  • Patent number: 8462508
    Abstract: A heat sink comprises a vapor chamber base formed in a three-dimensional arrangement that mirrors topology of underlying structures on a substrate upon which the heat sink can be mounted, and at least one fin coupled to the vapor chamber base.
    Type: Grant
    Filed: April 30, 2007
    Date of Patent: June 11, 2013
    Assignee: Hewlett-Packard Development Company, L.P.
    Inventors: Robert J. Lankston, II, Christopher G. Malone, Stephen D. Cromwell
  • Patent number: 7926552
    Abstract: An apparatus comprising a heat dispersion device having a first end. The first end has a shape different than that of the remainder of the heat dispersion device. The apparatus also comprises a jacket coupled to the heat dispersion device at the first end. The jacket has another shape associated with that of the remainder of the heat dispersion device.
    Type: Grant

  • Patent number: 6930884
    Abstract: Disclosed is land grid array (LGA) assembly using a compressive load. An LGA assembly includes a first component located on the top of the LGA assembly; a center load screw coupled to the first component; and a second component, wherein the center load screw is received on the second component upon turning the center load screw in a first direction. Further turning of the center load screw in the first direction after the center load screw is received on the second component, operates the first component to apply a compressive load within the LGA assembly.

  • Patent number: 6724629
    Abstract: An integrated circuit attachment implementation includes a mechanism for inserting and securely holding a replaceable component to an integrated circuit. The mechanism includes a top plate, leaf springs in contact with the top plate, a leaf spring cradle that carries the leaf springs, with the cradle including upper projections that project through corresponding slots in the top plate, a pin inserted through openings in the upper projections, and a linear slide cam located on an upper surface of the top plate between the upper projections and further located below the pin. The cam operates in a first position to transfer a load the replaceable component to securely hold the replaceable component to the integrated circuit and a second position to allow placement of the replaceable component on the integrated circuit.
