# JLCPCB — PCB Fabrication & Assembly 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. ## Related Skills | 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 | ## Assembly Parts Library ### Part Categories | 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 assem
