Actually Chris there was a product that provided for
a solder mask then had a conductive film ontop of that.
The manufacturers could also tie this outer skin to the
grounds on the printed circuit boord finally making the
Faraday cage !!
Papers I have read on this showed an excellent reduction
in emissions (>20dB) - neglecting the effects of the ICs
I know that AMP used to market this but it did not seem to
achieve markey acceptance.

Mat,
Can we assume you mean conductive spray coatings for plastic
caseworks? Wouldn't a conductive conformal coating would short
out all the components on the PCB? Or is a two-pass technology
with the ordinary insulating coating over the components and a
conductive layer on the outside?
Awaiting your clarification.

Subject: Conductive Conformal Coatings for reducing PCB Emissions
Hi All,
A while back there was a push to use conductive conformal
coatings for PCB emissions. Does anyone know if the
technology still exists and if so who makes it??
Thanks
