Controller for electroless nickel baths

Nickel controller with flow-through sensor Nickel controller with flow-through sensor

Walchem's WNI Nickel Controllers are optoelectronic on-line analyzers that measure the actual concentration of nickel in solution.



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 data logging is available to validate system performance. With a USB memory stick data and event logs that include nickel measurements, and relay status can be extracted. Download logs from the USB stick to a PC.

Product features:

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 adjustable. An interlock feature allows external devices (such as a flow switch) to interlock control relays.

Integrated Data Collection

Download stored data from the controller to a USB stick. Use the data to simply and easily validate system performance. The data and event logs show nickel values, as well as accumulated chemical feed and relay activation times.

Optional pH Input Board

May be used to add pH adjustment chemistry. Output has a replenishment totalizer which may be set in units of time or volume.

Controller for electroless copper baths

WCU410 copper controller with immersible sensor WCU410 copper controller with immersible sensor

Walchem's WCU410 Copper Controllers are optoelectronic on-line analyzers that measure the actual concentration of copper in solution.



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.

 

Integrated datalogging is available to validate system performance. With a USB memory stick data and event logs that include copper measurements, and relay status can be extracted. Then download logs from the USB stick to a PC.

Four Separate Control Relays & Outputs

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.
