Abstract
PURPOSE:To obtain an etching solution of copper capable of continuous using and regeneration by providing a seed solution, wherein an oxidizing agent is added to the tetrammine copper chloride solution containing the specified quantity of ammonium salt, adjusted to an specified pH. CONSTITUTION:A seed solution, wherein more than >=one kind of nitrite or nitrate dissolve in from 0.01mol to the solubility limit as an oxidizing agent, is poured into the tetrammine copper chloride solution containing 2-5mol/l of ammonium salt, adjusted to pH7.4-11 with NH4OH in a dissolving tank 2 in an etcher 1; and a pump 4 circulates the solution through a copper ion detector 5 and sprays 6 to the dissolving tank 2. The etching solution 3 from the sprays 6 dissolves and eliminates copper from substrates of print circuit, thus heightening the copper depth value of the etching solution 3 when it is repeated. If this copper depth value exceeds the set value, the copper ion detector 5 issues a signal to the pump 4' to send a supplementary solution containing NH4Cl, NH4OH, NaClO2, NH4NO3 from a supplementary tank 8 to the dissolving tank 2 for regeneration.
