Ucamco Releases Specification for Fabrication Documentation in Gerber
April 30, 2018 | UcamcoEstimated reading time: 1 minute
Since decades Gerber is the standard for describing the images – copper layers, solder mask, drills – in PCB fabrication data. Attributes introduced with Gerber X2 ‘add intelligence to the image’ by identifying layers, vias, SMD pad, component pin numbers and reference designator.
But PCB fabrication data is not just about images - it includes fabrication documentation such as finish, overall thickness and materials. It is essential for the quoting, planning, engineering, CAM and fabrication of the bare and assembled board. It is often transferred informally, in drawings and texts, and handled manually, wasting time and risking errors. The Gerber Job File transfers this information in a machine-readable manner as part of Gerber fabrication data.
The extension is compatible with both Gerber X1 and X2. Existing image input/output code does not need to be changed when implementing the Gerber job file.
The Gerber hallmark of simplicity and human-readability is maintained.
The Gerber Job File is straightforward to implement. Partial implementations are allowed, even encouraged. Better a partial job file than no job file at all. Developers can pick and choose from the spec what suits them. Several software suppliers have already committed to support the new Gerber Job File.
The initial draft was published on the Ucamco website for public review by the Gerber community in March 2017. There was a lively discussion, the draft went through seven public revisions before being finalized early April 2018. It became much more practical in the process.

Knocking Down the Bone Pile: Revamp Your Components with BGA Reballing
10/14/2025 | Nash Bell -- Column: Knocking Down the Bone PileBall grid array (BGA) components evolved from pin grid array (PGA) devices, carrying over many of the same electrical benefits while introducing a more compact and efficient interconnect format. Instead of discrete leads, BGAs rely on solder balls on the underside of the package to connect to the PCB. In some advanced designs, solder balls are on both the PCB and the BGA package. In stacked configurations, such as package-on-package (PoP), these solder balls also interconnect multiple packages, enabling higher functionality in a smaller footprint.
