PROBE CARD

摘要

In some embodiments, a probe card includes a PCB, a substrate, a pair of probes, a capacitive device and a first part. The PCB includes a pair of conductive paths through a first surface and a second surface of the PCB. The substrate includes a pair of conductive paths through a first surface and a second surface of the substrate. The conductive paths of the substrate and the corresponding conductive paths of the PCB are coupled between the first surface of the substrate and the second surface of the PCB. The probes and the corresponding conductive paths of the substrate are coupled beyond the second surface of the substrate. The capacitive device is coupled between a first conductive path and a second conductive path through the PCB, the substrate and the probes. The first part is configured beyond the second surface of the PCB, and holds the capacitive device.
