Titanium anodes for electroplating of PCB printed circuit boards

Titanium anodes are dimensionally stable electrodes used in printed circuit board (PCB) electroplating processes to provide a stable anode current. The substrate material is pure titanium (TA1/TA2, conforming to GB/T 3621 or ASTM B265), and the surface thermally decomposes into a mixed metal oxide (MMO) active layer, primarily composed of a composite of ruthenium oxide (RuO2), iridium oxide (IrO2), and titanium oxide (Ta2O₅).
