Hi Gurus,
In an imaginary case where real estate is not an issue would the gurus
prefer a fat 45 mil trace over a 18 mil or less thick 50 ohm trace assuming
current carrying ability is not an issue.
For example for a microstrip co-planar waveguide case with Fr-6 as
dielectric and half oz Cu gives 50 ohms for,
Case 1:45 mil wide trace with 50mil speration from co-planar gnds and 21
mils from a gnd plane.
Case 2:10 mil wide trace with 18mil speration from co-planar gnds and 10
mils from a gnd plane.
Which one would the gurus pick?
Thanks in advance.
