Convert GERBER to GBR

Understanding Gerber and GBR file formats

Gerber files are the industry standard for PCB (Printed Circuit Board) design data. They describe the copper layers, solder mask, legend, and other details necessary for manufacturing PCBs. The term "Gerber" often refers to the RS-274X format, which is widely used in modern PCB fabrication.

GBR files are essentially Gerber files themselves. The ".gbr" extension is commonly used to denote Gerber files, especially in software that requires explicit file extensions for different layers or processes. In practice, converting a Gerber file to a GBR file usually means renaming the file extension or exporting the Gerber data in a format compatible with specific PCB tools.

How to convert Gerber to GBR

Since Gerber and GBR files are fundamentally the same, conversion is straightforward. If your Gerber file has a different extension (such as ".pho" or ".art"), you can simply rename it to ".gbr". However, if you need to ensure compatibility or re-export the file, PCB design software can help.

Recommended software for Gerber to GBR conversion

• KiCad: Open your PCB project, then use File → Plot and select the Gerber format. Save the output with a ".gbr" extension.
• Altium Designer: Open your PCB, go to File → Fabrication Outputs → Gerber Files, and specify the ".gbr" extension when exporting.
• Gerbv (free Gerber viewer): Open your Gerber file and use File → Save As to export with a ".gbr" extension.

Tips for successful conversion

• Always verify the output file in a Gerber viewer to ensure data integrity.
• Maintain consistent naming conventions for different PCB layers (e.g., top.gbr, bottom.gbr).
• Check with your PCB manufacturer for preferred file extensions and formats.

Summary

Converting a Gerber file to a GBR file is typically a matter of renaming the extension or re-exporting the file using PCB design software. KiCad, Altium Designer, and Gerbv are excellent tools for this process, ensuring your files are ready for PCB manufacturing.
