We must keep 300 MIL (~7.5 mm) from 1206 size or greater non-leaded parts to any scores unless we have drilled a series of small holes along the score line so they are starting and ending 400 MIL (~10.1mm) either side of the part. The holes are the same size as the top of the score. This drops to 150 MIL (~3.3mm) for non-leaded parts less than 1206 size. -- George Patrick Tektronix, Inc.

Does anybody have experience with this? Is it really necessary to keep ceramic components that far from a v-groove score? Thanks.
