IPC-2222, 5.3.1 defines the parameters of making scoring cuts and the tolerance of the cuts, but does not specify the cuts. Our spec for 0.062" thick FR-4 boards is: 0.018-0.024"

Hi, A little off subject but I just finished a quick little experiment where I placed 0201 to 1206 and some ceramic resonators at specific distances off the scored edge. The distances from scored edge ranged from 0.025" on up at 0.025" increments.
