Hi Everyone,

I was planning to route high speed differential traces 10Gbps over
standard FR-4 material. Can anyone suggest which FR-4 material can be
used (Nelco N4000-6 or Rogers RO4350)? Is it possible to do use standard
FR-4 without compromising signal quality.

Also is it recommended to route these traces over microstrip rather than
striplines traces? If I route it over stripline then it would require
vias to be put on every pair of these differential traces .. I am not
too comfortable doing that!!

Can anyone tell what can be done? Thanks in anticipation,

Regards,
Sunil
