Eminent PCB manufacturers eliminate the problems by adopting design transfer standards that addresses all aspects of the fabrication and assembly process. Two new open standards are available, and these enable efficient and accurate data exchange from the PCB designer to the manufacturing fabricators and assemblers. In this article, the Gerber X2 is outlined for your reference.

The Gerber X2 is an expanded version of the GerberX format. In addition to the layout image data, Gerber X2 now includes design data as well. The X2 fabrication files now include the board layer order and stackup information that so far, fabricators had to interpret and verify manually. In the same way, a set of drill files is also included within the X2 fabrication files, detailing the location, drill size, plated/non-plated information, and the layer span.

The X2 attribute system qualifies objects with specifications such as file function, part, pad function, and more that add intelligence to the traditional image data improving the automation process. For instance, the file function specifies a file as top copper layer, top solder mask, while part specifies whether the PCB is a single or a panelized array, and pad function defines the pad as belonging to a via, through-hole, SMT, or fiducial. The Gerber X2 format directs all outputs to one single folder.

As the Gerber X2 is both forward and backward compatible with the RS-274X standard, it helps any X2 reader to interpret Gerber RS-274X files correctly. Therefore, fabricators using the Gerber X2 process will have no trouble interpreting legacy fabrication files created in the Gerber RS-274X format and vice versa.
