    摘要: A probe card assembly can include a probe head assembly having probes for contacting an electronic device to be tested. The probe head assembly can be electrically connected to a wiring substrate and mechanically attached to a stiffener plate. The wiring substrate can provide electrical connections to a testing apparatus, and the stiffener plate can provide structure for attaching the probe card assembly to the testing apparatus. The stiffener plate can have a greater mechanical strength than the wiring substrate and can be less susceptible to thermally induced movement than the wiring substrate. The wiring substrate may be attached to the stiffener plate at a central location of the wiring substrate. Space may be provided at other locations where the wiring substrate is attached to the stiffener plate so that the wiring substrate can expand and contract with respect to the stiffener plate.

    摘要: By segregating at least a substantial portion of the power connections to the space transformer component (506, 700, 800) from the signal connections thereto, constraints on the interposer component (504) may be relaxed. This is particularly advantageous in the context of probing one or more high power semiconductor components. The technique of the present invention provides for a plurality of signals (including power and ground) to be inserted into an electronic component such as a space transformer both from a one main surface thereof and an edge (periphery) thereof to an opposite main surface thereof. The space transformer includes pads (522, 706, 810) for engaging, by means of spring elements (524), component (508) to be tested and includes exposed edge pads (750, 804, 854) for engagement by a flexible cable (752) for transmission of power and ground signals to the space transformer. The system also includes an interposer (504) having resilient contacts (514, 516) for electrically interconnecting a probe card (502) to the space transformer (506).
