Ultra Low Profile Copper Foil for Very Low Loss Material
A new almost no profile copper foil has been developed to achieve this property while maintaining a good adhesion with low loss resins. Electrodeposited copper foil production is divided in two steps. First, the foil is plated on a titanium drum from a copper sulfate solution. Then a treatment is applied to increase roughness and ensure oxidation resistance.
