copper anode

详情

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, C**2, C**0, and C**2. PCB industry grade composition (%): Cu: *9.*4min P: 0.***4 Pb: 0.***6 max.
