Rick,
Chomerics' Springline product line is an off-the-shelf solution:
http://www.chomerics.com/products/cardcage.htm
The spring-fingers on these one-piece gaskets are formed
toward the rear panel instead of toward the inside, where
damage due to snagging can be a problem.
The only negative comment I have about this product concerns
the stainless steel material. In my experience, mixing stainless steel
and cold-rolled steel causes corrosion, even though the CRS is Zinc-plated.
Chomerics has offered to tin-plate the SS for us.
Over the years, the design group I'm in has tried various
custom gaskets for this application--strips of tin-plated Be/Cu
or Phosphor-Bronze spring fingers between the PCI brackets
or fabric-over-foam gaskets, both of which have their
challenges. It seems we've come full-circle and have settled
on the above off-the-shelf solution.
Good Luck,
Dan

> I am fighting the age old problem of PCI brackets on various PC chassis not
making adequate electrical contact. Aperture leaks, especially at high
frequencies, is a continual problem, to say nothing about the flimsy
construction of the brackets. Has anyone had any success with the clips,
gaskets
and other EMI solutions? If you have any suggestions on types, or manufacturers
please let me know.
