At a former employer I eschewed sockets in favor of soldeing the components
(ICs) onto 15 mil thick, 4-layer test boards. The boards were 100 x 100 mm.
We then had much less to de-embed. Probing was via a 40 GHz probe.

Both Intel & AMD are no longer competing for higher CPU speeds.
Business goals are driving them towards..
lower silicon node , moderate CPU speed with multi-core architecture, much
higher functionality in smallest possible chip & High speed IO.

I want both to advance, but I actually feel it's nice to see IO make"'Si-list'"
significant advances relative to CPU speed. For many years we've had to
do cache memory and other localized speed optimizations because of the
speed costs of IO, so I'm kind of happy to see IO making some
significant advances relative to CPU throughput.

From Lee Ritchey: Isn't it amazing how quick we seem to get used to
high frequencies by saying that 6 GHz is not such a high frequency!
6 GHz? 8-) That's practically down close to DC by now, isn't it?
;-)
Lee, did you realize that it's actually been ~15 years ago now that I
working on that 13 Gbit/6.5 GHz backplane with you? That was waaaaayback
when 6 Ghz was fairly cutting edge, and we had to build that connectorparasitics & shouldgive fairly accurate results , when these IC's are
test
board to find one good backplane connector (out of 4 we tested) for
running
at that speed. It's a lot easier to do that speed now.
A lot of projects I work with these days are in the 40-75 GHz range.

There are a lot of vendors available especially for 6 Ghz which is not
such a high frequency.
looks at proceedings and exhibitors of workshops like BITS to get some
names and then contact the vendors to get the details.

Hi Group ,
We are looking for good quality IC sockets ( DC - 6 Ghz ) for the
Packages like WLCSP , BGA & QFN .These sockets should have minimal
tested .------------------------------------
Pls forward the details of any known IC socket vendors .Vendor should
provide Transmission line model of the IC sockets .
Thanks again in advance .
