  • Patent number: 6116915
    Abstract: An information handling system includes stacks of printed circuit boards interconnected using an interconnection system. The printed circuit boards include network boards, system interface boards, memory boards, and central processing unit boards. The interconnection system for electrically connecting the various printed circuit boards includes a set of interconnection modules placed adjacent one another to form a substantially aligned row. The interconnection modules can be used to connect one stack to an orthogonally oriented stack or to a parallel oriented stack. The printed circuit board used in the interconnection system includes an inner rail positioned near the edge of the printed circuit board, an outer rail positioned near the edge of the printed circuit board, and an alignment stop attached to or positioned near one of the inner or outer rail. The most distant interconnection module of a row of aligned modules includes a spring attached thereto.

  • Patent number: 6012928
    Abstract: A circuit card connector that utilizes flexible circuitry includes an elongated base, a pair of cradle spring members supported on the base, and a pair of contact springs movably supported on the cradle spring members. The cradle spring members include a plurality of reset arms that extend upwardly therefrom into contact with the undersides of the flexible circuitry. The flexible circuitry includes an apertured ground plane layer spaced apart from and located beneath the signal face layer. The apertures in the ground plane layer increase its flexibility especially at the interconnection interfaces to increase the compliance of the connector.

  • Patent number: 5911584
    Abstract: A circuit card connector that utilizes flexible circuitry includes one or more isolator portions attached to its base that serve to substantially isolate the base of the connector from the circuit board to which the connector is mounted. The isolator portions include feet that extend out from the connector and which partially support the flexible circuitry. These isolator portions are made from thermally insulative material and serve to prevent heat transfer to the connector base from occurring during soldering of the flexible circuitry conductive portions to the circuit board.
