Hi guys:
What's the best way to separate PC boards that loses the least amount of material? Currently, when I have several small circuits on a single PCB that need to be cut apart, I use a band saw. But this method is crude, comes too close to the traces, and I end up wasting a lot of material.
Is there a better way? How do the board manufacturers cut their boards?
Thanks for any replies.

You can have them scored so they 'break apart'.

I score both sides with a scoring knife and break them, then sand the edges with silicon carbide paper.
They route the outline, either all the way through with a cylindrical cutter, or V grove each side with a pointed bit, for later break separation.
