Hello TechNet, I am in need of a cupric chloride solution recipe. The shop I'm now employed at (Prototron Printed Circuits, Tuscon) uses ammoniacal etchant for both inners and outers. I will be using the solution to strip/leach the electroless copper tank each week and wish to reuse the etchant until it is fully loaded with copper, approx. 25 oz/gal. Thanks in advance for any help.
