Electrochemical solutions and water technologies for electronics - Electronics and Computers

We are committed to providing mixed metal oxide (MMO)-coated anodes and electrochemical technologies for the electronics industry. 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.
