  • Patent number: 11404350
    Abstract: A heat sink mounting configuration is provided that is configured to prevent the heat sink from damaging ball grid arrays (BGA) of an application specific integrated circuit (ASIC) mounted on a printed circuit board (PCB) when the line card is subjected to vibrations and shocks. The heat sink mounting configuration may include a set of screws configured to be at least partially disposed within the apertures of the heat sink to secure the heat sink to the PCB. The mounting configuration includes a resilient member and a spacer disposed around the screws proximate to the apertures. The resilient members are configured to bias the heat sink against the ASIC to maintain the heat sink in contact with the ASIC. The spacers are configured to prevent the heat sink from impacting the ASIC with forces large enough to damage the BGA when the line card is subjected to vibrations and shocks.

  • Patent number: 10903140
    Abstract: A circuit board includes a heatsink configured to be coupled to the circuit board via a first coupling mechanism, the first coupling mechanism providing an asymmetrical downward force for coupling the heatsink to the circuit board. The circuit board further includes a second coupling mechanism configured to provide a counter force to the asymmetrical downward force of the first coupling mechanism. The counter force can be configured on an overhang portion of the heatsink that does not cover a circuit on the circuit board.

  • Publication number: 20070111550
    Abstract: A cable assembly comprising a hollow sleeve, an electrical conductor within the hollow sleeve, and first and second connectors on opposing ends of the electrical conductor that are fastened to opposing ends of the sleeve. The first connector is adapted to blind-mate to a corresponding connector in a cabinet backplane and the second connector is adapted to couple to an electronic device to be installed in the cabinet. Power is provided from the backplane to the electronic device via the electrical conductor. The hollow sleeve is disposed within a tunnel supported by the cabinet. The hollow sleeve has a length greater than that of the tunnel such that the first connector protrudes from a first opening of the tunnel and the second connector protrudes from a second opening of the tunnel.
