ZIF Edgecard Connector -- 12 Position

Looking for a 12-position zero-insertion-force edgecard connector. AMP has one designed for PCI cards, but it has like 48 positions or something. I'd like something smaller.

The application is a field-test fixture. Requirements for the device include: low insertion force, high reliability, modest size, and life in the thousands of cycles.

The circuit board pads are raw copper. What kind of problem does that pose? The customer would prefer to not use pogo pins. Don't ask me why.

TIA Robert

I found a 22-position by searching Digi-Key, and followed the link to the mfr:

Corrosion. I wouldn't expose bare copper to air in this kind of app at all, if I wanted it reliable at all.

Probably because they cost an arm and a leg.

But, please, at least get him to _tin_ plate the edge contacts, but really, gold over nickel is the most reliable, especially if you expect your ZIF socket (with gold plated contacts) to last for thousands of cycles.

Good Luck! Rich

Thanks for the advice. I think I'll just get that 22-position job and give it a try.
