EFA CAMverse › Gerber viewer
New Gerber X/X2 + coordinates become Gerber X3 (for assembly) → Format guide · GerberA folder full of .gbr files and drill data? EFA CAMverse opens the complete Gerber set (RS-274X, X2, X3 plus Excellon) natively – no cloud upload – and shows layers, stackup, drills and 3D. And if the component data is missing, you add it from a coordinate file.
Gerber – the de-facto manufacturing standard: one image per layer, drill data as Excellon.
Gerber is by far the most widely used exchange format in PCB fabrication. Each file describes one layer (copper, solder mask, silkscreen …) as 2D vector graphics; a typical data set consists of several Gerber files plus separate Excellon drill data. Practically every EDA tool can export Gerber, and every fabricator worldwide can read it.
The format goes back to Gerber Scientific and is maintained by Ucamco today. The base standard RS-274X (“Extended Gerber”) was extended by Gerber X2 with attributes (layer role, polarity, pad function) and by Gerber X3 with component data for assembly – classic Gerber without these attributes remains a pure image format with no nets and no components.
Download for free and install – a native Windows application (10/11, 64-bit), free to use as a viewer.
Open the layer files – EFA CAMverse assigns the layers by itself. Excellon drill data is read along, and an accompanying job file (.gbrjob) is evaluated for layer roles and stackup.
Toggle and mirror layers individually, read drill tables, measure distances – and switch to the 3D view with one click.
Everyday EMS reality: the customer delivers classic Gerber data without component information – plus some pick & place file. EFA CAMverse merges both and adds the complete component layer you otherwise only get from Gerber X3.
Gerber X3 (for assembly)
Toggle every layer, control transparency, mirror per layer if needed – if a .gbrjob is present, EFA CAMverse reads layer roles and stackup from it.
Excellon and Excellon 2 drill data is read along – drill tables show tools and diameters.
Layer roles, pad functions and – with X3 – component data are taken from the attributes.
With Gerber X3 or an added coordinate file: components with reference, value and package – from X3 also MPN and manufacturer; for bill of materials, quotation and assembly print.

Output or print the view as PDF, PNG or JPG – for documentation and coordination.
A native Windows application – no cloud, no upload. Your manufacturing data stays on your machine.
EFA CAMverse passes the Gerber set on directly – as DXF or as GenCAD, without going through another program.
Depaneling · design · documentation
Outline, milling channels, tabs and drill holes for your depaneling software, component outlines and fiducials for your CAD program, all layers as a drawing.
With Gerber: outline and milling paths from the Gerber layers, drill holes from the Excellon data – separated into plated and non-plated.

The basis for programming your test and production equipment – optionally with only the components of the customer variant.
With Gerber: the components come from Gerber X3 or from an added coordinate file – layers, pads and drill holes even without.
More about GenCAD export →Classic Gerber data (X/X2) contains no components. Add the coordinate data in EFA CAMverse – this creates a quasi Gerber X3, from which EFA SmartSuite generates a fully set-up EFA project.
Prerequisite with Gerber X/X2: only with component data can EFA SmartSuite play to its strengths. If you already have Gerber X3, the first step is not needed. How to extend Gerber to X3 →

Which Gerber version do I have?
Gerber vs. ODB++ & IPC-2581Classic Gerber is a pure image format: it knows vectors, but no nets, components or layer roles – drills live separately as Excellon. The “intelligent” formats ODB++ and IPC-2581 bundle the complete product model instead. X2/X3 partially close the gap with embedded attributes. EFA CAMverse reads all 3 worlds – in the same tool. To the ODB++ guide →
And when the next customer delivers something else: EFA CAMverse also opens 8 more PCB/CAM formats – in the same tool, with the same way of working.
