Paul,
Off the top of my head I can think of quite a few folks that could
accomplish this in a horizontal passive backplane/midplane that has cards
plugging into both front and back. Do you control the mechanical part of
the design? ( for insertion and extraction ) Would component side down be a
problem for cards plugged in on opposite side? Could you control the air
flow?
The usual suspects (listed in no particular order):

Schroff

Subject: [SI-LIST] : Flexible and Passive PCI Backplane?

Dear Si-List,

I'm trying to fit three or four PCI cards, one being a single-board
computer, to a passive PCI backplane that must fit into a 1 RU
(1.75" high) chassis. One suggestion is to use a flex circuit for
the
backplane and then fold it horseshoe style in order to have the
cards 'butterfly' one or two on each side.

Does anybody know of a source for such a backplane? Does
anyone have any other suggestion for getting that many PCI
cards into a 1 RU package?

Thank you in advance,

Paul Levin
