The nomenclature sets the stage for understanding the underlying reactions that make ferric chloride good at etching copper. In solution, ferric chloride rapidly dissociates into iron (III ...

The standard go-to solution is ferric chloride. It isn’t too tricky ... Just to remind you, copper etching isn’t just for electronics. That’ll give you something to do with your etchant ...

The copper which is not protected by an etch resist is removed by the etching process. The following are the commonly used etching methods: Ferric chloride etching solutions are widely used in the ...

Other systems include peroxide-sulfuric acid, persulfates, and ferric chloride. Process steps include resist stripping ... as well as continuous processing, constant-etch rates, and control at high ...
