Gary,
I asked this same question 6 months ago and most people told me that it was
the additional spacing that helped, not the guard band itself.

Gary,
It is my understanding that guard bands don't work. I think your theory
that
it is the spacing that does the trick is probably correct.

Subject: [DC] Guard Banding
Good Morning
Can anyone help me with information on guard banding. I'm talking
about
shielding a trace by circling it with a ground trace. This has come
up
as a way to solve all of our EMI problems. I'm of the opinion that
the
additional spacing it requires is what helps to prevent crosstalk
and
the ground traces just take up space.
If anyone has any opinions on this (pro or con) or can point me at
some
resources on the subject I would appreciate it.
Thanks
