Abstract: The present invention provides a method and structure for connecting a module to a printed circuit board, wherein a substantially rigid interposer having resilient conductors is disposed between a module and a printed circuit board. A clamping means urges the module and printed circuit board toward each other with compressive force upon an interposer positioned therebetween, preferably causing the module and printed circuit board to deform and thereby align their electrical contacts with the surfaces of the interposer. The interposer further comprises a plurality of apertures, each aperture further having a deformable resilient conductor means for connecting a module contact to a PCB contact. The conductor is deformable in shear, which may travel and, therefore, makeup the CTE dimensional mismatch between the module and the PCB. The conductors are detachable, electrically connecting the module and PCB contacts without the requirement of solder or other permanent means.

In a first embodiment, the contact structures include raised members formed over a body of the interposer. A conductive layer is formed over each of the raised members to provide a contact surface for engaging the leads of the chip package. In another embodiment, the raised members are replaced with depressions formed into the interposer. A conductive layer is formed on an inside surface of each depression to provide a contact surface for engaging the leads of the chip package. Moreover, any combination of raised members and depressions may be used.

Abstract: The present invention is drawn to a system for attaching and supporting a cable to an IO panel of an electronic component such as the IO back panel of a computer. The system is comprised of a cable dock coupled to an IO panel, with a gasket disposed within the cable dock to form a conducting path from the IO panel to the cable backshell. In particular, a cable dock is fixed to the IO panel where an IO connector is exposed. Once the cable backshell is plugged into the cable dock, the cable dock provides mechanical support for a cable assembly comprising the cable-end connector, the cable backshell and the cable. The cable assembly is secured by the cable dock rather than by the coupling made between the cable-end connector and the IO connector. The cable dock also orients the cable-end connector in coupling to the IO connector such that the cable backshell is prevented from being incorrectly plugged into the cable dock.
