Why you should supply us with Gerber X2 files.

Introduction to Gerber X2

Gerber X2 is a powerful and modern file format used in the printed circuit board (PCB) industry. It is an extension of the widely used Gerber format, which has been the standard for PCB fabrication for decades. Gerber X2 offers numerous advantages over its predecessor, making it the preferred choice for many PCB designers and manufacturers.

In this article, we will explore the benefits of using Gerber X2 files and why you should consider supplying them to us for your PCB projects. We will dive into the technical aspects of Gerber X2, its improved features, and how it can streamline the PCB manufacturing process.

What is Gerber X2?

Gerber X2 is a file format that contains all the necessary information for PCB fabrication, including the copper layers, solder mask, silkscreen, and drill data. It is an open-source format developed by Ucamco, the company behind the original Gerber format.

Gerber X2 builds upon the strengths of its predecessor while introducing new features and enhancements. Some of the key improvements in Gerber X2 include:

• Embedded aperture definitions
• Attribute data
• Improved clarity and readability
• Standardized file structure

These features make Gerber X2 more efficient, accurate, and user-friendly compared to the original Gerber format.

Embedded Aperture Definitions

One of the most significant advantages of Gerber X2 is its ability to embed aperture definitions directly into the file. In the original Gerber format, aperture definitions were stored in a separate file, which could lead to confusion and errors if the files were not properly managed.

With Gerber X2, the aperture definitions are included within the main file, ensuring that all the necessary information is in one place. This eliminates the need for separate aperture files and reduces the risk of mismatched or missing apertures.

Attribute Data

Gerber X2 introduces the concept of attribute data, which allows for the inclusion of additional information within the file. Attributes can be used to specify various properties of the PCB, such as:

• Layer types (copper, solder mask, silkscreen, etc.)
• Copper weights
• Finish types
• Material specifications

By including attribute data, Gerber X2 files provide a more comprehensive and self-contained description of the PCB. This information can be used by the manufacturer to ensure that the PCB is fabricated according to the designer’s specifications.

Improved Clarity and Readability

Gerber X2 files are designed to be more human-readable than their predecessor. The format uses clear and descriptive names for layers and attributes, making it easier for both designers and manufacturers to understand the contents of the file.

For example, instead of using cryptic layer names like “L01” or “L02”, Gerber X2 allows for descriptive names such as “Top_Copper” or “Bottom_Solder_Mask”. This clarity reduces the likelihood of misinterpretation and errors during the manufacturing process.

Standardized File Structure

Gerber X2 introduces a standardized file structure that ensures consistency across different PCB designs. The format specifies a set of file extensions and naming conventions that should be used for each type of layer or data.

For example, the file extension for the top copper layer is “.gtl”, while the bottom copper layer uses “.gbl”. This standardization makes it easier for manufacturers to identify and process the files, reducing the chances of confusion or mistakes.

Benefits of Using Gerber X2

Now that we have a better understanding of what Gerber X2 is and its key features, let’s explore the benefits of using this format for your PCB projects.

Increased Accuracy

One of the primary benefits of using Gerber X2 is increased accuracy in PCB fabrication. The embedded aperture definitions and attribute data provide a complete and unambiguous description of the PCB, reducing the risk of misinterpretation or errors.

With Gerber X2, there is no need for manufacturers to make assumptions or guesses about the designer’s intent. All the necessary information is clearly defined within the file, ensuring that the PCB is fabricated exactly as intended.

Improved Efficiency

Gerber X2 files can also improve the efficiency of the PCB manufacturing process. The standardized file structure and naming conventions make it easier for manufacturers to process and organize the files, reducing the time and effort required for setup and preparation.

Additionally, the self-contained nature of Gerber X2 files eliminates the need for separate aperture files, further streamlining the process. This can lead to faster turnaround times and reduced costs for both the designer and the manufacturer.

Enhanced Communication

Using Gerber X2 files can enhance communication between PCB designers and manufacturers. The clear and descriptive layer names and attribute data provide a common language that both parties can understand, reducing the potential for misunderstandings or miscommunications.

Gerber X2 also supports the inclusion of comments and notes within the file, allowing designers to provide additional context or instructions to the manufacturer. This level of communication can help ensure that the final product meets the designer’s expectations.

Compatibility and Future-Proofing

Gerber X2 is an open-source format that is widely supported by PCB design software and manufacturing equipment. This widespread compatibility ensures that your Gerber X2 files can be easily shared and processed by different manufacturers and tools.

Moreover, as an extension of the original Gerber format, Gerber X2 is backward compatible. This means that manufacturers who are still using older equipment or software can still process Gerber X2 files, albeit without taking advantage of the new features and enhancements.

By using Gerber X2, you are future-proofing your PCB designs and ensuring that they can be easily adapted to new technologies and processes as the industry evolves.

How to Generate Gerber X2 Files

Generating Gerber X2 files is a straightforward process that can be done using most modern PCB design software. Here are the general steps involved:

1. Complete your PCB design using your preferred design software.
2. Select the “File” menu and choose “Export” or “Generate Output”.
3. In the export options, select “Gerber” as the output format.
4. Choose “Gerber X2” as the specific format version.
5. Configure the export settings, such as the layer selection and file naming conventions.
6. Generate the Gerber X2 files and review them for accuracy.

It’s important to note that the exact steps may vary slightly depending on the design software you are using. Consult your software’s documentation or support resources for specific instructions on generating Gerber X2 files.
