Frequently Asked Questions (FAQ)

Q1: Why are my Gerber files missing some PCB features?

This usually occurs due to incorrect layer selection or export settings. Ensure all necessary layers are selected and properly configured in the export dialog. Also, verify that all features are on their correct layers in the PCB design.

Q2: How can I verify my Gerber files before sending them to manufacturing?

Use a Gerber viewer software to check all layers, ensure proper alignment, and verify dimensions. Popular viewers include GerbView, CAM350, or online viewers provided by PCB manufacturers. DipTrace also includes a built-in preview feature.

Q3: What’s the difference between RS-274X and RS-274D Gerber formats?

RS-274X is the newer, extended format that includes aperture definitions within the file, making it more self-contained. RS-274D is older and requires separate aperture files. DipTrace primarily uses RS-274X for better compatibility with modern manufacturing processes.

Q4: Why do I need to include a drill file with my Gerber files?

The drill file (.TXT or .XLN) contains essential information about hole locations, sizes, and types that isn’t included in the Gerber layers. This file is crucial for the PCB manufacturer to properly drill all holes in your board.

Q5: How can I optimize my Gerber export process for complex boards?

Create a checklist including:

• Layer verification
• DRC completion
• Export settings confirmation
• File naming conventions
• Post-export verification This ensures consistency and reduces errors in the export process.
