Titanium anodes are critical components in PCB (Printed Circuit Board) horizontal copper plating—an advanced process that deposits uniform, high-purity copper layers on PCB substrates (e.g., double-sided or multi-layered boards). Their unique properties address the strict requirements of horizontal plating, such as consistent current distribution, corrosion resistance, and compatibility with acidic plating baths.
In horizontal copper plating, PCBs move continuously through a horizontal plating tank, where a thin, even copper layer is electrochemically deposited on exposed copper pads, traces, or vias.
Titanium anodes act as insoluble anodes in this process (replacing traditional soluble copper anodes in some setups) or as auxiliary anodes to regulate current. Their primary role is to:Provide stable, uniform current distribution across the moving PCB surface, ensuring consistent copper thickness (critical for high-density PCBs with fine-pitch components).Resist corrosion in the acidic plating bath (typically sulfuric acid + copper sulfate, pH 0.5–2.0) and avoid contaminating the bath with anode debris.
Key Advantages Over Traditional Anodes
Compared to soluble copper anodes or other insoluble options (e.g., lead-based anodes), titanium anodes offer distinct benefits for PCB horizontal plating:
Application Scenarios
Titanium anodes are widely used in high-precision, high-volume PCB manufacturing, including:
High-Density Interconnect (HDI) PCBs: For smartphones, laptops, and wearables, where uniform copper plating on micro-vias (diameter <0.1 mm) is critical.
Automotive PCBs: For ADAS (Advanced Driver-Assistance Systems) or EV (Electric Vehicle) controllers, which require thick, durable copper layers (20–50 μm) for heat dissipation.
Multi-Layer PCBs: For industrial equipment or aerospace electronics, where horizontal plating ensures consistent copper thickness across multiple layers and blind vias.

Production
Brush coating.
Specific operation as follows:
Firstly,making the coating solution according to the type and the area of the platinum electrode; secondly ,put the solution on the surface evenly, then put them into the drying furance for drying; thirdly,we need to oxidate in the high temperature oxidation furance;Lastly, dry it to room temperature. Then,repeat these steps until you run out the configuration solution.
