Frequently Asked Questions

Q1: What is the correct layer sequence for exporting Gerber files in DipTrace?

A1: The recommended layer sequence is: Top Overlay, Top Paste, Top Solder Mask, Top Copper, Internal Layers (if any), Bottom Copper, Bottom Solder Mask, Bottom Paste, and Bottom Overlay. Drill files should be exported separately in Excellon format.

Q2: How do I verify my Gerber files are correct before sending them to manufacturing?

A2: After export, use a Gerber viewer to check: layer alignment, presence of all required layers, correct board dimensions, proper drill hole locations, and component placement. Also verify that copper layers, solder mask, and silkscreen align properly.

Q3: What are the most common export settings mistakes in DipTrace?

A3: Common mistakes include incorrect units (metric vs. imperial), wrong number format (leading vs. trailing zeros), improper layer selection, and forgotten drill files. Always verify these settings before export and use the recommended 4:4 format with leading zeros.

Q4: Why are some features missing in my exported Gerber files?

A4: Missing features usually result from incorrect layer visibility settings, improper export configuration, or features being on disabled layers. Ensure all relevant layers are visible and properly configured in the export settings dialog.

Q5: How do I handle different drill sizes in DipTrace Gerber export?

A5: DipTrace automatically generates a drill file with all hole sizes. Ensure you export both plated and non-plated holes if your design requires them. The drill file should be in Excellon format with metric units for consistency.
