Professional PCB Assembly Services for Quality Manufacturing

PCB assembly service, often called PCBA, is the process of mounting electronic components onto a bare printed circuit board to create a functional electronic assembly. It can include SMT placement, through-hole insertion, soldering, inspection, programming, conformal coating, and functional testing. FX PCB also supports turnkey assembly, where sourcing, assembly, quality control, and production support are managed together.

The assembly layer in PCB design is a documentation layer that helps manufacturers understand where components should be placed and how the board should be assembled. It often includes component outlines, reference designators, polarity markings, orientation details, and mechanical notes. This layer supports accurate SMT and THT assembly and helps reduce placement errors during manufacturing.

PCB assembly can include design file review, DFM analysis, component sourcing, solder paste printing, SMT placement, through-hole insertion, reflow or wave soldering, manual assembly, inspection, programming, cleaning, coating, and testing. Depending on the project, FX PCB can also provide functional test fixtures, Parylene or conformal coating, storage, and scaling support from prototype to production.

Turnaround depends on board complexity, component availability, quantity, testing requirements, and finishing needs. FX PCB’s standard delivery window is often 1–2 weeks, and prototype boards may be assembled from 24 hours once all parts are available. Quick-turn and express options are available for urgent schedules, although expedited shipping or production may add cost.

Yes. FX PCB offers component sourcing and procurement support through an experienced sourcing team with access to over 600k local stock. The team can help reduce cost, shorten lead times, and manage shortage risks. If a substitute component is recommended, FX PCB requires customer approval before using it in your assembly.

FX PCB operates with ISO9001, ISO14001, and ISO13485 certified facilities and follows IPC-A-610 Class 2/3 workmanship standards for assembled boards. Quality controls can include AOI inspection, X-ray inspection, functional testing, and 100% electrical testing on bare PCBs. RoHS, REACH, and UL-related compliance support also helps products meet global market requirements.

Yes. FX PCB supports the full path from early prototypes to low-volume builds and high-volume production. Prototype assembly helps engineers validate designs quickly, while turnkey and production assembly provide sourcing, repeatable manufacturing, testing, and inspection. This allows customers to scale without changing suppliers as requirements grow.

A complete quote usually requires Gerber files, a bill of materials, pick-and-place or centroid data, assembly drawings, testing requirements, quantity, preferred lead time, and any special notes such as coating, programming, or packaging. Clear documentation helps FX PCB provide accurate pricing, identify manufacturability issues, and prevent delays during production.
