Titanium anodes play a crucial role in the PCB (Printed Circuit Board) manufacturing process, primarily due to their excellent corrosion resistance, stable electrochemical performance, and long service life.
Types of Titanium Anodes Used in PCB Applications
Advantages of Titanium Anodes in PCB Manufacturing
Corrosion Resistance: Withstands acidic/alkaline electroplating baths (e.g., copper sulfate, nickel chloride) without dissolution, preventing contamination of the solution and ensuring coating purity.
Stable Electrochemical Performance: Maintains consistent potential, reducing hydrogen evolution or side reactions, and enabling uniform metal deposition (critical for thin-film circuits and fine-pitch vias).
Long Service Life: Compared to soluble metal anodes (e.g., copper or lead), titanium anodes require less frequent replacement, reducing production downtime and maintenance costs.
Environmental Friendliness: Minimizes anode material loss into the bath, facilitating solution recycling and reducing heavy metal emissions in wastewater.
Applications of Titanium Anodes in PCB Manufacturing
1.Electroplating Processes for Circuit Formation
Copper Plating (Through-Hole Plating and Surface Plating)
As insoluble anodes in copper electroplating baths (e.g., acidic copper sulfate baths), titanium anodes coated with metal oxides (such as MMO, Metal MMOx Anode) provide a stable oxidation environment. They facilitate the dissolution of copper from the soluble anode (or maintain copper ion concentration via external supply) and ensure uniform copper deposition on PCB vias and surfaces, critical for forming conductive circuits.
Tin/Nickel Plating for Surface Finishing
In tin plating (for solderability) or nickel plating (for corrosion resistance), titanium anodes (often with Ru-Ir or Ir-Ta oxide coatings) maintain stable potential, promoting consistent metal ion release and uniform coating thickness on PCB pads.
2.Electroless Plating and Etching Auxiliary Processes
Anodic Oxidation in Etching Solutions
During PCB pattern etching (e.g., using ferric chloride or acidic solutions), titanium anodes can be used to assist in electrochemical etching, accelerating the removal of unnecessary copper layers while minimizing damage to the target circuit.
Anode Protection in Electroless Plating
In electroless copper or nickel plating, titanium anodes may serve as auxiliary electrodes to regulate solution potential, preventing side reactions and improving plating uniformity.
3.Wastewater Treatment in PCB Production
Electrochemical Oxidation of Toxic Wastewater
PCB manufacturing generates wastewater containing heavy metals (e.g., copper, nickel) and organic pollutants. Titanium anodes (e.g., PbO₂/Ti or MMO anodes) are used in electrochemical treatment systems to oxidize organic contaminants and precipitate heavy metals, enabling wastewater recycling or compliant discharge.

Production
1. Substrate treatment: it needs to be treated by roughing, cleaning and removing oil, which can increase the compactness of catalytic.
2. Brushing coating:After substrate treatment, it will be proceeded brush coated. The main coated content is platinum group metal, which is a kind of mixed solution.Then, heat treatment will be going on after drying.The whole procedure need to be repeated many times. This method is better to form thin oxide catalytic that is lamellar adhere to substrate surface.
