XFPCB SMT PCB Assembly Service

XFPCB provides SMT PCB Assembly with PCB fabrication, component sourcing, SMT, through-hole assembly and inspection coordinated in one workflow. Your BOM, CPL, Gerber files and assembly notes are reviewed together so the build plan is clear before parts and boards move to the line.

For PCBA quotations, send Gerber files, BOM with manufacturer part numbers, pick-and-place data, assembly drawing, polarity notes, DNP list and test requirements. XFPCB can then align PCB fabrication, sourcing, assembly and inspection in one plan.

For SMT PCB Assembly, XFPCB combines engineering review, manufacturing preparation, quality inspection and export communication so your purchasing team can move from RFQ to delivery with a clear build plan.

Order Workflow

File Review

Review PCB files, BOM, CPL and assembly drawing together.

Parts Check

Check component availability, polarity, package and substitutes.

Assembly Setup

Prepare stencil, SMT/THT sequence and inspection plan.

Inspection and Shipment

Assemble, inspect and support shipment or functional test requirements.

How XFPCB Controls the Build

  • BOM, CPL, Gerber files and assembly drawings are reviewed together before the build.
  • Component package, polarity, rotation and DNP information are checked before placement.
  • Stencil, SMT, THT and mixed-technology sequence are prepared according to the board design.
  • AOI, visual inspection, X-ray or functional test support can be added when required.

SMT PCB Assembly FAQs

What should I send to quote SMT PCB Assembly?

Send Gerber files, NC drill files, board outline, stackup notes, material, copper weight, surface finish, quantity and target lead time. For PCBA or assembly-related work, also send the BOM with manufacturer part numbers, pick-and-place data, assembly drawing, DNP notes and test expectations.

Can XFPCB review the files before production?

Yes. XFPCB can review manufacturability and quotation details before production starts. We check material choices, via structures, component package data, tolerance requirements and inspection requirements before release.

Can XFPCB support both prototype and production orders?

In most cases XFPCB can support both stages. Prototype builds help validate the design, while production planning controls repeatability, documentation, component supply and cost for future orders.

How can I reduce quotation delays?

Provide complete files, expected annual or batch quantity, destination country, special standards, inspection needs and the target schedule. If the design is still changing, tell us which details are fixed and which are under review.

Request a Quote for SMT PCB Assembly

Send your project information to XFPCB and our team will review the key manufacturing or assembly details. A complete RFQ helps us respond with a more accurate quote and a clearer production plan.

  • For bare PCB projects, include Gerber, drill, stackup, material, copper, finish, quantity and lead time.
  • For PCBA projects, include BOM, pick-and-place file, assembly drawing, test notes and approved alternatives.
  • For application-specific projects, share operating environment, reliability expectations and packaging needs.
