Hello Lou,
That's a pretty tall order. +/-10% would be achievable.
If you are using FR4, the variation in dielectric constant alone would give
you a tolerance of +/- a few percent.
regards,
Phil.

Do any one know what the type tolerance is for a controlled impedance board?
+/- 1% of a 100 ohm trace??
