The modelling of a rinsing process in electroplating lines

Abstract

A method of mathematical modelling of the real distribution of contaminant concentrations in a multistage rinse system of automatic electroplating lines has been presented. In the model of rinsing, it has been assumed that mixing is not perfect. The experimentally determined coefficients of mixing are a measure of the rinsing imperfectness. The assumed method of mathematical modelling has been verified experimentally in an automatic electroplating system with a positive result. A good fit to the experimental values has been obtained. The experimental data have also been compared with the results which were obtained using a perfect mixing model.
