Durchlauf-Galvanikanlage

摘要

The invention concerns an electroplating plant comprising an electroplating container and a supply container between which the electrolyte circulates. In the supply container the metal content of the electrolyte is supplemented by a soluble anode which is associated with an auxiliary cathode located in an auxiliary catholyte which is separated from the electrolyte by a diaphragm which is impermeable to metallic ions. The insoluble anodes of the electroplating container are located in an auxiliary anolyte separated from the electrolyte by diaphragms which are impermeable to anions. The essential advantage of the invention is that insoluble anodes and necessary organic additives for the production of precision coatings, for example in the field of printed circuit boards, can also be used. According to a particularly advantageous development, the auxiliary catholyte and the auxiliary anolyte are guided in a common circuit such that opposed shifts in the pH value of the auxiliary catholyte and auxiliary anolyte are largely compensated as a result of their being continually mixed.
