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 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!
