What is a .GBO file?
The file extension .GBO stands for Gerber Bottom Overlay Data File. This type of file is specifically used in the field of electronics manufacturing, particularly in the creation of Printed Circuit Boards (PCBs). PCBs are essential components used in electronic devices to connect various electronic components through a series of electrical paths.
The .GBO file is generated by computer-aided design (CAD) software tools that are used to design PCBs. Some of the popular CAD programs that can create .GBO files include Autodesk EAGLE, gEDA, and Altium Designer. These tools help designers layout the electrical connections on a PCB.
In a .GBO file, the data contained is focused on the bottom silk screen layer of the PCB. The silk screen layer in PCB design is used to add labels and other markings that help in identifying components and their placements on the board. This file is written in a format known as RS-274X, which is the most modern and widely used Gerber format. The Gerber format is a standard file format used to describe the images of a PCB including copper layers, solder mask, legend, etc.
Programs that can open .GBO files include Autodesk EAGLE, gEDA, Gerbv, Altium Designer, and Viewplot. These programs allow users to view and analyze the layout data contained in the file. It's important to note that while these programs can open and display .GBO files, the files themselves are generally used for viewing and reference purposes in the context of PCB manufacturing and are not typically edited directly.
The .GBO file can be likened to a .PDF file in terms of its use. Just as a PDF file represents a non-editable document meant for sharing and viewing, a .GBO file represents an exported, viewable version of a PCB layout that is not meant to be edited. It serves as a crucial reference for understanding and verifying the bottom overlay of the PCB design during the manufacturing process.
Originally, the Gerber format was developed by Gerber Systems but is now maintained and updated by Ucamco, ensuring it remains standard across the industry for PCB design and manufacturing.
