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

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.
The customer would prefer to not use pogo pins. Don't ask me why.

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.

Regards,
Robert
