  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.
