Oh, another way is to get a measuring reticle for a microscope to measure the score at the edges of the pcb. That way you can see if the top and bottom scores are centered over each other, the shape of the v-scores, and if they're both at equal depths.

How does the rest of the world measure scores on pcbs? We order pcbs in one of 3 different thicknesses: .031", .047" or .062" thick. We typically spec our scores to be to a .012" +/- .004" web thickness. We have had arrays come in flimsy, and even been able to see light through the scores, causing the assemblies to nearly fall apart, and other times we have received them underscored and are difficult to separate. We have no tools to measure other than verniers (and that doesnt work) How do you folks measure scores on similar pcbs? thanks, Lenny Carter.
