Hi,
With a new kitchen soon to be delivered I have been told, in no uncertain terms, that etching pcbs in there will not longer be tolerated - or risk untold personal damages !
So I'm going to knock together a vertical style etching tank from an old fish tank, heater and air pump.
Wondered if the Ferric Chloride solution I use needs to be drained off and stored in a sealed container every time I use it - not sure if it oxydizes quickly ?
Thought putting a cover on the top of the tank might suffice ?
Also wondered how much the bubble size from the air pump matters - can I just let it bubble from the airline tube or does it need an airstone, fine or course - although concerned they might fall to pieces in the etchant ?
thanks
