I set up a folder for incoming files and it automatically resizes, renames, and converts them into the formats I need. It's like having a personal assistant!"

GBL files: Frequently Asked Questions

What are GBL files?

The GBL file format is a type of Gerber file that is primarily used in the manufacture of printed circuit boards (PCBs). Gerber files are essentially 2D image files that contain information about the different layers, traces, and components that are used to create a PCB. The GBL file format specifically refers to the file that contains information about the copper layers of a PCB.

The GBL format specifies the shape and location of the copper parts of a PCB, including the traces, pads, and vias. These files are generated by PCB layout software, and are used by manufacturers to create the copper layers of a PCB using photolithography or other methods.

GBL files are typically generated along with other Gerber files, such as GTO (silk screen), GTP (solder paste), and GTS (solder mask) files, which provide information about other aspects of the PCB design. Together, these files form a complete set of instructions for the manufacture of a PCB.
