What is a GTO file?

Data output file created by CAD Printed Circuit Boards (PCB) tools and used by PCB manufacturing machines; contains layout data for the top silk screen layer of the PCB; written in RS-274X, which is the most common and contemporary Gerber format.

More Information

The GTO file acts similar to a .PDF file. It is an exported version of the PCB layout used to designate layouts of electrical connections. The file is meant to be viewed and referenced but not edited.

NOTE: The Gerber format was originally developed by Gerber Systems but is now maintained by Ucamco.
