For a production run of Pcbs part of the cost is material, whether it be a pcb or a pcb border, you pay for all the material used.
If you don’t need your Pcbs in a panel then keep them in singles. It will save you money.
Most assembly equipment works well with a panel approximatly 300mm x 210mm, but this varies company to company.
Common panel borders are 10mm but you don’t always need these on all four sides.
Profile cutters vary in size but the most common size to use for profiling is 2.0mm to 3.0mm.
You can therefore specify a gap between circuits of 2.0mm to 3.0mm.
Scoring a profile saves material but a score line should be approximately be 0.5mm clear of copper features.
Scoring and routing might save material but by mixing to processes, it might be more expensive.
Remember to have tooling holes and fiducial marks in the border.
For designers and engineers wishing to calculate whether they require circuits in singles or panels.
