A copper foil to provide electrical conductivity, the copper foil comprising:
- a flexible conductive surface, wherein the flexible conductive surface is formed from copper;
- a plurality of roughness nodules, wherein the roughness nodules are arranged in a predetermined pattern on the flexible conductive surface;
- and
- at least one channel located between a pair of parallel rows of roughness nodules, the at least one channel providing a conduction path along the copper foil.
An information handling system (IHS) comprising:
- a central processing unit (CPU);
- and
- random access memory (RAM) communicatively coupled with the CPU;
- wherein the CPU and RAM are communicatively coupled using a circuit structure constructed with cooper foil that includes:
- a flexible conductive surface, wherein the flexible conductive surface is formed from copper;
- a plurality of roughness nodules, wherein the roughness nodules are arranged in a predetermined pattern on the flexible conductive surface;
- and
- at least one channel extending between a pair of parallel rows of roughness nodules, the at least one channel providing a conduction path.
A method of producing copper foil having a surface on which a plurality of roughness nodules are arranged according to a predetermined pattern, the method comprising:
- providing a sheet formed from copper;
- determining, based on a predetermined pattern, distinct regions of a surface of the sheet on which to form a plurality of roughness nodules;
