Purity:99.8%
Crystalline Structure
Electrodeposited copper crystals tend to grow lengthwise in the Z-axis of the foil. Typically, a polished section of
electrodeposited copper foil has the appearance of a picket fence, with long crystal boundaries perpendicular to
the foil plane. Rolled copper crystals are broken and crushed during the cold rolling operation. They are smaller
than the electrodeposited crystals, and have irregular, spherical shapes, nearly parallel to the foil plane.
Manufacturing Process:
In an electrodeposited copper manufacturing process, the copper foil is deposited on a titanium rotating drum from a copper solution where it is connected to a DC voltage source. The cathode is attached to the drum and the anode is submerged in the copper electrolyte solution. When an electric field is applied, copper is deposited on the drum as it rotates at a very slow pace. The copper surface on the drum side is smooth while the opposite side is rough. The slower the drum speed, the thicker the copper gets and vice versa. The copper is attracted and accumulated on the cathode surface of the titanium drum. The
matte and drum side of the copper foil go through different treatment cycles so that the copper could be suitable for PCB fabrication. The treatments enhance adhesion between the copper and dielectric interlayer during copper clad lamination process. Another advantage of the treatments is to act as anti-tarnish agents by slowing down oxidation of copper.
Application:
1. Polyimide board
2. Epoxy board
