Automated System the Extreme Multidimensional Management of Process Plating

Abstract

The paper deals with the process control plating in a bath with multi-section anodes. The analysis of existing methods of process control in the bath with multi-section anodes. The influence of current density, distance between electrodes and electrolyte mixing intensity on the uniformity of coating and performance of the deposition process thickness. Established extreme nature of dependence of the uniformity of the coating on the current density, distance between electrodes and electrolyte mixing intensity. In this paper, the process of plating is considered as a object of automated control. The block diagram of a system of extreme process control plating based on the principle of management on indignation with using a mathematical model. The function chart of the extreme control system plating process in a bath of multi-anodes. In a control system there are four contours of regulation: contour of regulation of tension; contour of management of an arrangement of anode sections and intere-lectrode distance; contour of management of intensity of hashing of electrolyte and contour of maintenance of temperature of electrolyte. In feedback of all contours of regulation settle down: the block of sensors including sensors of temperature, concentration of components of electrolyte, conductivity and level; block of mathematical model of process of putting electroplated coating; block of algorithm of search of an extremum. The control algorithm of process of putting electroplated coating by means of the developed automated system of management in a bathtub with multisection anodes is developed.
