Flux is an AI-powered PCB design tool that runs in your browser. Plan your schematic, lay out your board, and export manufacturing-ready files for PCBWay: all in one place. No install. Free to start.
Ships to manufacturers trusted by engineers worldwide:
If you're ordering from PCBWay, you already know what you're building. The hard part is getting from idea to a board that passes DRC, has a clean layout, and generates error-free manufacturing files.
Flux is a full browser-based EDA tool with AI built into every step:
Describe what you want to build. Flux understands your goals, suggests approaches, and maps out a design plan before you've drawn a single trace.
Flux generates a complete schematic, automatically selects components with real part data, and flags issues as you go. You steer the design, Flux builds it out.
Place your components, run AI-assisted routing, and check DRC in real time: tuned to PCBWay's manufacturing capabilities. Flux catches violations before they become respins.
Export Gerber files, BoM, and pick-and-place: pre-formatted for PCBWay. Upload and order. No manual column mapping. No spec hunting.
"Designed and manufactured the entire product in Flux, taking it from concept to production without external EE help. The device raised $187K on Indiegogo—proof of both market demand and his ability to deliver using Flux."
Flux ships a PCBWay manufacturer template with PCBWay's design constraints already loaded. Start your project, and DRC checks your layout against PCBWay's capabilities as you work. By the time you're ready to order, you know the board will pass.
Flux's AI has access to real-time component data — stock levels, footprints, datasheets — and surfaces the right parts in context as you design.
When your design is done, Flux generates your Gerber files, BoM (pre-formatted for PCBWay), and pick-and-place CSV together. Upload to PCBWay and you're ready to order.
Flux is real-time multiplayer. Multiple engineers can work on the same schematic, layout, and BOM simultaneously, with comments on specific parts. Everyone sees the latest version, always.
Nabhan built an IoT-enabled organ-on-chip platforms for drug discovery and biological barrier modeling.
Give Flux a job and it plans, designs, and exports your board — ready to order on PCBWay.
START DESIGNING WITH AI
Flux is an AI-powered PCB design tool that runs in your browser. It handles schematic capture, PCB layout, component selection, DRC, and manufacturing file export, with AI assistance at every step. You describe what you want to build, and Flux helps you get there.
Start your project with Flux's PCBWay manufacturer template. PCBWay's design rules are pre-loaded, so DRC checks your layout against PCBWay's manufacturing capabilities as you work. When you're ready to order, export your Gerber files, BoM (already formatted for PCBWay), and pick-and-place file in one step. Upload them to PCBWay and place your order.
No — they do different things. Flux is where you design your board. PCBWay is where you manufacture it. The two work together: Flux gets your design to a state that's ready to order on PCBWay, with the right files in the right format.
PCBWay needs Gerber files (board artwork and drill data), a Bill of Materials if you want PCBA, and a pick-and-place file for component placement. Flux generates all three from a single export step, pre-formatted for PCBWay's system.
Yes. When you create a new project in Flux, you can search for and select the PCBWay manufacturer template. This loads PCBWay's design constraints into your project automatically, so DRC flags any violations against PCBWay's spec as you design. No manual rule entry required.
Yes. Flux's AI helps at every step — it explains decisions, suggests components, generates schematics, and catches mistakes before they become expensive. If you can describe what you want to build, Flux can help you design it.
Yes. Flux has manufacturer templates and BoM formats for JLCPCB, Seeed Studio, OSH Park, Aisler, AllPCB, Eurocircuits, and others. If you're using PCBWay now but want flexibility later, your designs stay in Flux and you choose which fab to export for.
Free to design. The free plan includes full schematic and layout tools, AI assistance, and all manufacturing file exports including PCBWay-ready Gerbers, BoM, and pick-and-place. Paid plans add unlimited projects and team collaboration.
In-app AI chat, documentation, YouTube tutorials, and an active Slack community. Flux engineers are in the community and most questions get answered quickly.
