The above link has been useful to me in calculating V-Scoring parameters
based upon the panel I was designing... ;-)

Charlene -
Assuming you are going to do a manual breakaway of the boards, I recommend a
final web thickness of 0.012" with 30 degree cutters on FR4. If you are
using mechanical/machine separation you can go slightly thicker. The thin
web thickness allows for easy, manual breakaway with minimal potential
damage to the components and the solder joints.
I'm sorry but I have not used RF35 so I am not familiar with its physical
characteristics. Ed/

What depth, and angle do you spec on your panel drawings for scoring a board
with a .062 thickness?
Does it make a difference on the Board Material because we are using a
combination of FR4 and RF35 for a 4 layer board.
