Oxidizing agent for regenerating chlorinated Cu etching solution
● What is Oxidizing agent for regenerating chlorinated Cu etching solution?
- HB-001E is an oxidizing agent based on sodium chlorate, which is less self-oxidizing than hydrogen peroxide as a regeneration aid for quick and smooth chloride etching solution.
● Features
▶ Neutral chemical without acid or alkali
▶ Rapid regeneration of old etching solution
▶ Reduce production cost by less consumtion of hydrochloric acid
▶ High copper solubility
▶ Suitable for fast etch rate and fine pattern
▶ Maintains the best condition with Hwabaek
▶ Wide range of hydrochloric acid concentration
▶ Compatible with EF series etch factor additives
