John / Wayne,   <--(John Wayne? ☺ )

   The connector is a through hole mount and is a custom circular aircraft type 38999 if you are familiar with that type. It has 4 mounting bosses that make contact to the board and it’s those 4 areas that we are thinking of machining down on the board. Again, the amount is only around .010” or so and as John mentioned, I was also concerned about moisture getting into the weave areas and wicking into the board. I don’t believe it would get far and the areas are free of routing and any copper features, so I’m not too overly concerned, but that’s why I’m asking the group. Maybe I’m missing something and don’t know it… ☺ The other question will be if a board shop or will it need to be a machine shop that can do the operation if we go that way. I’ll pose that to our suppliers and see what I get from them. Thanks for the replies and I look forward to more info.

Later…

If you machine into the weave you clearly have a potential for moisture ingress???



Did you consider a jig and machine the bosses?
