Panel Creation

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.

Panel types:

  • Multiplier: The same circuit board repeated in the panel
  • Mixed Multiplier: Different circuit boards composed into the panel

Mechanical processing

  • Scoring
  • Milling with bridges to break out (IMPORTANT: 2.0mm or 10mm spacing, see below!)
  • Milling / scoring combination

Prices for panel creation

  • Panel data provided by the customer: no extra charge
  • Panel composed by Multi-CB: surcharge starting from € 100,00 (plus VAT)
  • Milling is always free-of-charge at Multi-CB

Multiplier panel

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.

Multiplier scored

PCB panel scored

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).

Multiplier milled

When designing the panel, please observe that a spacing of 2.4mm 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.

Mixed multiplier panels

For complex panels, multiple different circuit board layouts can be composed onto one panel. The completed panel is scored, or partially milled, to provided the contained PCBs  with bridges for breaking out.

Complex PCB Panel scored

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.

Example for milling/scoring combination

PCB panel scoring and milling

When designing the panel, please observe that a spacing of 0.0mm is calculated between scored parts, and preferably 2.4mm 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!
