name of : IC pin that clip on edge of a pcb ?

Check digikey p/n 15010-64000001000-ND, which includes the mounting frame so the spacing is taken care of for you.

Or use single in-line breakaway headers (and cut down to 20 pins, if necessary) like 929834-02-36-ND. Similar are available in surface mount.

You may be thinking of leadframe connectors such as

NAS interplex -

The right angle leadframe clip parts don't end up saving real estate, they just avoid the requirement for a through-hole, which is only an advantage when you're dealing with ceramic or other difficult substrates. They do allow a lower-profile straight interface, though. These pins are normally sold in reels of 10K +

There are many through-hole methods. autosplice

The Digikey mill-max parts would make more sense in low volume, but the price-per-pin will always be a signifigant factor at higher volume.

Thanks Rich.

Thanks Legg, lots of good info and yes the slip on solderable right angle pins are what i was thinking of thanks for the help robb
