What is a GBO file?

Data output file created by Printed Circuit Board (PCB) CAD tools such as Autodesk EAGLE and used by PCB manufacturing machines to designate layouts of electrical connections; contains layout data for bottom silk screen layers; written in RS-274X, which is the most common and contemporary Gerber format.

More Information

The GBO file acts similar to a .PDF file. It is an exported version of the PCB layout and 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.
