I think your correct, but any component even passives have lower MTBF's than
just copper over FR-4 (although the Printed circuit assemblies do have MTBF
figures). Since the backplane is a huge hit time wise to repair or replace
you would like to avoid any reason to have to do that if possible.
I thought the original poster was asking about power filters
on the backplane??

February 15, 2004 regarding pentaBDE and octaBDE. Further, it indicates
that those measures shall be applied from 15 August 2004.

I read in !emc-pstc that David Heald hea...@symbol.com wrote (in

We designed the
backplane from the get-go to accept rear daughtercards for EMI filters,
I/O cables/filters, and the like. This allowed for easy

There aren't any hard document requirements that I know of but practically
this is a bad idea.
Putting components (esp EMI filters) on the backplane is generally a bad idea
for a few reasons: The first is (as pointed out by Jeff Collins) reliability
and availability. You don't want to

No, I'm not planning on shipping non-CE products to Europe, but I have
seem A LOT of products that have the CE marking that there is NO WAY
they are compliant.
I hear better things about KeyTek (Thermo)

EN 301 751 contain a list of the test to do on the equipment. For any test
there is a link to the specific equipment standards.
For example in the 38 GHz band EN 301 751 make direct references to EN 300 197
for the limits used during the test (for frequency tolerance stability point
