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.
