All about GBO Files

The GBO file type is primarily associated with Altium Designer.

GBO	File extension: GBO
	File type:	Gerber data file

What is a GBO file

GBO files mostly belong to Altium Designer.

This file is a Gerber file that stores data for the bottom silkscreen layer of a printed circuit board (PCB). It is created during the design process with software such as Altium Designer and is also recognized by tools from EasyEDA. The file guides the machine on what text, symbols, and outlines to print on the bottom side of the board.

To use this file, a PCB designer or manufacturer loads it into a Gerber viewer or a compatible PCB design program. It works along with other Gerber files that represent copper layers, solder masks, or other mechanical elements. This integrated approach helps ensure that every layer is accurately produced during the board fabrication process.

Usage: Specifies details for the bottom silkscreen in PCB assembly.
Content: Contains printing instructions for text and graphics on the board's underside.
Viewing: Open using a Gerber viewer or PCB design software like Altium Designer.
Function: Acts as one layer among many in a multi-layer PCB design.

How can I open a GBO file?

You need a suitable software like Altium Designer to open a GBO file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your GBO file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a GBO file directly in the browser:. Just drag the file onto this browser window and drop it.

See the previous paragraphs to learn more about the main application. GBO files are often referred to as Altium Designer cads because this type of file is primarily created or used by this software.
Altium Designer
A *.GBO file represents a Gerber Bottom Silkscreen Layer data file format. It is primarily used within the Altium Designer environment for printed circuit board (PCB) design. This file stores information related to the bottom silkscreen layer of the PCB, which includes textual markings, component outlines, and other non-conductive elements printed on the bottom side of the board. The bottom silkscreen layer is crucial for assembly, testing, and identification purposes. The data within the *.GBO file is encoded using the Gerber format, a standard language for PCB manufacturing. This format precisely defines the geometrical shapes and locations of the silkscreen elements, ensuring accurate representation and fabrication of the PCB's bottom silkscreen layer. This file format is classified as CAD Files, PCB Design Files.

How to solve problems with GBO files

Associate the GBO file extension with the correct application.
Update your software that should actually open gerber data files. Because only the current version supports the latest GBO file format. Search, therefore, e.g. on the manufacturer website after an available Altium Designer update.
To make sure that your GBO file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
