Subject: [AMPS] Making PC boards/Silkscreen
Greetings Carl,
It would probably take over an hour to author a letter telling exactly how
to do the silkscreen method of making PC boards. However, if there are
enough in the group that would be interested in learning how, I could take
the time to write about it Many years ago, I did a demo for a Ham Radio Club
where I started with the tape-up layout and produced a finished etched and
cleaned ready-to-use 4" X 6" board in 16 minutes flat.
I am planning a website devoted to that task in the near furture--say by
Fall.
***I, for one, would like to see the full info.
But if you get your hands in the solution a transdermal thing will happen
and eventually you will have Amonium Chloride (from the Amonium Hydroxide
reacted with Hydrochloric Acid) get into your urine and you'll flunk a U/A
for methamphetamine.
*** I imagine the other reason for failing the test is more fun. One place I
worked years ago had a home brew gold plating unit. There were ampules of
amyl nitrate with built in 'snorting tubes' in case of cyanide problems. It
always surprised me that they were still there.
Steve
