摘要：
A probe card interface for interfacing a probe head with a first circuit. The probe card interface includes an impedance control element to interface a first set of pins of the probe head with the first circuit. The impedance control element is further configured to control the impedance of the first set of pins. The probe card interface includes a conductive plane to interface a second set of pins of the probe head with the first circuit. The conductive plane is further coupled to provide at least one of power or ground to the second set of pins.
