Russel,
?? Do you use your etchant around tools like in a shop environment? I know the HCI is the troublemaker but how does the polystyrene help? I have somewhat of a machine shop so lots of steel and tooling etc to worry about.
It sits in the corner of a normal room, about 1.2m from a small pcb drill press, and rust isn't higher than that from a normal room environment.
I'm only using the polystyrene slab because it's a convenient size and doesn't fall apart or absorb much.
You'd need some more weight on it to make sure the seal is good.
I only make 6-8 runs of PCBs a year.
Corrosion obviously happens some amount when the etcher is running, so having it on a separate table would be good if lots of shiny metal parts are nearby.
Russel,
? Ok, good info. So if I do my etching under my 24x24x14 carport outside, I should be good and the carport should escape rusting too. I think I can rest easy on the rust thing now as I have enough info on how not to be careless. I have to also realize I am a noob and have to design stuff to etch. Or download other peoples stuff to etch I probably won't be etching all of the time to worry about it.
Thanks
