Prepare a Gerber fabrication package

Choose your PCB design software

Export Gerber artwork and drilling data from the same final design revision. Choose a guide below for the software workflow, then complete the checks on this page.

• Export Gerber and drill files from KiCad
• Export Gerber and NC drill files from Altium Designer
• Export Gerber files from EasyEDA Standard and Pro
• Export Gerber and drill files from Autodesk EAGLE
• Export Gerber and drill files from Proteus
• Export Gerber and Excellon files from Sprint-Layout
• Export Gerber and NC drill files from PCB Wizard
• Export Gerber and drill files from CircuitMaker
• Export Gerber and N/C drill files from DipTrace
• Export Gerber production files from Fritzing
• Check PCBE Gerber files and resolve import errors

Include the manufacturing layers

• Gerber data for every copper layer in the intended stack-up.
• Solder mask and silkscreen layers used by the design.
• A clearly defined board outline.
• Drill files for holes, with plated and non-plated information identified.
• A fabrication drawing or notes for requirements not represented by the layer files.

Check the package

Export all files from the same final revision and use consistent units and coordinates. Open the export in a viewer to check the outline, layer alignment and hole locations. Remove obsolete exports so the archive contains one unambiguous design revision.

Use clear filenames that identify each layer. Keep the original CAD project separately for future revisions.

Upload and verify

Put the fabrication files in an archive and upload it through PCB Instant Quote. Check the size and layer count shown after upload. Describe any ambiguity in the PCB Remark field instead of relying on a filename alone.

Layer names and common file problems

• Gerber file names and layer mapping
• Check drill files, tool tables and coordinate alignment
• Prepare solder mask-defined pads for manufacturing

Bare PCB or PCB assembly?

For bare PCBs, upload the Gerber ZIP including drills. Assembly also requires a matching BOM and placement file. Paste layers are used for stencil manufacture; solder-mask layers describe exposed copper. See assembly file requirements.
