Abstract:
A probe card in an automated test equipment (ATE) is disclosed. The probe card may be a portion of a vertical-type probe card assembly in which pads on a circuit board are contacted by probe pins, with vertical vias in the circuit board interconnecting various conductive elements. Disclosed herein is a transposed via arrangement within a circuit board for a probe card, where adjacent vias are offset towards each other such that the inductance between the adjacent vias may be reduced to provide a desirable impedance during high frequency signal and/or power transmission.
