hi,
it isnt a plating bath so dont suspect a nice and shiny nail he'
why do they call it (+)anode's in a plating bath -
-we talk about etch fluid now-
the (-) cathode get plated with the copper and the nails metal
the one who said that it speed up after pulling cu out isnt right-
ferric Chloride can etch up to a maximum of 100g of copper per liter
of solution and should be disposed.
this wholly setup is intended as trying to pull some copper out so
that it can be replace with new cu from the pcb to give it a longer
live and save some money.
thats the way i think it is, so correct me if i'm wrong :))
