V-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.

V-Scoring parameters

Option	Parameter
Option	Remaining bridge thickness	Parameter	approx. 0.3mm
Option	Scoring angle	Parameter	30°
Option	Minimum copper / scoring line spacing	Parameter	500µm
Option	Edge displacement P*	Parameter	+/- 150µm

Scoring example image

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).

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.

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.
