In my past job we built high layer count rigid flexes for Honeywell and inserted AMP compliant pin style connectors into the rigid sections that were conformal coated previous to the insertion. It work great as long as the hole size is correct and the compliant pin is actually design to penetrate the walls in the plated holes. The reason why we did this process was for best coverage for preventing moisture and less masking.

Doug, we tried to do this when we first started down the press-fit route
but we found issues with coating (acrylic) build-up in holes preventing
proper insertion so now we insert first then coat

Subject: [TN] Conformal Coat and Compliant Pins
Good afternoon all,
Some questions came up here in a conversation this morning and I wanted
to ping the Technet group on the topic.
Do you know of papers that have been published on the topic of inserting
compliant pin / press-fit pin connectors on a conformally coated
assembly?
Do any of you do this routinely? If so, what are the benefits and
disadvantages.
Thanks in Advance.
