V-Scoring

Printed Circuit Board scoring

Scoring (also known as v-cut) 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
  • Jump scoring is possible. Please note that the roller blade of the scoring machine requires an entry and exit path. Therefore, the starting or end point of a scoring line must not be directly adjacent to the next circuit board, a distance of 15mm is necessary
  • PCBs down to a minimum thickness of 0.8mm (on request 0.5mm as special production) can be scored. Where applicable, scoring is done one-sided.
  • If you separate the panel by hand, we recommend scoring only down to a minimum PCB thickness of 1mm for handling reasons.

PCB scoring

Note: In addition to a circuit board contour within a panel, the panel contours themselves may also be scored.

Jump scoring

For example, for a more stable panel border (optional) or to make scoring possible within a mixed multiplier panel (different circuit board images).

PCB jump scoring multiplier panel

e.g. Multiplier Panel

(jump scoring optional)

  • The entry and exit path of the scoring blade is 15mm, each.
  • The circumferential panel border should therefore be min. 15mm, better 20mm.
PCB jump scoring mixed panel

e.g. Mixed Multiplier Panel

(jump scoring required)

  • The entry and exit path of the scoring blade is 15mm, each.
  • The circumferential panel border should therefore be min. 15mm, better 20mm.
  • The distance to the neighbouring PCB (in extension of the score line) should therefore be min. 15mm, better 20mm.
