Oak-Mitsui is recognized as the technological leader in the manufacture of high-quality electrodeposited copper foils for printed circuit board, lithium ion battery, and industrial applications. With the strength of international scope, Oak-Mitsui produces both conventional cladding and application specific copper foils required by technology's leading edge companies at our manufacturing facility in Camden, SC.

At Oak-Mitsui, copper foils are electroformed on revolving titanium drums, unique for the ability to deposit copper foils with a high-quality surface. Electroformed foils are then subjected to a variety of surface treating operations contingent upon end-use requirements. During treating, Oak-Mitsui has the capability to deposit copper dendrites onto the foil surface to enhance bonding to B-staged resins upon lamination or for uniform coating in lithium ion battery applications. A "barrier-layer" is applied to the copper foil to prevent oxidation during shipping, storage, lamination and post-bake cycles.
