How to export Diptrace PCB to Gerber files

Diptrace is a powerful PCB design software that offers a wide range of features to help designers create and manufacture printed circuit boards (PCBs). One of the most important steps in the PCB manufacturing process is exporting the design to Gerber files, which are the industry-standard file format used by PCB manufacturers. In this article, we will guide you through the process of exporting your Diptrace PCB to Gerber files.

Understanding Gerber Files

Before we dive into the export process, it's essential to understand what Gerber files are and why they are so crucial in PCB manufacturing. Gerber files are vector image files that describe the various layers of a PCB design, such as the copper layers, solder mask layers, and silkscreen layers. Each layer is represented by a separate Gerber file, and these files are combined by the PCB manufacturer to create the final product.

Gerber files use a standardized format that is recognized by most PCB manufacturers, ensuring that your design can be accurately reproduced. This format includes information about the size and shape of each layer, as well as the location of copper features, drill holes, and other components.

Preparing Your Diptrace PCB for Export

Before you can export your Diptrace PCB to Gerber files, you need to ensure that your design is complete and error-free. Here are some steps to follow:

1. Check your design rules: Make sure that your design adheres to the design rules you've set up. This includes checking for errors like overlapping copper, incorrect clearances, and any other violations.
2. Run a design rule check: Diptrace provides a built-in design rule check (DRC) tool that can help you identify and fix any errors or violations in your design. Run the DRC and address any issues it finds.
3. Check your component placement: Ensure that all components are correctly placed and oriented on the PCB. Double-check the footprints and pin assignments for each component.
4. Review your design: Take a final look at your PCB design, checking for any obvious errors or issues that may have been missed during the previous steps.

Exporting to Gerber Files

Once you've thoroughly checked and verified your design, you're ready to export to Gerber files. Here's how to do it:

1. Open the Gerber Export Wizard: In Diptrace, go to the "File" menu and select "Export PCB to Gerber" or click on the corresponding toolbar icon.
2. Select the layers to export: In the Gerber Export Wizard, you'll be prompted to select the layers you want to include in the Gerber files. Typically, you'll need to export the following layers: Top Copper Bottom Copper Top Solder Mask Bottom Solder Mask Top Silkscreen Bottom Silkscreen Drill Drawing (for plated holes) Drill Guide (for non-plated holes) You can select or deselect layers based on your specific requirements and the instructions provided by your PCB manufacturer.
3. Configure export settings: After selecting the layers, you'll have the option to configure various export settings. These settings may include: Units (mil or mm) Coordinate format Aperture emulation Gerber file format (RS-274X or RS-274D) Output directory Ensure that you configure these settings according to your PCB manufacturer's requirements or industry standards.
4. Review and export: Once you've selected the layers and configured the export settings, review your choices and click "Export" to generate the Gerber files.

After the export process is complete, you should have a set of Gerber files representing each layer of your PCB design. These files are typically accompanied by additional files, such as drill files, pick-and-place files, and design documentation, depending on the requirements of your PCB manufacturer.

Sending Gerber Files to Your PCB Manufacturer

Once you have your Gerber files, you'll need to send them to your chosen PCB manufacturer. Most manufacturers will provide specific instructions on how to submit your files, which may include:

• Creating a compressed archive (e.g., ZIP or RAR) containing all the necessary files
• Uploading the files to the manufacturer's website or FTP server
• Sending the files via email or a file-sharing service

Be sure to follow the manufacturer's instructions carefully to ensure that your files are received and processed correctly.

FAQs

1. Q: Do I need to export all layers to Gerber files? A: It depends on your specific requirements and the instructions provided by your PCB manufacturer. Typically, you'll need to export the copper layers, solder mask layers, silkscreen layers, and drill files. However, some manufacturers may require additional layers or have specific preferences.
2. Q: What is the difference between RS-274X and RS-274D Gerber file formats? A: RS-274X is the newer and more widely used Gerber file format, while RS-274D is an older format. RS-274X supports advanced features like aperture macros and region statements, which can result in more efficient and compact file sizes. However, some older systems may still require the RS-274D format, so it's essential to check with your PCB manufacturer.
3. Q: Can I export Gerber files for a partially completed design? A: While it's technically possible to export Gerber files for an incomplete design, it's generally not recommended. Exporting an incomplete or unverified design can lead to errors, missing components, or other issues that may cause problems during manufacturing. It's best to complete and thoroughly check your design before exporting to Gerber files.
4. Q: How can I ensure that my Gerber files are accurate? A: To ensure the accuracy of your Gerber files, follow these steps: Run a comprehensive design rule check (DRC) in Diptrace Visually inspect your PCB design for any errors or issues Use the Gerber viewer tool in Diptrace to preview the exported files Consider sending your Gerber files to your PCB manufacturer for a pre-production review
5. Q: What should I do if I encounter errors or issues during the export process? A: If you encounter errors or issues during the export process, first, review your design and export settings to ensure that everything is correct. If the problem persists, consult the Diptrace documentation or seek assistance from the Diptrace support community or your PCB manufacturer.

Conclusion

Exporting your Diptrace PCB to Gerber files is a crucial step in the PCB manufacturing process. By following the steps outlined in this article, you can ensure that your design is properly prepared and exported to industry-standard Gerber files. Remember to thoroughly check your design, configure the export settings correctly, and follow your PCB manufacturer's instructions for submitting the files. With careful attention to detail, you can streamline the manufacturing process and ensure that your PCB design is accurately reproduced.
