  • Patent number: 6234321
    Abstract: Automatic semiconductor part handler. In one aspect the handler includes a source of parts and a transfer mechanism for transferring a part from the source to a belt assembly. The belt assembly includes a belt, a belt displacement controller, and an image forming device for forming an image of the part with respect to a desired end point. The belt displacement controller is coupled to the belt to move the belt based upon the image of the part with respect to the desired end point, thereby positioning the part in a precise location with respect to the direction of motion of the input belt.

  • Patent number: 5177436
    Abstract: A contactor including a test fixture for receiving an integrated circuit chip mounted in a carrier package and for providing contacts with electrical conductor pads of the package to facilitate electrical testing thereof is provided. The test fixture comprises a plurality of contact members mounted to a spring-loaded plunger. Each contact member includes a strip of conductive fingers with protruding contacts for springing engagement with the conductor pads of the carrier when the plunger is depressed. The test fixture resides in a cavity of a housing unit and is aligned with a central aperture therein. In operation, a ram holding the carrier lowers it through the central aperture of the housing unit and onto the plunger. The carrier is then pressed against the plunger, causing it to depress. This allows the carrier conductor pads to frictionally engage the protruding contacts of the conductive fingers, thus effectuating electrical contact.

  • Patent number: 4686468
    Abstract: A planar contact set for use in a test fixture for receiving an integrated circuit package for facilitating the electrical connection thereof to test equipment so that electrical and electronic tests can be performed on the integrated circuit. The contact set includes a flexible insulating support member having a central aperture which supports a plurality of conductive contact strips which extend over the aperture in cantilever fashion. The support member includes a support sheet underlying the contact strips and a retaining sheet overlying the contact strips, the sheets maintaining the strips in the proper position to contact the leads of the integrated circuit package when in a test registration position and also to enable electrical connections to be made to the test apparatus.
