Abstract
A heatsink includes a rigid plate and a plurality of pin fins. The plate has a two dimensional array of holes through the rigid plate from a first face to a second face. Each pin fin is received in one of the holes and has a proximal end extending beyond the first face of the plate for conductively receiving heat, a distal end extending beyond the second face of the plate for convective heat exchange with air, a biasing member biasing the pin fin in a proximal direction, and a shoulder limiting the proximal extension of the pin fin through the hole. An apparatus may include the pin fin heatsink secured to a printed circuit board having at least two components that have different heights. Accordingly, each component is contacted by the proximal end of one or more self-adjusting pin fins that are aligned with the component.
