I read in sci.electronics.design that Glenn Ashmore <gashmore@xxxxxxx> wrote (in <IwNae.33641$Zr.4112@lakeread08>) about 'PCB Etching (again!) - chemicals used', on Sun, 24 Apr 2005:
Takes about half a 1kg bottle of MG Chemicals amonium perulphate crystals to mix enough to fill the tank and it is FAR cleaner than feric chloride.
If you could please give the volume of water you use in the tank as well, we could work out the concentration, which would be valid for other tanks.
