Product Content Description:

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 including 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 tactility
of the board and the strength for resisting haul.
