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:
