Electrolytical Regeneration Processes of Common Etchants
Chemical etching has become an important part in the
production of shaped parts, printed circuit boards, and chemical
machining. A good etching agent should be inexpensive, to be
used in manifold requirements, should show a little undercutting.
and a great stability in the etching rate.
