- Аннотация: Cyclic voltammetic method with stripping (CVS) is used to determine the concentration oforganic additives of various natures in electrolytes for metal coatings used for the manufacture of printed circuit boards (PCB). It is based on the quantitative determination of the inhibiting or activating effect of the additive depending on the concentration in the bath. Since the rate of metal deposition in the CVS cathodic cycle depends on the content of the additive in the electrolyte, the charge spent on stripping metal in the anodic cycle is proportional to the additive concentration and can be used as an analytical signal. To increase the stability of the results,measurements are carried out in a special cell with a rotating micro disk electrode, ensuring the constancy of hydrodynamic conditions at the electrode. The previously patented “Korian” method developed on basis CVS is adapted to the IPC brand potentiostats by means of a specialized application for a personal computer in addition to the standard program of the serial IPC device. This program allows you to fully automate the analysis of additives by controlling the operating modes of the potentiostat and processing the results obtained. The analysis results are presented in digital form and graphically. The principles of realization of the analysis of the various nature organic additives in various electrolytes (not only PCB) by the CVS method “Korian” are discussed. Specific examples show the possibilities of quantitative determination of the concentration of organic additives in industrial baths, their efficiency, consumption and stability during storage and electrolytic deposition of metal coatings. This method and the “Korian” hardware and software complex is used at many plants in Russia and abroad.
