  • Power supply assembly for a semiconductor circuit tester
    Patent number: 7292059
    Abstract: A power supply assembly includes a dielectric substrate and a power supply circuit supported by the dielectric substrate. A conductive connection block is attached to the dielectric substrate at a main surface thereof and is connected to a power supply terminal of the power supply circuit. A spring probe pin is fitted in a bore formed in the connection block and includes a conductive sleeve and a conductive plunger fitted in the sleeve. The conductive sleeve is in electrically conductive contact with the connection block.

  • Power supply arrangement for integrated circuit tester
    Patent number: 7084659
    Abstract: A test head for a semiconductor integrated circuit tester, the test head includes a power supply board mounted to a power distribution board and positioned between the power distribution board and a device interface board. The power supply board includes a power supply circuit having power supply input terminals for receiving electrical power at a voltage Vin and force and return terminals for supplying regulated electrical power at a voltage Vout. The power supply board further includes a power connector for connecting the force and return terminals of the power supply circuit to power supply contact elements of the device interface board.

  • Controlled-impedance coaxial cable interconnect system
    Patent number: 6951482
    Abstract: An interconnection structure includes a positioning block and a dielectric substrate. A coaxial cable has an end segment that is fitted in a passage in the positioning block and the positioning block is so positioned relative to the dielectric substrate that an end face of the inner conductor of the coaxial cable is presented towards a conductive element on a main face of the substrate. A discrete resilient contact element is interposed between the end face of the inner conductor and the conductive element and in electrically-conductive pressure contact with both the inner conductor and the conductive element.
