Abstract
A composite copper foil () comprises a carrier foil () formed by electrodeposition onto a cathode, the carrier foil () having a cathode side formed in contact with the cathode and an opposite electrolyte side. A very thin release layer () is on the electrolyte side of said carrier foil (). A thin functional foil () formed by deposition of copper has a front side in contact with the release layer () and an opposite back side. The electrolyte side of the carrier foil () has a surface roughness Rz less than or equal to 3.5 μm. There is also presented a method for manufacturing such a composite copper foil.
