Gold Finger Wear

Gold Finger Wear | 20 December, 2000

Question: How many insertion/removal cycles can be expected of gold finger contacts?

Problem: We manufacture a class 2 PCBA with gold finger contacts whose application will require repeated insertion and removal into card edge connectors (mother board/daughter board relationship). To confound matters, we have no control over which edge connector the board might meet.

I've contacted several connector vendors but no luck (i.e. estimate based upon plating thickness). I've been unable to locate any sort of reference. Perhaps one of you has converted a production board into test equipment and has some sort of idea or has done some sort of study. Any help would be appreciated. Thanks.
