Cheap Printed Circuit Board Etching Tank for use with Cupric Chloride
Was Easily assembled with a few pieces of Plexiglas and some Acrylic Solvent Cement(Methylene Chloride) Its wide enough for a fish tank heater, and a piece of fish tank hose, with holes
poked in it to agitate and oxygenate the etchant.
The boards have a hole drilled in them before etching so that a piece of string may be attached to aid in the removal of the board from etchant.
I prefer to use Cupric Chloride and have some tips Here
Etch Tank Version 2
The first tank worked well, other than a small leak, but it needed to be replaced. Another one was built, but this time some parts of it were heat bent, so it is less pieces. Along a basket type device to lower and raise the circuit boards in and out of the acid. Also made sure there was more room for the heater and bubbler.
