Walchem 400 series process controllers for nickel and copper plating
Walchem’s copper controller and nickel controller are optoelectronic on-line analysers that measure the actual concentration of copper or nickel in solution. They are used in a variety of applications including electroless plating baths and microetch baths (including oxide-replacement types). The WCU410 may be switched from electroless copper to microetch via the menu, eliminating the need for a second controller. It reduces the need for manual titration, improves yield & in microetch applications improves productivity by reducing the frequency of bath change-outs. The WNI410 is available as nickel-only, or with a pH control option which may be added in the field. Two separate pump outputs for nickel and reducer and another for pH are used, each of which is capable of totalising either pump on-time, volume pumped, or metal turnovers. Integrated data logging to validate system performance. A USB memory stick is all that’s needed to extract data and event logs that include copper or nickel measurements, and relay status. Download logs from the USB stick to a PC at your convenience
