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.
