If you export the Gerber poduction data by yourself, please refer to the following instructions.
Basically, you send us Extended Gerber (RS-274X) or Gerber X2 data and in addition the drilling program (Excellon or Sieb & Meier). If your software allows it, we recommend instead of Gerber the export of ODB ++ data!
The Gerber format (originally from 1980) enables data exchange between CAD (development) and CAM (production) and is used primarily to output the layout data used for printed circuit boards. The advanced format Extended Gerber (RS-274X), developed In 1998 by the company Barco ETS, is today's standard in the PCB production and is now cared for by the company Ucamco NV.
The latest acknowledged format Gerber X2 is now also used in production.
All popular CAD programs allow exporting the design in the Extended Gerber format, and all popular CAM programs of printed circuit board manufacturers are capable of importing it.
Please do not use the outdated standard Gerber (RS-274D) for export.
