This is where the miniature eyelets come in. Usually, these are
installed using two sharp center punches. One goes on each side of the
eyelet after it's placed in the hole. A "whack" and it's seated to
stay. Next, a small amount of flux is rubbed on and the eyelet can be
soldered to both sides of the board without plugging it up. Before you
install any eyelet, check its clearance with the device pin. If it
doesn't fit now, it won't fit later either. The ones I have are very
small, accommodate IC pins and IC pin spacing. Well, .1" at least.
I can't remember where I bought these eyelets but they were expensive
and now I need some more.
