PCB V-Scoring/V-cut
V-Scoring is used for mechanical pre-separation of circuit boards. A V-shaped breaking line is formed in
the circuit board with a precision cutting tool. Please observe the following rules:
The circuit boards spacing in the layout is 0.0mm
Scoring lines must be straight; horizontal and vertical lines are possible, and always run from circuit
board outer edge to circuit board outer edge
For stability, we recommend using scoring only above a minimum circuit board thickness of 1mm
For PCBs thinner than 1mm (down to min. 0.8mm) we offer onesided scoring
| Option | Parameter |
|---|---|
| Remaining bridge thickness | approx. 0.3mm |
| Scoring angle | 30° |
| Minimum copper / scoring line spacing | 500µm |
| Edge displacement P* | +/- 150µm |
V- Scoring Example
V-scoring is when you cut PCB marks into the laminate of the printed circuit board to make it easier to remove individual parts from the circuit board array. To V-score your boards requires a scoring tool consisting of a top and a bottom cutting blade that you run across the panel in a straight line. In some scoring machines, you pull the panel through the blades to create the scoring.
V-scoring is used consistently in printed circuit board assembly because it is a great cost saver and a highly efficient way to offer easy separation of parts from a completed assembly. Being able to offer V-scored PCBs is often considered a great value add to PCB customers.
