Revitalizing etchants
2006-03-02 by ST de Feber
Dear All, I am using Amonium Persulfaat or Natrium Persulfaat as etchant. However, it is degrading a bit. Does any one know how to revitalize it ? I know that for FerricChloride you can use HCl to do this. grtz Simon ___________________________________________________________ NEW Yahoo!
