For cost-saving or technical reasons (such as improved assembly), multiple circuit boards may be combined to form one large board, a “panel”. This panel is then produced just as a single large circuit board. A separation of the panel does not occur!
Always consult with your assembly partner about the panel design; take note of (for example) fiducial marks and capture holes! A damaged circuit board (according to E-test) will not be removed from the panel, but rather marked. This must be observed during assembly.

Multiple identical circuit board layouts are composed to form one panel. The completed panel is scored, or partially milled-out to provided the contained PCBs with bridges for breaking out.
When designing the panel, please observe that a spacing of 0.0mm is left between the circuit boards.
The contour line thickness should be 0.01mm / 1 mil.
Because of the tolerances when breaking out the single circuit boards, all conductor traces and copper areas should have a spacing of at least 500µm from the scoring edge (see scoring).
We recommend using scoring technology only for panels with a circuit board thickness of at least 1mm (stability).
When designing the panel, please observe that a spacing of 2.0mm is left between the circuit boards.
All conductor traces and copper areas should have a spacing of at least 200µm from the milling edge.
If no bridges are defined by the customer, these will be inserted by Multi CB! Optimum width for the bridges: 1 to 1.5mm.
When designing the panel, please observe that a spacing of 0.0mm is left between the circuit boards.
The contour line thickness should be 0.01mm / 1 mil.
Because of the tolerances when breaking out the individual circuit boards, all conductor traces and copper areas should have a spacing of at least 500µm from the scoring edge (see scoring).
We recommend using scoring technology only for panels with a circuit board thickness of at least 1mm (stability).
When designing the panel, please observe that a spacing of 10mm (394 mil) is left between the circuit boards.
All conductor traces and copper areas should have a spacing of at least 200µm from the milling edge.
If no bridges are defined by the customer, these will be inserted by Multi CB Optimum width for the bridges: 1 to 1.5mm.
When designing the panel, please observe that a spacing of 0.0mm is calculated between scored parts, and preferably 2.0mm between milled parts.
All conductor traces and copper areas should have a spacing of at least 500µm from the scoring edge, and at least 200µm from the milling edge!
