So we ask him again: What values did you enter, and what dielectric constant

You are getting to be a real pain in the keyster... LOL

I use 0.062" 1oz FR4 for my designs.
The dielectric constant of FR4 is about 4.6
Thickness of 1oz copper is about 0.0014"

So with a ground plane on one side of the board... the width of the
trace to maintain a 50 Ohm characteristic impedance is about 0.113"
wide.

P.S. Have no idea what tape you're talking about...
