) test system is provided to reduce the time and the man power required to measurement by monitoring a voltage in real time with a voltage measuring device. CONSTITUTION: EDS test system includes a prober system, a power supply unit and a voltage measuring device. The power supply unit is located within the prober system. The voltage measuring device measures a voltage of the voltage supply unit. The voltage measuring device comprises a measuring unit and a plurality of display units. The measuring unit is connected with voltage check terminals of the voltage supply unit and a common ground terminal. The plurality of display units connected electrically with the measuring unit monitors the respective voltage of the voltage check terminal by measuring in real time.
