A probe card consists of a circular printed circuit board (PCB) with attached probe pins or probe needles. Each LSI chip, fabricated on a wafer, is electrically inspected with the simultaneous contact of multiple probe pin tips arranged on the PCB. Probe cards detect opens and short circuits and also measure electric current and high frequencies.
