Introduction: High-Purity Copper Sulfate

In PCB manufacture industry, the layer of chemical plating usually is
thickened through an acid copper plating process. Furthermore, throwing
power and covering power of the bath are sensitive to organic impurities
and various metal impurities. It is possible to avoid taking them into the
bath if the copper sulfate is high purity.

Therefore, problems such as pits, marks, darkness and mist become easy
to forestall in order to guarantee a well-proportioned surface and plating
capacity to deep and small holes. Moreover, it helps to improve the tractility
of the board and the strength for resisting haul.
