Product Introduction
When your etching line suffers from unstable etching rates due to anode scaling, rapid coating wear in high-chloride environments, or poor fit with custom tank designs, the Titanium Anode for Industrial Etching Machines provides a reliable upgrade. With extended acid cleaning intervals, verified chloride resistance, and support for drawing-based customization, this anode is ideal for precision industrial etching lines.

Product Features & Application
■ Acid Chloride Durability
Proprietary gradient coating technology delays erosion in high Cl⁻ electrolyte. Verified by industrial trials simulating 24-hour roll-to-roll operation.
■ Stable Current Output Without Over-Etch
Delivers uniform ion release, preventing edge over-etch and current crowding in high-speed etching tanks, ensuring consistent line widths in fine-pattern copper removal.
■ Custom Fit for Asymmetrical Tanks
Supports anode fabrication per tank layout drawings with ±0.5mm precision. Available in curved, panel, rod, or mesh format based on fluid dynamics.
■ Typical Industry Usage
Titanium Anode for Industrial Etching Machines is widely used in multilayer PCB inner-layer copper removal, FPC roll-to-roll etching, stainless steel precision pickling, and shielding foil etching lines in Tier 1 electronic facilities.
Product Details
■ Made from Grade 1 titanium with high corrosion resistance in acid chloride baths.
■ Coated via staged thermal cycle: 4-hour 400°C stress relief → stepped rise to 700°C.
■ Surface microtexture adjusted for uniform current field and anti-local hot zones.
■ Design supports edge-thickened zones for board margin etch correction (optional).
■ Each batch tested to withstand 800-cycle on/off transitions under simulated production load.

FAQ
Q1: How do I estimate the lifetime of the anode in Cl⁻ 80,000 ppm vertical etching lines?
A: At 250 A/m², expected service life is around 6,000 hours. We recommend a 0.8 safety factor in ultra-high chloride applications.
Q2: Can the anode be customized for asymmetrical twin-chamber tanks?
A: Yes. We fabricate per your tank layout or CAD sketch, including curvature, bar position, and nozzle spacing.
Q3: Is this suitable for systems with >500 ppm fluoride ions?
A: For high-fluoride content, we suggest switching to TA-F series due to increased coating risk.
Q4: Can it reduce unexpected downtime in 24h continuous etching?
A: One Tier 1 PCB supplier reported downtime dropped from 8 to 5.5 hours/month after switching to our -H model in high Cl⁻ conditions.
Q5: What certification does this product meet for temperature stability?
A: Tested to IPC-4552A standards , with surface temp variance <1.2°C during continuous flow.
