Digital aperture information

The requirements of a good aperture list are that the format remains consistent and that it contains information on D-codes, shapes and sizes defined in separate fields. If complex shapes are used in the design, then a fully dimensioned drawing is required to ensure accurate reconstruction of the feature on the resulting artworks.

When standard Gerber files are supplied for design layers, it is essential that a relevant 'aperture list' accompanies the data. The aperture list should be in electronic format to ensure automatic input can be utilised (aperture lists supplied as hard copy printouts must be typed manually into the system, which can introduce human error).
