Disclosed is a probe card assembly which includes an interface card having a plurality of contact pads on at least one surface thereof, a probe card having a plurality of contact pads on at least one surface thereof, and a carousel interposed between the interface card and the probe card having a plurality of connecting means for making contact between the interface card contact pads and probe card contact pads. Also disclosed are the probe card, interface card and carousel as separate articles of manufacture.

Interface card for a probe card assembly

Disclosed is a probe card assembly which includes an interface card having a plurality of contact pads on at least one surface thereof, a probe card having a plurality of contact pads on at least one surface thereof, and a carousel interposed between the interface card and the probe card having a plurality of connecting means for making contact between the interface card contact pads and probe card contact pads. Also disclosed are the probe card.

Probe card assembly having a ceramic probe card

A carousel for a probe card assembly which includes opposed planar rings supported and spaced apart by flexible supports. The flexible supports, while supporting the planar rings, also allow the planar rings to rotate with respect to each other. Also included are a plurality of connecting means which pass through perforations in the planar rings so as to thereby make interconnection between a probe card and an interface card in a semiconductor test system.

Probe card assembly

A heat exchanger includes a housing, a reservoir comprising a solid material mounted within the housing, temperature control means for controlling the temperature of the reservoir, and energy exchange means for allowing thermal contact between the reservoir and a substance for effectuating transfer of energy from the reservoir to the substance for regulating the temperature of the substance.

Heat exchanger

A transfer device especially suitable for transferring a minute electronic component part from a first location and position to a second location and position, the component part having critical facet sides of high integrity and at least one non-critical side, is disclosed. The transfer device comprises a non-destructive engaging means, a control means, and a decoupling means, whereby the integrity of the essential facet sides of the component part is maintained.

Magnetic transfer device

An apparatus for producing aerosol from a substance includes a heat exchanger for receiving and cooling a substance. The heat exchanger includes a housing; a cryogenic reservoir comprising a solid material mounted within the housing; temperature control means for controllably cooling the reservoir; and energy exchange means for allowing thermal contact between the reservoir and the substance for effectuating transfer of cooling energy from the cryogenic reservoir to the substance for controllably cooling the substance. A delivery line has an inlet for receiving the substance from the heat exchanger at a first pressure. A nozzle is connected to the delivery line for receiving the substance from the delivery line. The nozzle has at least one exit opening which allows passing of the substance therethrough for expanding the substance from the first pressure to a second pressure which is lower than the first pressure for solidifying the substance and producing aerosol. Condensation preventing means is provided for preventing condensation from forming on the delivery line and/or on the nozzle.

Nozzle apparatus for producing aerosol

An apparatus and method for cleaving GaAs laser bars from a cell utilizes a first jaw applied to one end of a laser bar to propagate a cleavage and a second jaw applied to an opposite end which provides a biasing force that assures separation of the bar from the cell along the same crystallographic plane. The apparatus may be used in an ultra-high vacuum environment and allows handling of the bars without contacting the vital areas of the top surfaces or facet faces. The apparatus precisely locates bars after cleavage so that they may be further processed.
