1. Agree, but that nasty end use environment is still out there and we
can't always have hermetic chassis.
2. With what?
3. Agreed, but a Vulcan mind meld might be better.

Subject: [TN] Automating Conformal Coating
Good morning all,
Another conformal coating related question. What, from an assembly point
of view, would you tell a board designer are good design practices to make
an assembly coatable from an automated standpoint.
I think we would all agree that having an assembly with no keep out zones
and a constant height for components to be the ideal. The more holes we
poke in the film and the farther we get from the ideal, the less we can
automate coating.
So, what would you tell a designer to do?
Or, to put the shoe on the other hand, what kinds of things should they
NOT do, or bad practices to avoid?
And, yes, I know It Depends.
