Subject: Re: [Homebrew_PCBs] Re: Copper Clad Board

I use Edinburg etch with food grade citric acid. 10 minutes to etch a 6" x 4" board at 30'C. 6 years old and still going strong, etch time has shortened a little.

I am right
back to square on not being able to afford proxion and am
looking at carbide drill and press seen at jameco.com but
with no spec sheet. Jameco.com seems to be a good site,
company ect. My peroxide bought at dollar store is the cause
of long etch times. Has any one tried the edinbourgh etch
method? Will food grade citric acid like ones sold on
amazon.com work ok?
