The characterization of nickel deposits and quantification and optimisation
of the various additives in a Watts bath can be done successfully using th
e cyclic voltammetric stripping technique (CVS). This technique can be used
as an on-line process which can be very helpful, for industry. This powerf
ul analytical tool takes advantage of the polarisation effect. In this pape
r an attempt has been made to study the effects of saccharin, butynediol, c
oumarin on the deposit characteristics of nickel. CVS has been used to quan
tify saccharin, butynediol, coumarin content in a standard Watts bath. The
implementation of the CVS technique in areas such as PC board production ha
s increased the process yield, decrease the downtime and decreased the usag
e of excess of additive.
