Abstract
SUMMARYWith a view to eliminating the use of toxic cyanide for electroplating copper, a non-cyanide alkaline bath, using triethanolamine as complexant, has been investigated. Various steps of bath developments are discussed in this paper. These include stability and immersion deposition characteristics of solutions with varying concentrations, Hull cell experiments to arrive at a plating bath composition and determination of current efficiency and deposit nature under varying operating parameters to optimise the deposition conditions.
