[Elecraft] K2 - Board Cleaning and Conformal Coating

[John Huggins, kx4o]

All,

Being in the electronics biz, we usually wash boards post assembly with
the usual products and in accordance with IPC610, etc.  Often, the boards
are sprayed with conformal coating: Some to handle "condensing
environments" and others just because someone wanted it.  My operating
locations will include salty beaches and moist mountains.

I couldn't find details in the K2 manual concerning these steps.  I did
find a few posts in old Elecraft archives, but need to ask...

Are there any components used in the K2 boards that will not tolerate
typical board washing procedures? (Most modern components expect this
step, but some don't - often switches)

Is there any reason not to conformal coat the boards once complete? (Cost
is no object to make this last a long time in beach environments)

Thanks.

John
