Classification: CPC H | IPC H

Claim 0:
1. A printed circuit board (PCB), including:
a processing unit;
a plurality of layers; and
a plurality of vias, each via extending through two or more of the layers, wherein
a first via of the plurality of vias has a first pad at a first layer of the plurality of layers,
a second via of the plurality of vias has a second pad at the first layer of the plurality of layers,
a third via of the plurality of vias has a third pad at a second layer of the plurality of layers,
a fourth via of the plurality of vias has a fourth pad at the second layer of the plurality of layers,
the first, the second, the third, and the fourth pads are unused ground pads, wherein the first layer is spaced-apart from the second layer,

a plurality of bridging connectors, wherein
a first bridging connector of the plurality of bridging connectors extends only between the first via and the second via, the first bridging connector connecting the first pad at the first via with the second pad at the second via to form a first heatsink at the first layer that dissipates heat away from the processing unit, and
a second bridging connector of the plurality of bridging connectors extends only between the third via and the fourth via, the second bridging connector connecting the third pad at the third via with the fourth pad at the fourth via to form a second heatsink at the second layer that dissipates heat away from the processing unit.
