Dear X,
What sizes?  How many do you need?  If you're looking for a small quantity of cut pins, forget it.  Go to smallparts.com order SS precision machined stock (it's cheaper that music wire, go figure).  Use a diamond cutoff wheel to cut them and then debur.  Tumble debur does not work well with the cut ss.  We use SiC grind.
The IPC A/B-R Standard is 2mm drill, 0.078" pin stock.  This yields a slip fit that works for your smallest laser blinds.

Oh ya, Louis and Tom - I never replied about the brilliance of the A/B-R.  I was hoping that you would just catch the infomercial.  It's on at 2am (Spike channel, of course).  Or you can come to the 1-10C meeting. Keep in mind that according to our chairman, the design is finalized until 2221 Appendix A amendment 1 (by my calculations, 2015).

Fellow TechNetters:

   I am searching for an assortment of the above stated pins, not in large quantities at this time.   We are conducting Thermal Stress on Plated Through Hole without an expensive tooling machine.   I am currently working with 0.019 thru 0.042 thousand finish hole sizes.   I need to pin several coupons on one mount.   I don't need precisions pin as they are discarded after use.

Any ideas, comments/suggestions.

 Victor,
