What is Gerber X2 file format:
Gerber X2 was introduced in the fall of 2013. Gerber X2 supports attributes but is compatible with X1. Attributes are akin to labels providing information associated with the image or features in it. X2 defines a set of attributes to streamline the transfer of fabrication data from design to fabrication.
The most important new attributes in Gerber X2 are:
|
▪ |
File function: Is the file the top solder mask or the bottom copper layer, etc. |
|
▪ |
File polarity: Is the file positive or negative |
|
▪ |
Part: Does the file represent a single PCB, an array, a coupon, etc.. |
|
▪ |
Pad function: Is the flash an SMD pad, a via pad, or a fiducial, etc.. |
While Gerber X2 is an extension of the existing Gerber RS-274X , Gerber X2 provides some of the same benefits as IPC-2581, by adding the information that was missing - such as layer stack definitions, pad and via attributes, impedance controlled tracks - into original Gerbers in a backwards-compatible set of Gerber files. Netlists for testing, drills and other outputs can still be sent to manufacturers in their respective file formats. In this way, Gerber X2 provides an improved manufacturing output format that is backwards compatible with existing workflows, software, and fabrication equipment. It is therefore going to be a preferred choice for users who take a more conservative upgrade approach.
The standard file extension is *.gbr
