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.
