Introduction to Gerber X2

Gerber X2 is a modern file format used in the electronics manufacturing industry for the exchange of PCB design data. It is an extension of the widely used Gerber RS-274X format, offering enhanced features and capabilities that streamline the PCB Fabrication process. In this article, we will explore the various reasons why you should consider supplying us with Gerber X2 files for your PCB projects.

What is Gerber X2?

Gerber X2 is a file format developed by Ucamco, the company behind the original Gerber format. It builds upon the foundation of the RS-274X format, adding new features and enhancements to improve the efficiency and accuracy of PCB fabrication. Some of the key features of Gerber X2 include:

• Embedded aperture definitions
• Attribute metadata
• Improved layer structure
• Standardized file extensions

These features provide a more comprehensive and unambiguous representation of the PCB design data, reducing the chances of errors and misinterpretations during the manufacturing process.

Benefits of Using Gerber X2

1. Enhanced Design Clarity

One of the primary advantages of using Gerber X2 files is the enhanced clarity and completeness of the design data. With Gerber X2, all the necessary information required for PCB fabrication is embedded within the files themselves. This includes aperture definitions, layer stackup information, and other crucial metadata.

By providing a self-contained package of design data, Gerber X2 eliminates the need for separate aperture lists or drill files. This reduces the chances of missing or mismatched information, ensuring that the PCB fabricator has a clear and accurate representation of your design intent.

2. Improved Communication and Collaboration

Gerber X2 files facilitate better communication and collaboration between PCB designers and fabricators. The format supports the inclusion of attribute metadata, which allows designers to convey additional information about the design, such as:

• Layer types and purposes
• Material specifications
• Impedance requirements
• Finish options

This metadata can be easily accessed and interpreted by the fabricator, reducing the need for back-and-forth communication and clarifications. With Gerber X2, you can be confident that your design intent is clearly communicated, minimizing the risk of misunderstandings and delays in the manufacturing process.

3. Streamlined Data Transfer and Handling

Gerber X2 streamlines the data transfer and handling process by providing a standardized and organized file structure. The format defines specific file extensions for each layer type, making it easy to identify and manage the various aspects of the PCB design.

For example, Gerber X2 uses the following file extensions:

Layer Type	File Extension
Top Copper	.gtl
Bottom Copper	.gbl
Top Solder Mask	.gts
Bottom Solder Mask	.gbs
Top Silkscreen	.gto
Bottom Silkscreen	.gbo
Drill Data	.drl

This standardized naming convention ensures that all the necessary files are easily identifiable and organized, reducing the chances of errors or omissions during data transfer and handling.

4. Improved Manufacturing Efficiency

By providing a comprehensive and unambiguous representation of the PCB design, Gerber X2 files enable faster and more efficient manufacturing processes. The enhanced clarity and completeness of the design data reduce the need for manual intervention or interpretation by the fabricator.

With Gerber X2, the fabricator can quickly and accurately set up their manufacturing systems, minimizing the chances of delays or errors. This translates to faster turnaround times and higher quality PCBs for your projects.

5. Compatibility with Modern PCB design tools

Gerber X2 is widely supported by modern PCB design tools and CAD systems. Most popular PCB design software packages, such as Altium Designer, KiCad, and Eagle, have built-in support for generating Gerber X2 files.

This compatibility ensures that you can easily create and export Gerber X2 files from your preferred design environment, without the need for additional tools or conversions. By using a widely supported format like Gerber X2, you can seamlessly integrate your design workflow with the fabrication process.

FAQ

1. Is Gerber X2 compatible with older PCB fabrication equipment?

Yes, Gerber X2 files are backwards compatible with older PCB fabrication equipment that supports the RS-274X format. The additional features and metadata in Gerber X2 are optional and can be safely ignored by older systems, ensuring a smooth transition to the newer format.

2. Are there any size limitations for Gerber X2 files?

No, there are no inherent size limitations for Gerber X2 files. The format is designed to handle PCB designs of various sizes and complexities, from small simple boards to large and intricate designs.

3. Can I include custom attributes in Gerber X2 files?

Yes, Gerber X2 allows for the inclusion of custom attributes in the file metadata. This enables designers to convey project-specific information or requirements to the fabricator, enhancing communication and collaboration.

4. Do I need special software to view or edit Gerber X2 files?

While most modern PCB design tools support Gerber X2, you can also use specialized Gerber Viewers or editors to inspect and modify the files if needed. There are several free and commercial options available, such as GerbView, ViewMate, and CAM350.

5. Are there any additional costs associated with using Gerber X2?

No, there are no additional costs associated with using Gerber X2. It is an open and freely available file format that can be generated by most PCB design software without any extra licenses or fees.
