    Abstract: 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).

    Abstract: Interconnection elements and/or tip structures for interconnection elements may first be fabricated upon sacrificial substrates for subsequent mounting to electronic components. In this manner, the electronic components are not `at risk` during the fabrication process. The sacrificial substrate establishes a predetermined spatial relationship between the interconnection elements which may be composite interconnection elements having a relatively soft elongate element as a core and a relatively hard (springy material) overcoat. Tip structures fabricated on sacrificial substrates may be provided with a surface texture optimized for mounting to any interconnection elements for making pressure connections to terminals of electronic components. Interconnection elements may be fabricated upon such tip structures, or may first be mounted to the electronic component and the tip structures joined to the free-ends of the interconnection elements. Tip structures formed as cantilever beams are described.

    Abstract: Techniques for testing an electronic device with through-device vias can include using a probe card assembly with probes for contacting connection structures of the electronic device including ends of through-device vias of the electronic device. A pair of the probes can be electrically connected in the probe card assembly and can thus contact and form a direct return loop from one through-device via to another through-device via of a pair of the through-device vias with which the pair of probes is in contact. The electronic device can include test circuitry for driving a test signal onto the one of the through-device vias and a receiver for detecting the test signal on the other of the through-device vias.

    Abstract: A probe head can comprise a substrate and electrically conductive structures extending from opposite surfaces of the substrate. The probe head can be made by forming frame structures each comprising a frame to which a row of the conductive structures is coupled. The frame structures can be placed in a stack. A compressible shim or a curable adhesive can be provided between adjacent frames in the stack to control a distance between the contact ends of the conductive structures in adjacent rows of the conductive structures. The frames can include cavities that form a mold while the frames are in the stack, and the substrate can be formed by introducing a moldable material into the mold. After the moldable material hardens, the frame can be removed, leaving the conductive structures embedded in the substrate.
