Hello TechNeters,



I need to know whether there's any requirement for edge connector finish. 

You know pcbs for memory module have e'lytic hard gold plating on its connector tab pads.



I could find general requirements like Ni/Au thickness, purity, hardness, etc. in IPC or ASTM stds.

But what I want is specifically related to 'abrasion resistance' property. 

Inserting into mating connector repeatedly..? What's the test method and way for pcb maker to do that?



Does anyone have idea?

Have a great day.
