There's ESD - and there's ESD. It's not always the zap that gets you.
More than a few years ago, while working at a (now gone) computer
manufacturer, I was urgently summoned to the software compatibility lab.
There I heard the EMI group accused of generating EMP and making evaluation
mother
I've heard of these polymer matrices before and wondered how
they would perform, not only for EMC, but for safety as
well. It's important to remember that using such a polymer
may have consequences in the safety arena:
* may require a connection to protective earth, if there is
a risk

GREETINGS TO ALL!
An EMC lab in San Diego County is looking for a self motivated engineer (B. S.
degree required) with at least 3 years experience to specific EMC regulations.

I'm concerned about the hazards of making proto units.
I agree with Joe and want to point out one other process for adding metal
to plastic. I believe the coating is probably cheaper than the inner metallic
housing, but I think you'll get better performance with the inner shield, in
particular if you haven't designed the plastic enclosure to work
Ken:
You might try to make the plastic housing/box itself out of a conductive
composite. We have some polymer composites which can be injection molded, and
which shield to high levels. This would get around having to redesign the
circuit and also some of the problems you cite with coatings

We apply the following standard throughout the site - development and
manufacturing - since there's always a chance that a pcb from a development
unit may end up on the shop floor by mistake. BS EN 61340-5-1:
Electrostatics - protection of electronic devices from electrostatic
phenomena.
Hi Ken:
Conductive coatings are tricky, and I generally try to avoid them. It
can be difficult to get good electrical connections at the separations
where different parts of the box meet, unless the mating surfaces have
been specifically designed for the purpose. Even so, the contact
