Abstract
A probe card to connect a semiconductor device to test equipment includes a Printed Circuit Board (PCB) in which an electrical wiring pattern is formed, a first connector fixed on an upper surface of the PCB to connect the test equipment to the PCB, probe needles connected to electrode pads of the semiconductor device, and a Flexible PCB (FPCB) to connect the PCB to the probe needles. Accordingly, a signal transmission characteristic can be enhanced, test expenses can be reduced, and ground noise can be reduced.
