Listening to the industrial needs and main drivers, we have developed a high quality and reliable MMO-coated titanium anode for the electrodeposition of copper, gold and other metals on printed circuit boards (PCB) in replacement of soluble anodes.
De Nora DSA® anodes for electronics succeed in tackling the undesired oxidation phenomena of organic species in electroplating baths, greatly enhanced by the catalytic activity of MMO-coated anode surfaces. Consumption of organic additives of electroplating baths such as levelers and brighteners is kept at bay by the unique formulation of De Nora DSA® anodes, preserving the fundamental role of these substances in assuring glossy metal deposits of uniform thickness.
We have also developed a proprietary design of radial cell for electrolytic copper foil production characterized by an extremely low anode-to-rotating cathode drum gap, allowing a remarkable improvement in energy efficiency and quality of the finished product. This was made possible by equipping the cells with suitably tailored De Nora DSA® anodes, taking advantage of their intrinsic flexibility and geometrical profile stability.
