Subject: [Homebrew_PCBs] a question about an etching tank!!!
hallo!
i'm making a lot of pcb's in big amounts and i want to built an
etching tank. i wanted to know what is the best way to etch a lot of
pcb's at once, and if there is a way to use less etchent for all the
pcb's. i also want to know how do i heat the etchent every time
without letting it touch heaters made of metal?
thanks a lot
mumin.
