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.
