Convert SCH to GBR

Understanding SCH and GBR file formats

SCH files are schematic diagram files commonly used in electronic design automation (EDA) software such as EAGLE, KiCad, or OrCAD. These files represent the logical design of an electronic circuit, showing components and their connections.

GBR files (Gerber files) are standard in the PCB (Printed Circuit Board) manufacturing industry. They contain the physical layout information required to fabricate a PCB, such as copper layers, solder masks, and silkscreens.

Why convert SCH to GBR?

Converting an SCH file to a GBR file is a crucial step in the PCB design workflow. While SCH files define the circuit logic, GBR files are needed for manufacturing the actual board. The conversion process typically involves creating a PCB layout from the schematic and then exporting the layout as Gerber files.

How to convert SCH to GBR

Direct conversion from SCH to GBR is not possible, as they serve different purposes. The standard workflow is:

1. Open your SCH file in your EDA software (e.g., KiCad or EAGLE).
2. Create a PCB layout from the schematic (usually via Tools → Annotate Schematic and Tools → Generate Netlist).
3. Switch to the PCB editor and import the netlist to generate the board layout.
4. Once the PCB layout is complete, export Gerber files using File → Plot or File → Export → Gerber.

Best software for SCH to GBR conversion

• KiCad: Free and open-source, supports both schematic capture and Gerber export.
• Autodesk EAGLE: Popular for hobbyists and professionals, offers seamless SCH to GBR workflow.
• Altium Designer: Industry-standard for advanced PCB design and manufacturing outputs.

Tips for successful conversion

• Always verify your schematic for errors before generating the PCB layout.
• Double-check Gerber files with a Gerber viewer before sending them to a manufacturer.
• Consult your PCB manufacturer for specific Gerber file requirements.
