Fab-House Integration

PCB and assembly houses with developer-friendly upload, preview, and ordering flows.

The boring-but-critical "where do I send these Gerbers" layer. Pairs with PCB Panelization, Gerber Viewers, and BOM Tooling.

Fast / cheap / online (the "just send it" tier)

★ JLCPCB — by far the cheapest of the major fab houses; SMT assembly is bundled and the LCSC parts library makes "designed for JLC assembly" a real workflow. KiCad and EasyEDA upload flows are excellent. Quality is more than acceptable for prototypes and most production volumes.
★ PCBWay — a touch pricier than JLC, broader manufacturing services (flex, rigid-flex, advanced finishes, CNC, 3D print, sheet metal, injection mold, full assembly). Good for the "I need one shop for the whole product" case.
Aisler — Germany / EU; ships fast in Europe; developer-friendly project pages and a clean "share your project" flow. Pricier than JLC but no customs friction inside the EU. Strong KiCad relationship.
OSH Park — US (Oregon); the famous purple-soldermask hobby fab; community-loved, perfect-quality 2/4-layer service shared-panel pricing. Slower turn than JLC.
AllPCB, Seeed Fusion, NextPCB, Elecrow, MakerPCB — China-based mid-tier alternates; usually a stand-in if JLC is overloaded.

OSH Park — see above.
MacroFab — US; turnkey assembly with a developer-friendly portal and APIs.
Sierra Circuits, Advanced Circuits (4PCB) — US, established, paid like a "real" fab.
Eurocircuits — EU; established mid-tier; PCB Visualizer is genuinely useful.
Aisler — EU; see above.
Royal Circuits, Bay Area Circuits — US niche.

MacroFab API — one of the few fab houses with a public, well-documented REST API for quotes and orders.
JLCPCB / PCBWay: no first-party public APIs in 2026; integration is via their EasyEDA / KiCad plugins.
Aisler has a partner-facing API for some workflows.

★ OSH Park Shared Projects — anyone can buy your board; the community's de-facto OSHW PCB pin-board.
★ Aisler Project Pages — buy-this-project links; gracious to OSHW projects.
JLCPCB Open-Source Hardware Lab — JLC's OSHW promotion program; sponsors free runs of qualifying projects.
PCBWay Shared Project / Sponsorship — similar.
