"ADEKA AFES SYSTEM" is an automatic controller that regularly analyzes etching solutions and automatically feeds separately-prepared reactivating agents and water in necessary quantities based on ORP (oxidation-reduction potential), ion index (concentration of free hydrochloric acids) and specific gravity. This offers the user a number of positive outcomes including stable production of fine patterns and marked improvements in yields, etc.
