Manufacturing data and formats

In order for the PCB manufacturer and client to immediately understand each other, we ask that you use the following data and file name links in your design work. When exporting from the CAD program, pack the necessary files (in*.zip or *.rar format) and name the set according to your own discretion – using the design name, number, etc. If you were to make changes to files already sent to Brandner PCB, please do not forget to add the version designation or number to the set name. This avoids the situation where the manufacturer might use the previous ‘incorrect’ version.
