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

[robb]

it is a connector device that you clip/solder on the edge of a
pcb that looks like an IC pin when your are done... but it is on
the edge of a PCB

what i am trying to do is create another PCB DIP 40 adapter for
a smaller SMT/SMD chip package. the PCB will have traces on one
side for the SMD chip where pin traces lead to the pads along the
edge of PCB to accomodate these pin connectors.
The PCB part will be cut to the size of a DIP 40 device
(obviously. ? ) so with ??pins installed?? look like a
Franken-DIP-40 with a SMD chip piggy back

the **space is very tight ** and i also want sturdy pin
connectors. I have seen these used somewhere but can not figure
where so as to show an example

thanks for any help,
robb

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

http://www.interplex.com/nas/catalo...?OpenView&RestrictToCategory=Dual Inline Pins

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.

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