Copper electroless plating in weakly alkaline electrolytes using DMAB as a reducing agent for metallization on polymer films
Copper electroless plating at low pH (7–9) using dimethylamine borane complex as a reducing agent is studied electrochemically by linear sweep voltammetry, cyclic voltammetry and chronopotentiometry in full electrolytes. We find that the mixed potential theory is not applicable to the described system. We show that both the working potential and the rate-controlling mechanism are dependent on t...

متن کاملElectroless Nickel Plating with Hypophosphite
In the previous chapter, the components of electroless nickel plating baths were discussed from the viewpoint of the function each performs in the bath, with little attention paid to their effect on the plating process. The metal and the electron source (the reducing agent) are consumed in the electroless plating reaction and so their concentrations in the bath are continuously decreasing. Ther...
متن کاملElectroless Nickel Plating: Bath Control
In this paper, bath control is proposed for the electroless nickel plating through holes board process. The main parameters of the product (board) – thickness of the plating film and phosphorous content – are stabilized at constant levels using optimal tracking control. The set point for control is calculated from the model in dependence on the current state of the process. The pH-index and nic...
متن کاملCompetitive Spectrophotometric Study of Copper, Zinc and Cadmium With 18C6 Using TAR as a Colorimetric Complexing Agent in Methanol
A Competitive spectrophotometric method has been used for the study of complexation between Cu2+, Zn2+ and Cd2+ (M) and 18-crown-6(18C6, B) in methanol using 4-(2-thiazolylazo) resorcinol (TAR, HL) as the colorimetric complexant. Absorption spectra of the species in the M-TAR-18 C6 system at a various concentrations of 18C6 showed no formation of ternary com...
