You want to keep it simple and dimension to a score centerline.

If you start dictating the "edge" of the score, too many variables come into 
play.  ie- score angle, score depth vs pcb thickness, and differing pcb 
thicknesses, etc..

On our arrays we always just provide dimensions to score centerline.  We 
created our array document from discussions with our pcb manufacturers, and 
now they really like our documentation!

When in doubt, call one of your pcb manufacturers and ask them.

Subject: [TN] V-Scores and board dimension


Dear Technetters,
When you specify V-Scores as a means to depanel the boards, where do you 
measure the final board dimensions from? The V-score web (score line) or the 
top edge of the Vees?

Thanks,
Amol
