What I'm looking for are small copper tubes which are intended to be 
used for PCB vias instead of electroplating through holes.  I've used 
them before and think they're great but cannot remember the name of 
the company who sells them.
Ande:  International Eyelets.  Sorry, I have NO clue of their address, etc., 
but a simple Google search should getcha whatcha want.  I have used a few of 
theirs, gold-plated phosphor bronze, and some with tin plating, but the latter 
have to be quite fresh to solder well.  TINY, delicate.  I use an awl to 
spread the inserted end, once "home".  By hand.  No drill-press necessary.

These should ALWAYS be soldered!  I prefer to at least TIN the pad before 
inserting the eylets, to make sure "SOME solder got UNDER there".

There are flat, belled, and horn-shaped "heads" available, at least for SOME 
manufacturer of these.  One might beg a tiny bag of samples to make up his 
mind.  

Lossa luck!  Jan Rowland
