["Bergey, Dana" <DBergey@xxxxxxxxxxxxxx>]

Dr. Johnson,

FCI has several years of experience in the area of surface mount backplane
connectors, and we believe it will be an important technology in the future
as our customers implement ever faster serial data rates. One of my
colleagues will be sending you a position paper before the end of this week
for your information, and we will be pleased to discuss it further after
your review.

At DesignCon2002, we conducted a TecForum, which included a section on the
advantages of BGA backplane connectors.  You can review the slides from that
TecForum at

http://www.fciconnect.com/pdffiles/highspeed/FCI_DesignCon_2002.pdf

I look forward to your column, and hope we can contribute in some way.

Regards,
Dana

Subject: [SI-LIST] backplane connector



I'm doing some research for an EDN column about the use of
surface-mounted backplane
connectors as opposed to press-fit types for high-speed
serial backplanes (in the
GHz+ speed range).

Of course the press-fit conectors have the advantage of not
requiring soldering on
your backplane, which means you can incorporate cheezy
plastic parts into the connector
shells.

The surface-mounted connectors work well with very small
blind
vias which are good for high-speed signals.

Which is best? Where are we going in the future?

Any comments you would care to submit to my attention (
howiej@xxxxxxxxxx ) or post
here on the si-list would be greatly appreciated. Please
include the words:
"backplane connector" in the subject line to make sure I see
the message.
