Convert BRD to GERBER

Understanding BRD and Gerber file formats

BRD files are proprietary PCB (Printed Circuit Board) design files created by EAGLE, Altium, or other PCB design software. They contain all the layout, component, and routing information needed to manufacture a PCB. Gerber files, on the other hand, are the industry-standard format for PCB fabrication. They describe each layer of the PCB (copper, solder mask, silkscreen, etc.) in a universally recognized way, allowing manufacturers to produce the physical board.

Why convert BRD to Gerber?

PCB manufacturers require Gerber files to fabricate your design. While BRD files are useful for editing and design, they are not suitable for direct manufacturing. Converting your BRD file to Gerber ensures compatibility with fabrication processes and prevents errors during production.

How to convert BRD to Gerber

The conversion process depends on the software used to create the BRD file. Here are the most common methods:

• Autodesk EAGLE:
  1. Open your BRD file in EAGLE.
  2. Go to File → CAM Processor.
  3. Load the Gerber job file (e.g., gerb274x.cam).
  4. Click Process Job to generate Gerber files for each PCB layer.
  5. Export the generated files for manufacturing.
• Altium Designer:
  1. Open your PCB project.
  2. Go to File → Fabrication Outputs → Gerber Files.
  3. Configure the output settings as needed.
  4. Click OK to generate and save the Gerber files.

Best software for BRD to Gerber conversion

The most reliable way to convert BRD to Gerber is to use the original PCB design software:

• Autodesk EAGLE (for .brd files from EAGLE)
• Altium Designer (for .brd files from Altium)

For users without access to these tools, GerbView or Online Gerber Viewers can sometimes import BRD files and export Gerber, but results may vary. Always verify the output before sending files to a manufacturer.

Tips for successful conversion

• Double-check layer assignments and output settings before exporting.
• Use the DRC (Design Rule Check) feature to catch errors before conversion.
• Preview Gerber files with a Gerber viewer to ensure accuracy.
