Professional Electronic Design & OEM Customization

Modern electronic products are no longer simple PCB assemblies.
They are complete systems — combining high-density PCBs, complex BOMs, precision mechanical parts, cables & harnesses, firmware integration, and strict reliability requirements.

Many OEM customers struggle not with design, but with execution:

• Multiple suppliers that don’t coordinate

• Component shortages and substitutions without engineering validation

• Assembly issues discovered too late in the process

• Inconsistent quality across pilot runs and mass production

This is where China 365PCB makes the difference.

At China 365PCB, we specialize in high-difficulty turnkey electronic manufacturing, handling everything from BOM sourcing to final box-build assembly under one controlled manufacturing system.

Our capabilities are designed for complex products:

• Multi-layer, HDI, impedance-controlled PCB fabrication

• Full PCB assembly (SMT, THT, mixed technology)

• Cable & wire harness assembly

• Mechanical integration and box-build assembly

• Firmware loading, functional testing, and final inspection

Engineering-Driven Turnkey Manufacturing

Every turnkey project starts with engineering review, not purchasing.
Our teams validate:

• PCB manufacturability and assembly risks

• BOM availability, lifecycle status, and alternates

• Thermal, power, and signal integrity considerations

• Assembly sequence and test coverage

Potential issues are identified before production, not after failures.

Integrated Supply Chain = Lower Risk

With our China 365PCB Online Electronic Component Platform, procurement is fully integrated with manufacturing:

• 100% genuine, traceable components

• Real-time BOM matching and inventory visibility

• Controlled material flow from sourcing to shipment

• Dedicated incoming inspection and lot traceability

By managing both materials and manufacturing internally, we eliminate handoff risks, reduce lead times, and ensure consistency from prototype to mass production.

Built for Complex Products, Not Simple Jobs

China 365PCB is not focused on low-complexity, price-driven assembly.
We are built for customers who need:

• High reliability

• Stable mass production

• Clear engineering communication

• Predictable delivery for complex electronic systems

China 365PCB is not just a contract manufacturer — we are your manufacturing and engineering partner for high-complexity electronic products.

Q1. What does box build assembly include?

Box build assembly includes PCB assembly, cable installation, mechanical assembly, enclosure integration, and system testing.

Q2. Can you support low-volume system builds?

Yes. We support low-volume and pilot builds, as well as full-scale production.

Q3. Do you provide functional testing?

Functional testing can be performed based on customer-defined test procedures or jointly developed test plans.

Q4. How do you manage complex assemblies?

We use process documentation, quality checkpoints, and experienced assembly teams to manage complex system builds.

Q5. Can you ship complete systems globally?

Yes. We support global logistics and export shipments for fully assembled systems.
