Why Choose China 365PCB for Your PCB Assembly Projects?

PCB assembly projects often fail not because of design, but due to poor component sourcing, assembly defects, weak process control, and lack of engineering support. Customers frequently face issues such as misaligned components, inconsistent soldering quality, long lead times, and suppliers who cannot handle complex BOMs or quick-turn requirements.

 

At China 365PCB, we provide end-to-end PCB assembly services backed by real manufacturing capability. From component sourcing and BOM verification to SMT, THT, BGA, and final testing, every step is strictly controlled by experienced engineers. We identify assembly risks early, verify components before production, and ensure stable, repeatable quality.

 

With fast turnaround, full inspection, and clear communication, we help customers reduce assembly failures, shorten delivery cycles, and bring products to market faster.

China 365PCB is not just your PCBA supplier — we are your reliable manufacturing partner.

 

PCB Assembly FAQ

Q1. What types of PCB assembly services do you provide?

 

We provide SMT assembly, through-hole assembly, mixed technology assembly, and prototype to mass production PCBA services, all under one roof.

 

Q2. Can you support turnkey PCB assembly?

 

Yes. We offer full turnkey PCB assembly, including PCB fabrication, component sourcing, assembly, testing, and final inspection. Partial turnkey and consigned assembly are also supported.

 

Q3. What files are required for PCB assembly?

 

To start PCB assembly, we require BOM, pick-and-place files, assembly drawings, and Gerber files. Our engineering team performs a DFM/DFA review before production.

 

Q4. What is your MOQ for PCB assembly?

 

We support low-volume prototype assembly (as low as 1–5 boards) and can scale smoothly to batch and mass production.

 

Q5. What inspection and testing do you perform?

 

Depending on project requirements, we provide AOI, X-ray inspection, ICT, functional testing, and visual inspection to ensure assembly quality.

 

Q6. How do you handle component sourcing risks?

 

Our supply chain team sources components from authorized distributors and trusted suppliers, and provides alternative part recommendations when shortages occur.

Flexible Printed Circuit Boards (Flexible PCBs, Flex PCBs, or FPCs) are transforming modern electronics by replacing bulky rigid boards and wiring harnesses with lightweight, ultra-thin, and highly bendable circuits.

 

Our custom flexible PCBs deliver exceptional design freedom, superior reliability, and significant space and weight savings — making them the preferred choice for compact, dynamic, and high-performance applications.

 

Whether you need single-layer flex circuits for simple wearable sensors or complex multilayer rigid-flex boards for advanced medical or automotive systems, we provide end-to-end support from DFM-optimized design through rapid prototyping to volume production and full PCBA assembly.

 

Typical Specifications of 365PCB's Flexible PCB Boards

We manufacture to IPC-6013 Class 2/3 standards with the following capabilities:

Base Materials: High-performance polyimide (PI) or polyester (PET), thickness 12–125 µm

 

Layer Count: 1–8+ layers, including multilayer flex and rigid-flex constructions

 

Minimum Trace/Space: 50 µm / 50 µm (fine-line capability)

 

Copper Thickness: 0.5 oz to 2 oz (rolled annealed copper recommended for dynamic flex areas)

 

Surface Finishes: ENIG, Immersion Tin, OSP, Selective Carbon Ink, Hard Gold

 

Additional Options: Coverlay, polyimide/FR4/stainless steel stiffeners, EMI shielding, impedance control, blind/buried vias, PSA adhesive, laser profiling

 

Design Tip: For dynamic flex zones, maintain a bend radius of at least 20× the total board thickness. In static applications, 6–10× is often sufficient. We provide free DFM review to optimize your design for yield and reliability.

 

Why Choose Our Flexible PCBs?

 

Ultra-Light & Ultra-Thin Profile — Boards as thin as 0.05 mm and up to 70% lighter than traditional rigid PCBs, perfect for portable, wearable, and space-constrained devices.

 

High-Density Circuitry — Minimum trace width/spacing down to 50 µm / 50 µm, enabling complex designs without increasing footprint or adding connectors.

 

Dynamic & Static Flexibility — Engineered to withstand repeated bending, folding, and 3D shaping. Ideal for moving parts, sliding mechanisms, or foldable products.

 

Proven Durability — Excellent resistance to vibration, shock, and extreme temperatures (-40°C to +150°C+). Fewer solder joints mean higher long-term reliability.

 

Superior Thermal Performance — Polyimide base material provides efficient heat dissipation, critical for high-power or dense components.

 

Excellent Solderability & Assembly Compatibility — Multiple surface finishes ensure strong, defect-free SMT assembly and long-term stability.

 

Compared to rigid PCBs and traditional wiring, flexible circuits can reduce overall assembly weight by over 60%, eliminate bulky connectors, and dramatically improve signal integrity in compact layouts
