Pour-and-drain conformal coating as an alternative to potting
Is there a standard process to pour conformal coating, similar to potting, but then drain the excess? The benefit of draining the excess is to reduce weight and get better cooling.
From my limited ...

Acceptable conformal coating expansion ratio for PCB with delicate SMT parts?
I have heard that conformal coatings can put stress on SMD parts because of expansion/shrinking while curing or because of temperature differences. How much of a problem is this?
The only value ...
