Patent ID: 7298623

Claim:
A substrate heat transfer apparatus, comprising: a conductor-carrying substrate having a top surface, wherein one or more cut-out channels are formed on the top surface of the substrate; a cover layer provided on the top surface of the substrate, wherein the cover layer encloses the one or more cut-out channels to form one or more thermal dissipation channels, and wherein the one or more thermal dissipation channels are in fluid communication with an input port and an output port; wherein the top surface of the substrate includes attach pads arranged in rows and exposed through the cover layer, and wherein at least a portion of a first one of the one or more thermal dissipation channels extends along the entire extent of a first row of the attach pads, and wherein the cover layer overlies in a sealed relationship a portion of each of the attach pads in the first row so that an upper surface of the first one of the one or more thermal dissipation channels is at least partially defined by the sealed combination of the cover layer and the attach pads in the first row.
