[SI-LIST] Re: Conductor loss reduction at High Frequency

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.
