Ⅰ.Introduction:

CN-851 is a nickel-phosphorus alloy chemical plating solution, which Rev-Plating capability is good and the solution stability is excellent, The plating layer phosphorus contain is stable, The plating layer is good compactness, excellent corrosion resistance, low internal stress and good appearance;With Auto-add device and prevent precipitation device, can be certain of the stable deposits velocity and uniform plating layer, and suitable for continuous operation. Satisfy customer in soldering, Bonding and low surface resistance performance requirements etc.
