Claim:
1. A printed circuit board (PCB) for use with a cooling device configured to cool at least one device, the at least one device being at least one of an electronic device, an optical device, an electro-optic device, and a magnetic device, the PCB comprising: a substrate having a first surface and a second surface opposing the first surface; a ground plane on the first surface of the substrate, the ground plane including a patterned-region that is patterned with an array of holes with some desired ratio of metal to gap; and circuitry in a circuit-region on the second surface of the substrate, the circuitry configured for use with the at least one device to be cooled, wherein, when a first side of the cooling device contacts the ground plane, and when the at least one device to be cooled contacts the circuitry, a reduced cross-sectional area of the patterned-region in the ground plane increases the thermal resistance of the patterned-region reducing thermal transfer, thereby reducing degradation of a performance of the at least one device.
