Walchem’s WCU Copper Controller and WNI Nickel Controller are optoelectronic on-line analyzers that measure the actual concentration of copper or nickel in solution. They are used in a variety of applications including electroless plating baths and microeth baths (including oxide-replacement types).

WCU COPPER CONTROLLER

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, and in microetch applications improves productivity by reducing the frequency of bath change-outs.

WNI NICKEL CONTROLLER

|

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 totalizing either pump on-time, volume pumped, or metal turnovers.

Integrated datalogging is available 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.
It couldn’t be easier!
