Gerber file – data files critical to PCB manufacturing


Gerber file is a data file format developed by Gerber Technology, Inc., for use in the process of creating and manufacturing printed circuit boards (PCB). The Gerber file format is used to store information needed by PCB designers which allows them to create schematics and manufacturing files that can be used by PCB manufacturers.

What is a Gerber file?

Gerber files are used to organize and manage the manufacturing of electronic devices. They are also used as a tool for assembly and troubleshooting. Gerber files contain information about each component and its relationships with other components or assemblies. Gerber files can be used to help with the design, assembly, testing, and troubleshooting of electronic devices.

They are a way to store data in the form of a printable file that can be sent to a printer or scanned and used for other purposes. They are created using specialized software and commonly include information about the part including type, size, material, chemical composition, and other details.

What are the different versions of Gerber File?

Gerber files are used in all areas of electronics manufacturing, including semiconductor fabrication facilities, foundries, and assembly plants. They are also used in other industries where electronic components must be assembled on substrates that adhere to strict standards. There are two types of Gerber files.

Extended Gerber or RS-274X

The first is the Extended Gerber or RS-274X. This is a version that contains additional information regarding what’s being printed, such as the dimensions of the print and other information like that. It also includes additional data in case the printout needs to be scanned and sent to another machine for further processing. It contains an Electronic Data Interchange (EDI) specification that defines the data structure and media characteristics of the file.

Standard Gerber or RS-274-D

The second type of Gerber file is the Standard Gerber or RS-274-D. This format was originally developed for use with older printers and scanners but can still be used today if your printer supports it by installing a driver from your printer manufacturer’s website. It can also be used to capture 3D models of parts and assemblies in 3D CAD programs.

What is the purpose of Gerber files?

What-is-the-purpose-of-Gerber-files● Gerber files are an essential part of the manufacturing process for many companies.
● A Gerber file is a file that contains detailed information about the object you’re designing. This could be a circuit board, a piece of software, or even something as simple as a t-shirt.
● The purpose of a Gerber file is to give manufacturers and other people who work with electronics an easy way to communicate with each other.
● Gerber files are made up of lines and curves that represent geometric shapes called vectors.
● Gerber files are a type of file used by engineers and designers to store design information.

How do I make a Gerber file?

To make a Gerber file, you can either use an existing Gerber file or make one from scratch. If you have an existing Gerber file, you can open it in the Gerber Editor and then use the Save As function to save your own version of it. You’ll be able to do this for any type of Gerber file (e.g GDS, OBJ) that supports files saved through the Gerber Editor.

If you want to make your own version of an existing Gerber file, then open up your CAD software (like Autodesk Inventor). From there, create a new part by selecting Create > Part > New Part File from the menu bar at the top of the screen. Use this new part as a template for creating your own files using an appropriate format such as.DXF or . DWG.

What software creates Gerber files?

1. Altium
Altium is a CAD package that offers a wide range of tools for creating PCBs, printed circuit boards, and other electronic components. It is used by professionals and hobbyists alike.
2. Eagle
Eagle is another popular PCB design software, which is free to download and use for Windows, Mac OS X, and Linux operating systems. It comes with plenty of tools that allow users to create schematics and layouts for their projects.
3. Cadence
Cadence Design Systems (formerly Cadence) is an American company headquartered in San Jose, California that specializes in digital design software products for electronic system designers and semiconductor foundries.

How-do-I-convert-Gerber-files-to-PCBHow do I convert Gerber files to PCB?

You can use Gerber files to create a PCB by using Eagle. Eagle is a free, open-source CAD program that can be used to design PCBs. It has a lot of features and is easy to use.

PCB factory can directly produce the final PCB through Gerber. At present, the commonly used format is RS-274X, and most board manufacturers also support the latest Gerber X2 format.Here, we will explain how to convert Gerber file to PCB through the tool”Camtastic” included in Altium Designer software.

Step 1: Create a new Cam document
● File-New-CAM Document

Step 2: Import Gerber and NC Drill
● File-Import-Gerber, and then import the gerber file into the cam file created in step 1;
File-Import-Drill, and then import the drilling file into the cam file created in step 1;

Step 3: Check the mapping relationship of layers
● Click Tables » Layers to open the mapping interface, and check whether the relationship between the corresponding pcb layers after gerber import is correct through the Gerber file suffix generated by AD in the above table and its representative meaning.

Step 4: Adjust the layer order
● After checking the layer mapping, you need to adjust the physical order of the signal layer, click the Layer » Order menu to access.

Step 5: Extract Net
● If there is no problem in the above steps, you can reverse the netlist information in the PCB through Gerber and NC Drill. Click Tools » Netlist » Extract menu to get the net list of PCB.

Step 6: Export PCB
● The last step is to export PCB. If the Net List or other information is missing, the Export to PCB menu is gray and cannot be clicked.

Step 7: Check and optimize the exported PCB file

What program opens Gerber files?

There are several programs that can open Gerber files:

AutoCAD is a CAD program used in the design and drafting of products and structures. It’s also used for technical drawings and large-scale presentations.

Inventor is a 3D CAD program used to design prototypes, maintenance drawings, and production parts.
SolidWorks is a SOLIDWORKS CAD software package that provides an integrated solution for the design, simulation, and manufacturing of parts in manufacturing environments.

How do I view Gerber files in cadence?

You can view Gerber files in cadence with the following steps:
1. Open a Gerber file in cadence.
2. From the File menu, select Open and navigate to the .dxf file you want to import.
3. Double-click on the .dxf file to open it in cadence.

What is the extension of a Gerber file?

The extension of a Gerber file is .GBR. A Gerber file is a file that contains information about how an electronic component should be manufactured. It has both the parts list and the manufacturing instructions. A Gerber file is used to manufacture electronic components such as resistors, inductors, capacitors and other semiconductors.

FAQ bout Gerber file


Why is it called a Gerber file?

The name comes from the Gerber code, which is used to describe a PCB layout. The code is also used in electronics and manufacturing and has been adopted by many other industries for their own purposes.

Can AutoCAD open Gerber files?

Yes, AutoCAD can open Gerber files. In fact, it’s one of the best tools for creating PCB designs in CAD software like AutoCAD or Inkscape.

Can Gerber files be edited?

Yes, you can edit a Gerber file with any text editor such as Notepad or WordPad on your computer system as long as it supports Unicode characters (UTF-16).


Gerber files are files that can be generated by all circuit design software. They are also called stencil data in the electronics assembly industry and photo files in the PCB manufacturing industry. It can be said that Gerber file is the most common and extensive file format in the electronic assembly industry. Therefore, for an electronic production enterprise, it is very important to have a CAM software that can handle Gerber files. It can help to improve the quality of each process of product preparation, manufacturing and testing.
