i ■ A ■ „ WCU410 and WNI410 I Electroless Copper & Nickel Controllers An Iwaki America Company Walchem's WCU410 Copper Controller and WNI Nickel Controller are opto- electronic 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 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. The WNI41 0 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! Concentration Read in Units Selectable between grams per liter (g/L) or ounces per gallon (oz/gal). Backlit digital display also acts as a bar graph for a continuous "visual summary" of measurement versus set point. Operator Adjustable Concentration set point, alarm set points (high and low), dead band and pump on time are all easily adjustable. An interlock feature allows external devices (such as a flow switch ) to interlock control relays. Simple, Integrated Data Collection Download stored data from the controller to a USB stick. Use the data to simply and easily P* validate system performance. The data and event logs show copper or nickel values, as well as accumulated chemical feed and relay activation times. Four Separate Control Relays & Outputs (WCU) May be used to add copper, caustic, formaldehyde or chelator/stabilizer chemistries. Each output has a replenishment totalizer which may be set in units of time or volume. Optional pH Input Board (WNI) May be used to add pH adjustment chemistry. Output has a replenishment totalizer which may be set in units
