We just got back a few boards from APCircuits (great job, BTW) for prototyping a circuit....2-sided, no solder masks or silkscreen.
Some traces are separated by only 10 mils and it just occurred to us
that condensation might be a problem (shorting out traces) without the
solder mask. The product that these proto boards are part of could
easily be brought inside from below-freezing temperatures and used immediately.
Has anyone heard if this can be a problem? If so, is there a
recommended spray that we can use after assembly to protect against
this? I suspect clear Krylon might not be the best
solution...something removable would be great. :-)
