  • Patent number: 6939175
    Abstract: A coaxial cable for transmitting high frequency signals includes includes a body having a center conductor and a shield formed coaxially around the center conductor and separated from the center conductor by a layer of dielectric having an annular layer of electro-static-discharge polymer. The cable also includes conductive pads to engage contacts on a mating connector. At least one of the conductive pads is attached to the center conductor and at least another one of the conductive pads is attached to the shield.
    Type: Grant

  • Publication number: 20030122538
    Abstract: A tester interface assembly is disclosed for coupling a plurality of tester electronic channels to a device-interface-board. The tester interface assembly includes at least one harness assembly having a plurality of coaxial cables, each cable including a body having a center conductor and a shield. The shield is formed coaxially around the center conductor and separated therefrom by a layer of dielectric. Each cable further includes a distal tip formed substantially similar to the body and including respective formed conductive pads disposed on the distal extremities of the center conductor and the shield. The harness employs a housing formed with an internal cavity for receiving and securing the cable distal ends in close-spaced relationship such that the distal tips form an interface engagement plane. A compliant interconnect is interposed between the harness assembly and the device-interface-board, and includes a plurality of conductors formed to engage the cable distal ends along the engagement plane.

  • Patent number: 6476628
    Abstract: A semiconductor parallel tester is disclosed for simultaneously testing a plurality of DUTs secured to a handling apparatus. The test system includes a system controller for initiating system test signals and a pin electronics assembly responsive to the system test signals to generate test pattern signals for application to the plurality of DUTs. The system further includes a signal interface defining a plurality of direct signal paths between the handling apparatus and the pin electronics assembly.

  • Patent number: 6310486
    Abstract: A semiconductor tester is disclosed that is adapted for testing semiconductor devices disposed on a handling apparatus. The semiconductor tester includes a tester housing defining a self-supporting frame and formed with an externally accessible opening adapted for receiving the handling apparatus. A test controller is disposed within the housing and carried by the frame. Pin electronics including tester circuitry are responsive to the test controller and proximately coupled thereto and mounted to the frame. A docking apparatus is disposed above the opening and is adapted to couple the tester circuitry to the handling apparatus.
