JLCPCB is a PCB fabrication and assembly service based in Shenzhen, China. It is a sister company to LCSC Electronics (common ownership) — they share the same parts library.
Guides PCBWay fabrication and assembly orders: turnkey/consigned options, BOM formats, design rules, workflow. Alternative to JLCPCB for KiCad projects with non-LCSC parts.
Searches registries and web for electronic components and reusable subcircuits to add to Zener PCB projects. Use during board, module, or subsystem design with pcb search and pcb new component.
Conducts multi-round deep research on GitHub repos via API and web searches, generating markdown reports with executive summaries, timelines, metrics, and Mermaid diagrams.

JLCPCB is a PCB fabrication and assembly service based in Shenzhen, China. It is a sister company to LCSC Electronics (common ownership) — they share the same parts library.
Typical usage: Order bare prototype PCBs + framed stencil from JLCPCB during prototyping (parts sourced separately from DigiKey/Mouser, hand-assembled in lab). For production runs (100s qty), order fully assembled boards from JLCPCB using LCSC parts. PCBWay is an alternative assembler. For component searching, see the lcsc skill. For BOM management, gerber/CPL export, and stencil ordering, see the bom skill.
| Skill | Purpose |
|---|---|
kicad | Read/analyze KiCad project files, DFM scoring against JLCPCB capabilities |
bom | BOM management, gerber/CPL export, stencil ordering |
digikey | Search DigiKey (prototype sourcing, primary — also preferred for datasheet downloads via API) |
mouser | Search Mouser (prototype sourcing, secondary) |
lcsc | Search LCSC (production sourcing — JLCPCB uses LCSC parts library) |
pcbway | Alternative PCB fabrication & assembly |
emc | EMC pre-compliance risk analysis — run before fab to catch EMC issues |
spice | SPICE simulation — verify analog subcircuits before committing to fab |
| Category | Description | Assembly Fee |
|---|---|---|
| Basic | ~698 common parts (resistors, caps, diodes, etc.) pre-loaded on pick-and-place machines | No extra fee |
| Preferred Extended | Frequently used extended parts | No feeder loading fee (Economic assembly) |
| Extended | 300k+ less common parts loaded on demand | $3 per unique extended part |
Every assembly component is identified by an LCSC Part Number (Cxxxxx, e.g., C14663). This is the definitive identifier for BOM matching. See the lcsc skill for searching parts.
https://jlcpcb.com/parts/componentSearch?searchTxt=<query>https://jlcpcb.com/parts/basic_partsJLCPCB accepts CSV, XLS, or XLSX BOMs with these columns:
| Column | Required | Description |
|---|---|---|
Comment / Value | Yes | Component value (e.g., 100nF, 10k) |
Designator | Yes | Reference designators, comma-separated (e.g., C1,C2,C5) |
Footprint | Yes | Package/footprint name |
LCSC Part # | Recommended | LCSC part number (Cxxxxx) — guarantees exact match |
The column header for LCSC numbers must be exactly "LCSC Part #" or "LCSC Part Number" — typos cause upload failures.
LCSC field to each symbol with the LCSC part numberReference -> DesignatorValue -> CommentFootprint -> FootprintLCSC -> LCSC Part #For gerber export settings, CPL format, and stencil ordering, see the bom skill.

JLCPCB's pick-and-place uses different rotation conventions than KiCad for some footprints. Common offsets:
| Footprint Family | Typical Offset |
|---|---|
| SOT-23, SOT-23-5, SOT-23-6 | +180° |
| SOT-223 | +180° |
| SOIC-8, SOIC-16 | +90° or +270° |
| QFN (all sizes) | +90° |
| SMA/SMB/SMC diodes | +180° |
| USB-C connectors | Varies — check datasheet |
