Environmentally friendly method for regeneration of copper chloride acidic solutions used in etching of printed circuits [PDF]

E3S Web of Conferences, 2017
Etching of copper with acidic CuCl2 solution is a widely used chemical method in printed circuits production. During the process, the solution is enriched in Cu(I) ions, resulting in reduction and then loss of etching bath capacity.
