摘要： A probe card includes a printed circuit board (PCB) and a probe ring coupled to the PCB. The probe card further includes a plurality of probes coupled to the PCB and to the probe card, and includes a plurality of tubes respectively associated with the plurality of probes. Each tube is configured to surround at least a portion of the probe that the tube is associated with. Each tube includes an inner dielectric portion and an outer conductive portion. The conductive portion of each tube is electrically coupled to the PCB.
