I have put subjects in the search here and unable to locate something defined. Does anyone have a generic guideline you would follow if the customer and/or IPC doesn't state something? Couple examples is allowance of overspray on an outside of a connector body.

Doesn't get into the overspray allowance on bodies of connectors. I have submitted a request to get IPC-CC-830 and I hope that has more information.

You really need your customer to provide a drawing of coated, keep out, and don't care. People new to coating don't realise the importance of having a don't care buffer area around the keep out areas.

And conformal coating wicks up leads quite easily sometimes. That means if you are getting overspray on the outside of a connector then there is danger of it wicking up the inside. Depending on the connector of course.
