PCBA Manufacturing Process
Our Proven Manufacturing Process - Quality at Every Step
1. Solder Paste Printing
High-precision stencil printing deposits the exact amount of solder paste onto each pad. Calibrate for optimal paste height and coverage to ensure consistent soldering.
2. Component Placement
Advanced pick-and-place machines position components with ±99% accuracy. Operators verify critical placements before the next stage.
3. Reflow Soldering
Boards pass through a controlled temperature reflow oven with multiple heating zones. We monitor thermal profiles to prevent damage and ensure strong, reliable solder joints.
4. Board Cleaning
Automated cleaning removes excess solder flux, leaving boards pristine and eliminating potential corrosion or short-circuit risks.
5. Quality Inspection & Testing
Multi-level inspection includes SPI, AOI, X-ray (for BGA), and full functional testing. We verify 100% of assemblies meet IPC-A-610 standards.
6. Manual Touch-Up
Our skilled technicians perform rework on any boards requiring manual correction, maintaining consistency with production standards.
7. Functional Testing
Custom test programs exercise all board functions under real-world conditions. Only boards passing 100% testing proceed to packaging.
8. Packaging & Delivery
PCBA Boards are carefully packaged in static-safe materials and prepared for shipment according to your specifications.

F.A.Q.
We accept orders starting from 1-piece prototypes. There’s no strict MOQ, though volume orders typically receive better pricing. Contact us to discuss your specific project
Yes. We provide full turnkey PCBA services including BOM sourcing, PCB fabrication, SMT/THT assembly, and functional testing — all under one roof. You only need to provide your Gerber files, BOM, and assembly drawings.
We treat customer design files and product information as confidential.
Upon request, we support NDAs and internal access control to ensure your intellectual property is protected throughout the PCBA process.
We apply the same manufacturing standards, inspection steps, and process controls to both small and large batches. This includes incoming material inspection, SPI, AOI, X-ray (for BGA/QFN), and functional testing where required, ensuring batch-to-batch consistency rather than sample-only quality.
We offer flexible sourcing options. You may provide a full or partial BOM, or request turnkey PCBA with component sourcing handled by us.
Our supply chain focuses on traceable components, stable vendors, and risk control for shortages or substitutions, with all changes communicated for approval before production.
We source components from authorized distributors or verified suppliers, supported by incoming inspection and traceability records.
For critical components, we implement additional verification steps to reduce the risk of counterfeit or mismatched parts entering the production process.
Depending on your project needs, we support SPI, AOI, X-ray inspection, ICT, and functional testing.
We can work with your test procedures or assist in developing functional test methods to identify issues early and reduce field failures.
Yes. We regularly assemble PCBA with fine-pitch components, BGA, QFN, multi-layer boards, and mixed technology (SMT + THT).
Our process is optimized for complex layouts, controlled soldering profiles, and stable yield on challenging designs.
To prepare an accurate quote, we typically need your PCB files (Gerber), BOM, assembly drawings, target quantity, and any testing or special process requirements.
If information is incomplete, our engineers will clarify details before quoting to avoid hidden costs later.
We work with overseas OEMs, ODMs, engineering teams, and technology-driven companies across industrial, automotive, medical, energy, and communication sectors.
Whether you are developing a new product or scaling an existing one, we adapt our PCBA support to your project stage and complexity.
