Preparing Your Flux.ai Design for Gerber Export
Getting clean manufacturing files starts with proper design preparation. Flux.ai includes several features that help ensure your design is ready for fabrication before you ever hit the export button.
Running Design Rule Checks
Flux.ai’s automated design rule checking validates your layout against manufacturer specifications. Before exporting, always run a DRC to catch potential issues.
The platform checks for:
Rule Category
What It Validates
Trace Width
Minimum conductor dimensions
Clearance
Spacing between copper objects
Drill Size
Minimum hole diameters
Annular Ring
Pad-to-hole relationships
Via Specifications
Via dimensions and aspect ratios
Silkscreen Overlap
Text/graphics over pads
Board Outline
Proper edge clearances
Using Pre-configured Manufacturer Templates
Flux.ai simplifies DRC setup by providing pre-configured templates for popular manufacturers. When starting a new project, select the template matching your intended fabricator:
Navigate to the stackup settings in your project. Select from available manufacturer templates (JLCPCB, PCBWay, AISLER, etc.). The DRC rules automatically configure to match that manufacturer’s capabilities.
This approach eliminates the guesswork of setting minimum trace widths, drill sizes, and other parameters. You design to the manufacturer’s actual capabilities from the start.
Verifying Your BOM and Component Availability
One of Flux.ai’s standout features is real-time BOM management with live pricing and availability data. Before exporting for manufacturing, verify that all components are available.
The platform shows pricing and stock information in the top right corner of the interface. Components with availability issues are flagged, allowing you to find alternatives before committing to manufacturing.
Step-by-Step Guide to Export Gerber Files from Flux.ai
Now let’s walk through the actual process of exporting Gerber files from Flux.ai. The workflow is designed to be straightforward, with all manufacturing outputs accessible from a central export menu.
Step 1: Complete Your PCB Layout
Before exporting, ensure your design is complete. This includes all traces routed with no remaining airwires (ratsnest connections), copper pours properly filled, silkscreen elements positioned correctly, and the board outline properly defined.
In Flux.ai, you can verify completion by checking that no DRC errors remain and all schematic connections have been routed in the PCB view.
Step 2: Run Final Design Rule Check
Even if you’ve been running DRC throughout your design process, perform a final check before export. This catches any issues that might have been introduced during final edits.
Access the DRC function from the toolbar and review any warnings or errors. Address all critical errors before proceeding with export.
Step 3: Access the Export Menu
To export your design from Flux.ai, click the Flux logo in the upper left corner of the interface. This opens the main menu with project options. Navigate to the Export option to access all manufacturing file outputs.
Alternatively, you can access export functions from your project page when viewing your design.
Step 4: Select Gerber Export
From the export menu, select “Gerber” or “Gerber Format (RS-274X Extended)” depending on your interface version. Flux.ai will process your design and generate all necessary manufacturing files.
The export includes all copper layers, solder mask layers, silkscreen layers, board outline, and drill files in one package.
Step 5: Download the Manufacturing Package
After processing, Flux.ai provides a downloadable ZIP archive containing all your manufacturing files. Download this package and verify it contains all expected files.
The download typically includes Gerber files for each layer, Excellon drill file, and any additional outputs you’ve selected (BOM, pick and place, etc.).
Step 6: Export Additional Manufacturing Files
Beyond Gerber files, you’ll likely need additional files for assembly. From the same export menu, you can generate:
Bill of Materials (BOM): A complete component list with values, footprints, and reference designators. Flux.ai’s BOM includes real-time pricing data when available.
Pick and Place File: Component centroid data for automated assembly. This file contains X/Y coordinates, rotation, and layer information for each component.
IPC-D-356 Netlist: Test point data for electrical testing during manufacturing.

Working with AI Auto-Layout Before Export
Flux.ai’s AI Auto-Layout feature, powered by Flux Copilot, can automatically route your board before export. This is particularly useful for quickly generating manufacturable designs.
Using AI Auto-Layout
With AI Auto-Layout, Copilot handles the repetitive task of routing your board, delivering clean, human-like results. The process works as follows:
Complete your schematic and component placement. Invoke the AI Auto-Layout function. The AI iteratively improves the layout, showing multiple versions. Review and select your preferred version. Proceed with Gerber export.
Each option the AI generates is optimized for manufacturing, so you can be confident the resulting Gerber files will be manufacturable.
Verifying Gerber Files Before Manufacturing
Never send Gerber files to a manufacturer without verification. Flux.ai generates standard RS-274X files that can be viewed in any Gerber viewer.

Addressing Text Rendering Issues
Some users have reported that text in Gerber files may render differently than expected on manufactured boards. This occurs because manufacturers parse Gerber text data and may substitute fonts.
To ensure text appears exactly as designed, consider these approaches:
Use simple, standard fonts when possible. Verify critical text in your Gerber viewer. For logos or custom text, some users request that Flux convert text to graphical elements.
