Generating Output Files for Copper Layers
When generating output data files use “flashes” for pads and avoid “painted/drawn” pads.
For larger copper areas or copper planes avoid filling them with small draws (“painting”).
Where possible, use contours or polygons to construct areas or planes, these are standard features in Gerber X2 output as well as other data formats.
Always include the board outline when you output your copper layers as this helps us to identify any data alignment, rotation or mirroring issues.
This is best done using a small line – e.g. 0.50mm (20mil) wide – where the centre of the line is the exact board outline.
We will remove this line from the production data we produce for the manufacturing process.
