Abstract:
1. A circuit card assembly, comprising: a first layer having first and second sides, at least a portion of the first layer being substantially planar in a first x-y plane, wherein the first layer comprises a first material that is electrically and thermally conductive, such that the first layer is constructed and arranged to carry electrical signals; a first insert, the first insert comprising a solid, continuous piece of pyrolytic graphite (PG) disposed between the first side and the second side of the first layer, wherein the first insert is substantially planar in the x-y direction and is constructed and arranged to have its highest thermal conductivity in the x-y plane, and wherein the first insert has an exterior surface of solid, continuous PG that is surrounded on all sides by the first layer, such that substantially all of the exterior surface of the first insert is in continuous thermal contact with the first layer, the first insert being oriented within the first layer such that the insert can dissipate heat generated by the circuit card assembly; and a second layer having first and second sides, the second layer comprising at least one of an insulating and a dielectric material, wherein the second side of the second layer is coupled to the first side of the first layer so as to overlay at least a portion of the first layer.
