Abstract
A heat sink includes a plurality of layers being disposed substantially parallel with a surface of a heat source. The layers include a plurality of pin portions spaced apart from each other in a planar arrangement wherein the pin portions of the layers are stacked and bonded to form pin fins extending in a transverse direction relative to the heat source to sink heat. A compliant layer is disposed between the pin fins and a mechanical load. The compliant layer provides compliance such that the pin fins accommodate dimensional differences when interfacing with the heat source.
