Platinode® platinized titanium anodes are used for precious metal plating and non-ferrous base metal plating.
Mixed Metal Oxide Anodes / MMO Anode
Metal oxide anodes are manufactured from precious iridium and ruthenium oxides, sometimes combined with non-precious tantalum and titanium oxides. Solutions of these metals are applied in layers in a multi-stage process; they are transformed in a thermal process into their catalytically effective shape.
Low oxygen-generating anodes reduce process variability and increase productivity.
Uyemura 187 SO MMO anodes markedly reduce the over-potential for anodic oxygen evolution. Additionally, the excellent stability of the MMO coated titanium anode does not contaminate the electrolysis system, improving the product’s purity and minimizing maintenance costs.
For acid copper PCB applications, 187 SO MMO insoluble anodes from Uyemura improve copper plating distribution, and eliminate nodules. The anode offers a constant area and does not require an anodic film.
The 187 SO anode enhances productivity by eliminating the costly downtime for anode maintenance and dummy plating.
