Surface roughness is the largest contributor we've measured for
conductor loss. There are certain low loss materials that are
constructed with high tooth copper for maximum adhesion, which show
enough loss to absolutely negate any benefit that the low loss (low tan
delta) material would have had over materials with twice the dielectric
loss.
Interesting stuff.
