  • 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: 7324344
    Abstract: A heatsink attachment assembly includes a first anchor, a second anchor and a heatsink clip. The first anchor is configured to insert into a first hole in a circuit board in an upward direction from an underside of the circuit board toward a topside of the circuit board. Similarly, the second anchor is configured to insert into a second hole in the circuit board in the upward direction. The heatsink clip has (i) a first end configured to fasten to the first anchor when the first anchor is inserted into the first hole in the circuit board, (ii) a second end configured to fasten to the second anchor when the second anchor is inserted into the second hole in the circuit board, and (iii) a middle section configured to provide force on a heatsink in a downward direction which is substantially opposite the upward direction.

  • Patent number: 7321493
    Abstract: An improved heatsink attachment assembly includes a first anchor configured to secure to a first location of the circuit board, and a second anchor configured to secure to a second location of the circuit board. Each anchor includes legs having looped end portions configured to contact the circuit board. The heatsink attachment assembly further includes a heatsink clip configured to concurrently (i) fasten to the anchors when the anchors secure to the circuit board, and (ii) hold a heatsink to against a circuit board component of the circuit board. The looped end portions of the legs prevent the legs from completely passing through holes defined in the circuit board. In some situations, the looped end portions define extended coils (e.g., double loops) for a robust interference fit with the circuit board as well as for enhanced strength and stability.

  • Patent number: 7088586
    Abstract: A dimpled heat spreader includes a central portion configured to couple to the circuit board component, an outer portion coupled to the central portion, and dimpled portions disposed within the outer portion. The outer portion is configured to extend from the central portion and support the dimpled portions beyond a footprint of the circuit board component when the central portion couples to the circuit board component. The dimpled portions of such a heat spreader provides more exposed surface area (e.g., per square inch) than conventional heat spreaders with flat end portions for improved and enhanced heat dissipation via natural convection into the ambient air. Moreover, a heat spreader with such dimpled portions is relatively easy and cost effective to make vis-à-vis more complex structures such as fins or posts thus enabling a manufacturer to produce dimpled heat spreaders using a high volume, low cost assembly process.

  • Patent number: 7064957
    Abstract: A heat sink attachment mechanism includes a fastener having an associated compressible member. The fastener defines a flange that, as the fastener secures a heat sink to a circuit board component, is configured to contact a circuit board surface associated with the circuit board component. Contact between the flange and the circuit board minimizes the travel of the fastener relative to the circuit board component and limits the stress generated on the circuit board component or on the solder balls of a ball grid array associated with the circuit boards component by the heat sink. Also, as the fastener secures the heat sink to the circuit board component, the fastener compresses the compressible member against the heat sink, thereby causing the compressible member to expand. Expansion of the compressible member allows the compressible member to absorb changes in the stress applied by the fastener to the heat sink and circuit board component over time.
