Abstract
A device can comprise a plurality of layers stacked and bonded on one another, wherein at least one layer of the plurality of layers comprises: a first active region comprising first pin portions positioned in a first planar arrangement; and a second active region comprising second pin portions positioned in a second planar arrangement, wherein the second planar arrangement is different from the first planar arrangement. The device can also comprise a conformable layer adjacent to at least one of the plurality of layers.

A heat sink, comprising:
- a first active region comprising first pin portions having first links connecting some of the first pin portions, and
- a second active region comprising second pin portions having second links connecting some of the second pin portions, wherein the first active region has a first ratio of the first pin portions to the first links that is different than a second ratio of the second pin portions to the second links of the second active region.
An apparatus, comprising:
- at least one layer adapted to couple to a heat source, wherein the comprises:
- a first active region comprising first pin portions having first links connecting some of the first pin portions,
- a second active region comprising second pin portions having second links connecting some of the second pin portions, wherein the first active region has a first ratio of the first pin portions to the first links that is different than a second ratio of the second pin portions to the second links of the second active region.
A method comprising:
- bonding a plurality of layers of together to form a heat sink, wherein the plurality of layers comprise a first layer comprising:
- a first plurality of pin portions;
- a first active region comprising first pin portions of the first plurality of pin portions having first links connecting some of the first pin portions, and
- a second active region comprising second pin portions of the first plurality of pin portions having second links connecting some of the second pin portions, wherein the first active region has a first ratio of the first pin portions to the first links that is different than a second ratio of the second pin portions to the second links of the second active region.
