Hi Todd,
IPC-2221 series documents would be a good starting point.

Subject: [TN] Gold Fingers for Edge Connectors - Design Criteria
Needed
Sent by: TechNet <[log in to unmask]>
Hi everyone,
We have a new application that will require thousands of insertions on
edge connectors such as you might find on mother board interconnects. This
is new to us so we don't have experience or design rules yet.
Are there industry guidelines/requirements for: (1) plating thickness and
performance of hard nickel and hard gold for these types of edge finger
connectors; (2) edge chamfer design; (3) finger spacing, etc.
I have seen several good supplier-specific design guidelines for edge
fingers, but no industry standards yet. I know only of MIL-G-45204 for
hard gold plating; is that useful in this application?
Thanks in advance for any insight.
Todd
