A probe card for use in testing a wafer and a method of making the probe card include a printed circuit board (PCB) formed with a conductor pattern and a probe head in proximity to the PCB, the probe head defining at least one hole through the probe head, and the probe head being made of an electrically insulating material. At least one conductive pogo pin is disposed respectively in the at least one hole, the pogo pin having a first end electrically connected to the conductor pattern on the PCB. At least one conductive probe pin includes a cantilever portion and a tip portion. The cantilever portion is in contact with and electrically connected to a second end of the pogo pin, and the tip portion is electrically connectable to the wafer to electrically connect the wafer to the conductor pattern on the PCB. The cantilever portion of the probe pin is fixedly attached to the probe head.
