PCBWay — PCB Fabrication & Assembly

PCBWay is a PCB fabrication and assembly service based in Shenzhen, China. It is an alternative to JLCPCB with similar capabilities and pricing.

Typical usage: Order bare prototype PCBs + framed stencil from PCBWay during prototyping (parts sourced separately from DigiKey/Mouser, hand-assembled in lab). For production runs (100s qty), order fully assembled boards from PCBWay using turnkey component sourcing (PCBWay sources parts by MPN). JLCPCB is the primary alternative. For BOM management, gerber/CPL export, and stencil ordering, see the bom skill.

Key Differences from JLCPCB

| Feature | PCBWay | JLCPCB | |---------|--------|--------| | Component sourcing | Turnkey (PCBWay sources by MPN) | LCSC parts library (you provide LCSC PNs) | | Parts library | No fixed library — sources globally | LCSC library (basic/extended parts) | | Assembly fee model | Quote-based per project | Per-part fees (basic free, extended $3 each) | | BOM format | MPN-based (manufacturer part numbers) | LCSC PN-based |

When to use PCBWay over JLCPCB:

Parts not available on LCSC — PCBWay sources globally by MPN
Need turnkey sourcing — provide MPNs, PCBWay handles procurement
Prefer quote-based pricing over per-part fee model
Need consigned/kitted assembly (you ship parts to PCBWay)

Assembly Options

| Option | Description | |--------|-------------| | Turnkey | PCBWay sources all parts by MPN — you just provide the BOM | | Partial turnkey | PCBWay sources some parts, you supply others | | Consigned/Kitted | You supply all parts, PCBWay assembles |

BOM Format for Assembly

PCBWay accepts XLS, XLSX, or CSV BOMs.

Turnkey / Partial Turnkey BOM

Line#,Qty,Designator,MPN,Manufacturer,Description,Package,Type
1,3,"C1,C2,C5",GRM155R71C104KA88D,Murata,100nF 16V X7R MLCC,0402,SMD
2,1,U1,ESP32-S3-WROOM-1-N16R8,Espressif,ESP32-S3 WiFi/BT module,ESP32-S3-WROOM-1,SMD

Required columns: | Column | Description | |--------|-------------| | Line# | Row number | | Qty | Quantity per board | | Designator | Reference designators (comma-separated) | | MPN | Manufacturer Part Number — PCBWay sources by this | | Manufacturer | Manufacturer name | | Description | Part description | | Package | Footprint/package name | | Type | SMD, THT (through-hole), or Hybrid |

For turnkey, the MPN is the critical field — PCBWay uses it to source parts from their global supply chain.

KiCad BOM Export for PCBWay

In KiCad, ensure MPN and Manufacturer fields are populated in symbol properties
Export via Edit Symbol Fields > Export CSV
Reformat columns to match PCBWay's expected format (add Line#, Qty, Type columns)

For gerber export settings and CPL format, see the bom skill — both JLCPCB and PCBWay use the same formats.

Ordering Workflow

Prototype Order (Bare PCB + Stencil)

Export gerbers from KiCad (see bom skill for export settings)
Upload gerbers to https://www.pcbway.com/orderonline.aspx — configure layers, thickness, color, qty
Order a framed stencil separately at https://www.pcbway.com/stencil.aspx
Order — PCBs and stencil typically arrive in ~1 week

Production Order (Assembled Boards)

Export gerbers from KiCad (see bom skill for export settings)
Export BOM as CSV with MPN, Manufacturer, Description, Package, Type columns
Export CPL (centroid/placement file) as CSV (see bom skill for format)
Upload gerbers to PCBWay — configure PCB specs
Select "PCB Assembly" — choose Turnkey, Partial Turnkey, or Consigned
Upload BOM and centroid files
Add assembly drawings/photos if needed (recommended for complex boards)
PCBWay reviews files and provides quote
Confirm and order

Tips

MPN is what matters — unlike JLCPCB (LCSC PNs), PCBWay sources globally by Manufacturer Part Number
Turnkey is easiest — just provide MPNs in BOM, PCBWay handles sourcing
Assembly requires manual quoting — unlike JLCPCB's instant pricing, PCBWay reviews your files and provides a custom quote (typically 1-2 business days). Factor this into your timeline.
Assembly drawings help — submit photos or annotated PDFs for complex placement
Lead time varies — turnkey assembly depends on component sourcing time; check with PCBWay
Rotation offsets — PCBWay may have different rotation conventions than KiCad; verify with assembly drawings
Solder mask colors — more options than JLCPCB (includes purple, matt variants)
Edge clearance — keep copper >=0.3mm from board edge
