Prototype Assembly
Small-batch prototype PCB assembly built to your Gerber files and BOM, using SMT, THT, or mixed technologies for design validation, debugging, and faster engineering iteration.
Accelerate your product development with one-stop PCBA prototype services that move seamlessly from bare PCB fabrication to component sourcing, SMT/THT assembly, inspection, testing, and coating. FX PCB helps startups, engineers, and product teams validate designs faster, reduce rework with free DFM analysis, and build reliable prototype assemblies ready for debugging, field trials, or production planning.

End-to-end prototype support from PCB fabrication and sourcing to assembly, testing, coating, and production scaling.
Small-batch prototype PCB assembly built to your Gerber files and BOM, using SMT, THT, or mixed technologies for design validation, debugging, and faster engineering iteration.
Custom bare board fabrication for rigid, metal-based, high-frequency, ceramic, glass, and rigid-flex designs, with ISO 9001 processes and surface finishes including ENIG, immersion silver, tin, and OSP.
Experienced procurement support with access to over 600k local stock, bulk buying advantages, alternative part suggestions, and customer-approved substitutions to reduce cost, shortages, and lead times.
A complete one-vendor solution covering procurement, SMT/THT assembly, programming, testing, and final inspection, helping teams avoid supplier coordination and move from prototype to production smoothly.
Custom PCBA functional testing using electrical checks, performance verification, test jigs, and customer-specific procedures to confirm each assembly meets intended operating requirements.
Protective conformal and Parylene coating services for waterproof, moisture-proof, salt fog, acid, alkali, and harsh-environment resistance in demanding commercial, medical, and industrial applications.

Experienced specialists supporting complex PCB and PCBA programs.
FX PCB has built its reputation over more than 15 years in PCB and PCBA manufacturing, growing from a printed circuit board manufacturer into a comprehensive electronics manufacturing partner. With dedicated PCB and PCBA facilities in Shenzhen and a US office in Plano, Texas, the company supports global brands, startups, and engineering teams across consumer electronics, automotive, medical devices, industrial automation, telecommunications, aerospace, and defense. Its mission is to act as a catalyst for customer success by delivering reliable, standards-driven assemblies that meet demanding performance, compliance, and value expectations. The team emphasizes uncompromising quality, speed to market, collaborative partnership, environmental responsibility, and continuous innovation.
PCBA prototype services turn your electronic design files into a small batch of assembled circuit boards for validation. FX PCB can support bare PCB fabrication, component sourcing, SMT and through-hole assembly, inspection, testing, and coating. The goal is to help you verify form, fit, function, and manufacturability before committing to low-volume or mass production.
