The printed circuit board is essentially the most important component part of all
electronic instruments. In addition, high quality copper anode is a key factor
in the manufacture of high-grade PCBs. Therefore, we have introduced a whole set
of advanced production equipment with technology transferring that meets American
Federal Copper Development Association standards.

After strict testing, our copper anode has fine grain structure, even distribution,
and is free of gas and residues. Product quality matches or exceeds American
Commonwealth Copper Development Bureau standards CDA, C812, C120, and C122.
