[SI-LIST] Re: strip-line impedance

As far as I know...

Assuming your planes are very wide, and the space between the planes is kept
small, there shouldn't be any significant effect to Z0 at these geometries.

A quick question:

An internal signal layer in a multi-layer stackup is situated between ground
and
a power plane. If the power plane splits into two islands is the effect
significant on the signal layer?  (Dielectric thickness between layers = 8
mil.)



Thanks.
