Abstract
1,244,415. Etching. SABA SCHWARZWALDER APPARATE - BAU - ANSTALT AUGUST SCHWER SOHNE G.m.b.H. 6 Nov., 1969 [7 Nov., 1968], No. 54532/69. Heading B6J. Copper or copper alloy, e.g. copper-coated laminated materials for the production of circuit plates, are etched by immersion or spray with cupric chloride, which is regenerated with hydrochloric acid and hydrogen peroxide under the control of the redox potential of the etchant. The etchant is recirculated to sprays 4 by pumps 6, 7. The hydrochloric acid and hydrogen peroxide is supplied from tanks 8, 9 through magnetic valves 10, 11 and pumps 12, 13 controlled by an applicator 15 comprising an amplifier amplifying the potential determined by the redox electrode 14, and a measuring instrument for the potential having a pointer co-operating with two sensors to generate a signal when the potential dips to a certain point with increase in the concentration of cuprous ions, and the arrangement being such that the valve for the hydrochloric acid is opened first and closed last.
