  Subject: [Homebrew_PCBs] Velleman PCB Etching Tank ET-20


  I've just bought one of the ET-20 Velleman etching tanks from Rapid 
  Electronics, it seemed good value at £34.95 + VAT. I've only tried it 
  with a small scrap of PCB material with a pattern scribbled on it 
  with a marker pen, but it seems to work very well, taking under 5 
  minutes to etch it using FeCl3. The tank includes an air pump and 
  heater. The bubbler is built-in to the base of the tank, and has the 
  orifices angled, so that the bubbles take a sort of circular path 
  rather than going straight up, which should help achieve even 
  etching. I managed to drop the board, clip and support wire into the 
  tank, but it was quite easy to fish it out with a long piece of 
  plastic.

  It's a lot easier than the technique I've been using for years - 
  manual agitation of a plastic food container in a larger container 
  filled with hot water.

  Here are the details:
