Chemcut patented the etchant regeneration process nearly 50 years ago (Patent #3,526,560) and, since that time, has delivered approximately 1,000 copper and ferric chloride regeneration systems worldwide. Today, our customers can choose from three types of regeneration: chlorine, sodium chlorate, and hydrogen peroxide (copper chloride only).
Standard system regeneration capacities range from a few pounds of metal per day to over 1,000 pounds per day. Custom systems can be built to accommodate even larger capacities. All regeneration systems for copper and ferric chloride utilize oxidation-reduction and specific gravity control. Automatic control of the hydrochloric acid content is optional.
In addition to regeneration systems for copper and ferric chloride, Chemcut offers system-integrated chemistry control systems for ammonia-based etchants, micro-etch applications, developer control, and feed & bleed systems for stripping, chemical cleaning, and many other solutions.
