The implicit cost of old copper anodes

The implicit cost of old copper anodes

If you are combating unevenness through electroplating, weekly anode replacement, and high additional costs. Traditional soluble copper anodes generate sludge, warp at high currents, and fail in reverse pulse lines - reducing manufacturers' scrap rates by 20-30% and extending cycle times by 30%. Baoji ShenAo Metal Materials Co., Ltd. has helped over 300 PCB manufacturers replace copper anodes with Ir Ta coated titanium anodes, reducing production costs by more than 25% within 6 months.

Why is titanium anode non-negotiable in modern PCB electroplating

How do they work

The titanium anode is an insoluble size stable anode (DSA) made of grade 1 pure titanium (99.6% Ti) and IrO coated with ₂ - Ta ₂ O ₅. Unlike dissolved copper anodes, our anode catalyzes oxygen release - without sludge, pollution, and consistent geometric shape.

5 non-negotiable selection criteria (factory validated)

Substrate: Only grade 1 titanium (1.0-2.0mm thick) has rigidity and corrosion resistance.

Coating: Ir Ta (70:30), 2-5 μ m thick, thermal decomposition porosity<1%.

Pulse compatibility: capable of handling 500-1000 A/m ² forward and 1500-3000 A/m ² reverse pulses.

Bath compatibility: g/L resistant to H ₂ SO ₄ 50-150 and 20-60 ° C.

Service life: 12-24 months, 100% recoatable substrate.

Real world performance (German automotive PCB manufacturer)

Challenge: 12:1 aspect ratio through-hole, 25% waste, weekly bath maintenance.

Solution: Our 4 μ m Ir Ta mesh anode (45% open area).

Result:

Electroplating speed+30% (5.6 μ m/min vs 8 μ m/min)

Scrap rate 25% → 3.2%

Additional cost -28%

Anode replacement from 6 months to 18 months

2-month investment return rate
