One might also check out the jewelry sellers on "etsy.com"....I purchased
some VERY
tiny brass rivets on a site (sorry, no link...Google) and they also had
eyelets.

Hypophosphites can be used in the manufacture of methamphetamine and
some
other controlled substances requiring similar reactions, so it's
hard to get
in the USA. No telling what you'll get from Asian vendors on Ebay,
or if you
risk seizure by customs. If you do order from them, you better
specify DHL
shipping or you might not have it before autumn.
If the PCBs are only 2-sided, and you're willing to drill 0.062"
holes, you
might try brass eyelets available for this purpose from Mouser. The
holes
will be 0.045" when the eyelets are in place.
Or solder copper wire in the holes... something I wouldn't want to
do if
there are many holes... but for a one of a kind home-made board
that's the
way I'd go if I could tolerate the required hole size.

Does anyone on the list have access to Calcium Hypophosphite? This
stuff is
impossible to find in the US, being a "controlled substance". For
crying
out loud. I really can't see the point considering the volumes we
are
talking about!
Alternatively, do any of you chemistry majors out there know of a
substitute
formula using more easily available chemicals?
