  • Patent number: 7333333
    Abstract: A heat dissipation device includes a heat sink, a retention module and a clip. The retention module includes a plurality of locking portions. The clip includes a main piece, an operating piece pivotally connecting with the main piece, and a buckling piece pivotally connecting with the operating piece. The main piece includes a pressing beam resting on the heat sink and a clamping portion engaging with a corresponding locking portion of the retention module. By operating the operating piece, the heat dissipation device has two positions, at a first of which a clamping portion of the buckling piece engages with a corresponding locking portion of the retention module and the pressing beam of the main piece presses the heat sink toward the retention module; at a second of the two positions, the clamping portion of the buckling piece disengages from the retention module.

  • Patent number: 7304381
    Abstract: In some embodiments, an integrated circuit package includes a substrate and a heat spreader coupled to the substrate by fasteners. Thermal interface material thermally couples the die to the heat spreader. The heat spreader is provided over the die and is attached to the substrate with fasteners rather than a sealant-adhesive. Some examples of suitable fasteners may include rivets, barbed connectors, and gripping clips.

  • Patent number: 7292447
    Abstract: A back plate assembly (100) for a board (200) comprises a back plate (110) abutting against a side of the board and a plurality of posts (120). Each post comprises at least one latching portion (1206) formed thereon. After the latching portions have passed through the back plate and the board, the latching portions are blocked by one of the board and the back plate to secure the back plate to the board. Screws (330) are used to extend through a heat sink (300) to threadedly engage with the posts thereby mounting the heat sink to the board. Thus, the heat sink can have an intimate contact with an electronic component (210) mounted on the board.

  • Patent number: 7289330
    Abstract: A heat sink assembly (100) includes a heat sink (10) having a plurality of fins (14), a fan handle (24) buckled with the fins and a fan (30) mounted on the heat sink (10) via the fan handle. The fan handle includes a retaining body (26) clasping two adjacent fins having a space therebetween. A screw (22) is extended through the fan and into the space of the two adjacent fins. The retaining body includes a pair of opposite lateral walls (260) clamping opposite sides of the two adjacent fins, for preventing the two adjacent fins from being over expanded outwardly during the insertion of the screw into the space.

  • Publication number: 20060115975
    Abstract: A method for attaching an IC package to a circuit board, the IC package having a plurality of electrical contacts in an arrangement having a perimeter, first positions the IC package adjacent to the circuit board. Then, electrically connects the IC package to the circuit board through the plurality of electrical contacts. The method finally, disposes at least one anchor mechanically attaching the IC package to the circuit board, the anchor disposed at a location outside of the perimeter of the plurality of electrical contacts. The type, quantity, and exact geometry of the anchors depend on the specific design parameters of the IC package and circuit board.

  • Patent number: 6870258
    Abstract: A fixture suitable for coupling a lid to a substrate having a semiconductor chip coupled thereto and a method for coupling the lid to the substrate. A support structure has a cavity having a floor and a pedestal protruding from the floor. A guide extends from the support structure. A compression mechanism is coupled to the guide wherein the compression mechanism includes an actuator plate coupled to a compression plate by a compressible means. An actuator is coupled to the compression mechanism. A packaging substrate having a semiconductor chip is mounted to the packaging substrate and a lid is mounted over the semiconductor chip to form a semiconductor component. The semiconductor component is placed on a support structure and the actuator is activated to urge the compression plate to apply a uniform force against the lid.
