Schematic to PCB: how KiCad and EasyEDA do it, and what AI actually automates
No program turns a drawing of a circuit into a finished board by itself. Here is what "convert schematic to PCB" really does in KiCad and EasyEDA, the order of the steps that follow, and where the AI tools fit.
What the conversion does, and does not
A schematic says what connects to what. A PCB says where every part sits and where every track runs. "Convert to PCB" bridges the two: it takes each symbol's footprint, puts the footprints on the board, and draws the connections as thin straight lines (the ratsnest). It does not place the parts sensibly or route a single track. That is the PCB layout, and it is the part that takes the time.
How to convert a schematic to a PCB layout in EasyEDA
- Finish the schematic and give every symbol a footprint. Check them in Design > Footprint Manager.
- Click "Convert to PCB" on the toolbar, or Design > Convert to PCB.
- If a row turns red in the dialog, that part has no matching footprint: click it, assign one in the Footprint Manager, and convert again.
- In the PCB editor, draw the board outline, then drag the footprints into place, following the ratsnest.
- Route the tracks by hand (or try the autorouter for a first pass), add a ground pour, and run the design rule check.
- After any later change to the schematic, use Design > Update PCB rather than converting again.
- Fabrication > PCB Fabrication File (Gerber) exports the zip a board house needs.
The same in KiCad
- In the schematic editor, assign footprints (Tools > Assign Footprints) and run the electrical rules check.
- Open the PCB editor and press F8, "Update PCB from Schematic". The footprints arrive in a heap with their ratsnest.
- Draw the outline on Edge.Cuts, place the parts, route, pour copper zones, then run the design rules check.
- File > Fabrication Outputs > Gerbers, and Generate Drill Files, then zip them together.
KiCad or EasyEDA?
| KiCad | EasyEDA | |
|---|---|---|
| Price | Free, open source | Free |
| Runs | Installed: Windows, macOS, Linux | In the browser, or a desktop app |
| Parts library | Large, community made | LCSC parts, linked to JLCPCB stock |
| Files | Yours, plain text | In your account, exportable |
| Best for | Anything you will maintain for years | A quick board ordered from JLCPCB |
Both are proper PCB drawing software, and both export the standard Gerber files that every board house reads. Either way, open the Gerbers in a separate viewer before ordering: what gets made is the files, not what the editor showed.
What "schematic to PCB converter AI" really means
The AI tools of 2026 automate the layout step that comes after the conversion. Quilter and DeepPCB take a finished schematic and board outline and place and route them, using reinforcement learning, and hand back a layout to check. Flux works in the browser as an assistant through the whole design. None of them removes the engineer: high-speed signals, RF, length matching, thermal design and manufacturability still need a person, and every autorouted board needs a careful review before it is ordered.
Where this site comes in
Before a schematic exists, a sketch can become a board directly: draw the copper, photograph it, and etch it or have it made. After the layout is done, the Gerbers need checking, printing for etching, or turning into pictures and DXF for the enclosure.
