China PCBA Contract Manufacturing & Assembly Services

FX PCB’s contract manufacturing service can include bare PCB fabrication, component sourcing, SMT placement, through-hole assembly, mixed-technology assembly, soldering, programming, inspection, functional testing, and optional protective coating. The exact scope is matched to your Gerber files, BOM, drawings, test requirements, and production volume, so you can use one manufacturing partner from prototype through mass production.

Prototype timing depends mainly on board complexity, component availability, and test requirements. FX PCB supports fast-turnaround prototyping and can assemble boards from 24 hours once all parts are available. Standard PCBA delivery is commonly 1–2 weeks, with expedited options possible for urgent projects, especially when components are already sourced or available locally.

Yes. FX PCB provides SMT, through-hole, and mixed SMT plus THT assembly for modern circuit boards that use both surface-mount and leaded components. Production methods may include automated high-speed placement, manual assembly for small batches, reflow soldering, wave soldering, and specialized forming equipment for components that require custom preparation before insertion.

Yes. FX PCB offers intelligent component sourcing through an experienced procurement team with access to over 600k local stock options. The team can help reduce lead times, manage shortages, compare pricing, and recommend approved alternatives. Replacement components are not used without customer approval, helping maintain design intent while controlling cost and supply chain risk.

FX PCB operates with certified and compliance-driven quality systems, including ISO9001, ISO14001, ISO13485, IPC-A-610 Class 2/3 standards, RoHS Compliance, REACH Compliance, and UL-related controls. Inspections may include AOI, X-ray, electrical testing, and functional testing depending on the build. Bare boards receive 100% electrical testing before assembly.

For an accurate quote, provide Gerber files, BOM, pick-and-place files, assembly drawings, PCB specifications, quantity, test requirements, and any special instructions such as programming, conformal coating, or packaging. Clear manufacturer part numbers and approved alternates help speed procurement. FX PCB can also complete DFM review to flag potential production issues early.

Yes. FX PCB supports prototype, low-volume, and high-volume PCBA manufacturing, allowing customers to scale without changing suppliers. This is useful for startups, pilot programs, and specialized electronics that need professional assembly without large initial commitments. As demand grows, the same manufacturing partner can support repeat builds, procurement planning, and production process consistency.

Yes. FX PCB provides PCBA coating services including conformal coating and advanced Parylene nano-vacuum coating. These coatings help protect assemblies from moisture, salt fog, acids, alkalis, and harsh operating environments. Parylene options can provide ultra-thin, uniform protection suitable for demanding commercial, industrial, medical, and high-reliability applications where environmental resistance is important.
