Not by design Doug. If you have exposed planes then there may be
justification, but since coating only really prevents leakage due to
condensation, the fact that it isn't there makes no difference as far as
I can see

Subject: [TN] Conformal Coating Board Edges

Good afternoon all,

I am glad we all appreciate Inge and the time he puts into making this a
fun and interesting forum.  To sum up: Ditto.

I have a question related to conformal coating, a sort of survey.  For
those of you that conformally coat your assemblies, do you coat the
edges of the boards?  Why or why not?

There is an internal debate here and I wanted some other viewpoints
before offering my own.
