Jlcpcb

This gives Claude detailed knowledge of JLCPCB's PCB fabrication and assembly service, including their parts library (698 basic parts with no extra fee, 300k+ extended parts at $3 each), BOM/CPL format requirements, design rules down to 5mil traces, and the rotation offset quirks that trip people up on SOT-23s and QFNs. It's built for the common workflow of ordering bare prototype boards with stencils during development, then switching to fully assembled production runs using LCSC parts. The skill covers both Economic assembly (top side SMD only) and Standard (both sides plus through-hole), and importantly includes the exact column headers JLCPCB expects in your BOM CSV or the upload will just fail. Works alongside the kicad, bom, and lcsc skills for the full manufacturing pipeline.

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.
