There is no universal PCBA unit price—quotes stack multiple variables. Understanding them helps R&D make manufacturable trade-offs early and helps procurement compare bids fairly.
PCB and panel design
- Layer count, thickness, trace/space, surface finish (HASL, ENIG, OSP, etc.)
- Panelization, V-cut or routing, controlled impedance requirements
BOM and materials
Component count, share of BGAs/connectors, and scarce ICs drive material cost and placement time. Turnkey quotes should define the AVL and alternate-part policy.
Process difficulty
01005, double-sided SMT, selective wave, hand-solder joints, conformal coat, and X-Ray sampling rates all map to labor and equipment loading.
Test and compliance
New ICT/FCT fixtures, programming and calibration, burn-in duration, and batch traceability documents feed NRE and per-unit allocation.
Volume and lead time
Higher volume spreads setup and material overhead; expedited builds may add overtime, line priority, and air freight. PCBA PARTNER recommends sharing forecasts and milestones at RFQ for accurate tiered pricing.
