    Etching materials

    Has anyone used nitric acid instead of ferric chloride for etching? And if so how was his results?

    That also makes one wonder whether the other common PCB etchants (sodium or ammonium persulfates) have any use there...

    For ferric chloride or persulfates, try an electronics supply (as in where you get capacitors and wire and stuff, not a TV store!).

    Welcome. Remember that the stuff you get is high concentration. Higher than you will need to be able to control the reaction. so....gloves, shoes, apron, eye protection, and respiratory protection - all a must. This is a nasty material. Always work in a well ventilated area. NEVER pour water into acid - ALWAYS pour acid into water when attempting to water it down to your desired concentration. Keep some Soda Bicarbonate close by, so you can neutralize the acid if you need to.... And have fun :-)

    This have very little chance of having an impact but just in case... concentrated Nitric acid can potentially cause an explosion and splash upon contact with organic matter (i.e. small wood fragments) so keep that in mind. Don't ask me how I know... good thing all the safety measures were in place including a nice glass wall.

    I heard vinigar works ok. Probably not as fast. I do worry about exposure to FC over time.

    Is hydrochloric acid practical in this role?

    Looking for a signature that won't land me in trouble
