One of 13 test cases the skill fixed. Same model, same prompt, with and without the skill.
I only need 2 populated prototype boards assembled for testing. What is the minimum board quantity required when ordering PCB assembly at JLCPCB?
| Checked | Without skill | With skill |
|---|---|---|
| State that the minimum order quantity for PCB assembly is 5 PCBs. | Missed | Passed |

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 | 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.
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.
