V-Scoring also named as V-grooving or V-cutting, it is a way to split circuit boards. It is cutting a "v" groove on the top and bottom of a circuit board while leaving a minimum amount of material in place to hold the boards together.
．The spacing between boards is 0mm.
．Minimum PCB size for V-scoring is 75 x 75mm,maximum size is 450x1245mm.
．V-scoring line must be straight and have to be a vertical and horizontal line.
．The spacing between the V-scoring line and outline keeps at 0.35mm.
．We recommend board thickness of the V-scored board is 0.6mm at least.
V- Scoring Example
Kindly note V-scoring angle is 30 degrees.
