Walchem - WCU410 and WNI410 Electroless Copper Controllers

Walchem - WCU410 and WNI410 Electroless Copper Controllers

Features & Specifications:

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 micro etch baths (including oxide-replacement types).

The WCU may be switched from electroless copper to micro etch via the menu, eliminating the need for a second controller. It reduces the need for manual titration, improves yield, and in micro etch applications improves productivity by reducing the frequency of bath change-outs.

The WNI 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.
