Titanium Anode for PCB Etching Solution
During the etching process of printed circuit board (PCB), the copper content in the etching solution gradually increases. To achieve the best etching effect, each liter of etching solution needs to contain 120 to 180 grams of copper and the corresponding amount of etching salt (NH4CI) and ammonia (NH3).

Product Introduction
Etching is an important process in the production of printed circuit boards. As the etching proceeds, the concentration of copper ions in the etching solution continues to rise. When it reaches 150g/L, the etching solution will lose its activity. The mass concentration of copper engraving mother liquor is generally about 100g/L. The two kinds of waste liquor can be recovered separately or mixed. It is a very important problem to select appropriate anode materials for electrolytic extraction of metals in sulfuric acid solution and the precipitation of oxygen on the anode.
Iridium coated Titanium Anode For PCB Etching Solution is perfect for use, which has low oxygen overpotential and is not corroded by electrolyte. Iridium oxide coating shows excellent electrolytic durability. As the waste etching solution contains a large amount of copper, it can be recycled.
Advantages of Titanium Anode For PCB Etching Solution:
Corrosion resistance, long service life, energy saving, high current density
Titanium Anode For PCB Etching Solution coated with mixed metal oxide or lead dioxide developed by Di Noer Technology Co.,Ltd. can recover copper from chloride waste liquid (acidic waste liquid), sulfate waste liquid (alkaline waste liquid) and mixed waste liquid of chloride waste liquid and sulfate waste liquid. The anode has stable operation, corrosion resistance and long service life. The anode of the product has good conductivity and effectively reduces the over potential and cell voltage.
