GTL files: Frequently Asked Questions

What are GTL files?

The GTL file format typically refers to Gerber files, which are used in printed circuit board (PCB) manufacturing. Gerber files contain the manufacturing data for PCBs, including the exact location and shape of conductive traces, holes for components, and other design elements. They are used to communicate the PCB design from the design software to the manufacturer, who will use the files to create the PCB. The .gtl extension is sometimes used instead of the more common .gbr extension for Gerber files, but the file format is the same.
