CPS Electroless Plating Bench 

Electroless plating, also known as chemical plating or autocatalytic plating, is a class of industrial chemical processes that create metal coatings on various materials by a single chemical reaction of metal cations in a liquid bath.

The CPS Electroless Bench, consists of a 6 station wet cleaning and electroless plating process, with 3 pre-treatment stations and 3 electroless plating stations respectively. This process is commonly used in semiconductor manufacturing or other high technology products. 

Each cleaning station consists of an acid etching tank and DI (de-ionized) water used in e rinsing tank, to ensure a high level of cleanliness.

  Air sparge supply achieved by three Almatec series E pumps located at the rear of the bench

The de-Ionizing water supply is controlled from the front control panel, along with air sparge to tanks to each station and Each station has an operator panel which controls:

  • The supply of de-ionized water
  • The operation of an air sparge, which increases the efficiency of the wet etching process
  • Solenoid activated tank drain.

Each electroless plating plants have solution conductivity probes linked to a Walchem Plating Solution controller and thermocouples linked to a Braude Thermaster temperature controller.


  • PRTD sensor
  • capillary or compensating cable
  • no moving parts 
  • Permanent clear display of solution temperature 
  • Relay operation: 3 & 3 wire output, break on rise (std) or make on rise* 
  • Simple set point adjustment 
  • Easy to calibrate: set temperature plugs available 
  • Range -10°C to +110°C, ±1°C accuracy 
  • “Heater on” display “Probe fault” indication 
  • Dimensions: 125mm x 125mm x 75mm deep

Solution Control is achieved by using a Walchem WCU410 series controllerThe WCU410 series copper controllers are optoelectronic on-line analyzers that may be used in variety of applications such as;

  • Electroless copper baths
  • Microetch
  • Multiple chemistries that contain more than 0.10 grams/litre (g/L) of copper ions. 
  • Four control relays are available that may be set up to feed chemicals, or as alarms.
  • A fifth relay is used as a diagnostic alarm. 
  • Isolated 4-20 mA output
  • Any set point may be viewed without interrupting control. 

Bench fumes are managed by a common extraction ducting located at the rear of the bench

CPS Electroless Plating Benches are used in the manufacturing process of the following industries

  • Semiconductor
