## Description

JLCPCB PCB fabrication and assembly, BOM/CPL generation, basic vs extended parts, assembly constraints, design rules, ordering workflow. Use with KiCad for JLCPCB manufacturing. Use this skill when the user mentions JLCPCB, wants to order PCBs or assembled boards, needs prototype bare PCBs and stencils, wants to know JLCPCB design rules and capabilities, or is asking about PCB manufacturing costs or turnaround times. For gerber/CPL export, stencil ordering, and BOM management, see the `bom` skill.

# 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.

## Assembly Parts Library

### Part Categories

| Category | Description | Assembly Fee |
|----------|-------------|--------------|
| **Basic** | Common parts (resistors, caps, diodes, common ICs) pre-loaded on pick-and-place machines | No extra fee |
| **Extended** | 300k+ less common parts loaded on demand | $3 per unique extended part |

> JLCPCB occasionally promotes a subset of frequently-used extended parts with a discounted or waived feeder fee (the program's name and terms shift over time). Check the current JLCPCB parts library page for any specific extended part before assuming the standard $3 fee applies.
