Homebrew PCBs

I'm in the USA in Philadelphia.  I understand the pros use spray etching.  I
think I will look at other peoples spray setups and see what they have going
on.

Yes SS is stainless.

The OP used Amonium Persulfate so SS is OK.
If you are etching other metal such as steel
or brass then you will be using FeCl3 and
stainless is not an option.

Also etching thick brass (rather than
relatively easy PCBs) then spray is the way
to go. Float etching is an option as well
apparetnly but I never had the same success
as spraying.

If you are worried about difficulty of
buidling tubes and you are down under I
can help you out. (no idea where you are
from)
