V-Scoring also named as V-grooving or V-cut (or V-cutting). V-Scoring is to cut a “V” groove on the top and bottom of a bare PCB while leaving a minimum amount of material in place to hold the boards together. Rather than completing a route path around the board edge, V-scoring is a process to allow breaking boards apart after PCB assembly. This is another way to panelize the boards (see Tab Routing).
