    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).

    摘要: 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.

    摘要: An electronic device is moved into a first position with respect to probes for making electrical contact with the device. The electronic device is then moved into a second position in which the electronic device is pressed against the probes, compressing the probes. The movement into the second position includes two components. One component of the movement tends to press the electronic device against the probes, compressing the probes and inducing a stress in the probes. The second movement tends to reduce that stress. Test data are then communicated to and from the electronic device through the probes.

    摘要: A carbon nanotube contact structure can be used for making pressure connections to a DUT. The contact structure can be formed using a carbon nanotube film or with carbon nanotubes in solution. The carbon nanotube film can be grown in a trench in a sacrificial substrate in which a contact structure such as a beam or contact element is then formed by metal plating. The film can also be formed on a contact element and have metal posts dispersed therein to provide rigidity and elasticity. Contact structures or portions thereof can also be plated with a solution containing carbon nanotubes. The resulting contact structure can be tough, and can provide good electrical conductivity.
