摘要： 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.

摘要： 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.

摘要： 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.
