Revision I2 of the Gerber File Format Specification is now online

Apr 13, 2013

The Gerber file format is the bare board industry's CAD-to-CAM data transfer standard. Ucamco, its long-standing custodian and developer, has updated the file specification. By investing considerable time, money and effort in the ongoing improvement of the Gerber Format, Ucamco continues to provide the PCB industry with one of its most crucial tools, free of charge.

Ucamco is proud to present the latest Gerber File Format Specification.

After the release of  I1 it was reported that the semantics of “Exposure on/off” in macro apertures and holes in standard macro is sometimes incorrectly implemented. It is now more explicit in the specification. The errors were added to the ‘Reported Semantic Errors’ section. Readers and writers of Gerber files are urged to review their implementation in this light.
A few typo's or small errors left and right were also corrected.

As usual, if you have questions, remarks or suggestions, please post them here or mail them to Comments from the community make the specification better.
