Gerber X2 Format

Metadata Structure

Attributes attached to each object in the file describe whether it is a pad or a trace. Within a gerber x2 format file, these attributes allow for automated inspection of the design against the fabrication rules. Software tools identify potential errors without manual entry of the board parameters.

Stackup Definition

File headers define the position of each layer relative to the dielectric core and the prepreg. Because the gerber x2 format includes this information in a machine readable way, the fabrication house can automate the setup of the press. This reduces the time spent on preparing the project for the production floor.

Error Mitigation

Checksums and version numbers ensure that the files used on the factory floor match the files released by the engineering team. A complete gerber x2 format release provides a single source of truth for the physical build. Proper data management prevents the production of boards with the wrong copper weight.
