Archive of the former Yahoo!Groups mailing list: Homebrew PCBs

Oh lordy, I sure didn't want to get into chemistry when I started
tinkering with electronics, but that is just the way it goes sometimes.
I will be using up my FhCl till it's gone which may be a long time,
but, trying to figure out which to switch to is confusing me. I have
started a comparison list below and am not even sure if what I have so
far is accurate. Clarify it if I am wrong, add to it if there are
attributes I missed.
