PCBs are made from Gerber 274-X data and NC drill files; Each Gerber file corresponds to one layer in the physical board – the component overlay, top signal layer, bottom signal layer, the solder masking layers inner layers and so on. Because there are so many different versions of PCB files in use today, we require our clients to provide us with a full set of Gerber and NC drill files to avoid version conflicts.
When submitting Gerber files for a quote or an order, it’s handy to have a simple text file that accompanies the data, explaining the requirements that do not appear in the Gerber files. Critical information not often easily identifiable includes solder mask and silkscreen colors, penalization requirements if any, pad finish, board thickness, and copper weight. As well as any special PCB requirements or features such as slots or cutouts. As an alternate option to a text file, these details can be placed on a mechanical layer.
A Gerber Setup dialog provides you with tools to completely configure your Gerber file output options.
