Why Most OEM Companies Still Need China in a China Plus One Strategy


Many OEM companies are actively exploring the China Plus One Strategy as global supply chain risks increase, labor costs shift, and geopolitical uncertainty affects long-term manufacturing planning.

China Plus One Strategy

However, in real-world electronics manufacturing, the Plus One Strategy rarely replaces China. Instead, it restructures how global production is distributed.

This article explains why China still plays a critical role in most OEM supply chains, especially in PCBA and industrial electronics manufacturing.


What Is a China Plus One Strategy?

The China Plus One Strategy is a global sourcing model where companies maintain manufacturing in China while establishing an additional production base in countries such as Vietnam, Mexico, India, or Eastern Europe.

The purpose is not replacement, but diversification of manufacturing risk.

In practice, most companies implementing a China Plus One Strategy still rely on China for:

  • PCB assembly (PCBA)
  • Electronic components sourcing
  • Engineering support
  • Supply chain coordination

Myth #1: China Plus One Strategy Does Not Mean Leaving China

A common misunderstanding is that the China Plus One Strategy is a relocation strategy.

In reality, most OEM companies adopt a hybrid manufacturing structure:

  • China remains the core production and engineering hub
  • Secondary countries handle assembly or regional final integration
  • Critical components and PCBA processes stay China-dependent

Even companies with mature global diversification models still rely on China for stability and scalability.


Myth #2: Manufacturing Can Move, but Supply Chain Cannot

One of the biggest underestimated challenges in the China Plus One Strategy is supply chain fragmentation.

A typical OEM electronic product includes multiple interconnected layers:

  • PCB fabrication and assembly
  • Semiconductor components
  • Passive components (resistors, capacitors, inductors)
  • Mechanical structures
  • Firmware and testing systems

While assembly can be relocated, upstream supply chains remain highly concentrated in China due to:

  • Supplier density
  • Fast component availability
  • Short iteration cycles

Myth #3: Engineering Support Is Harder to Move Than Production

Many companies assume manufacturing relocation is primarily a logistics decision.

However, engineering capability is often the most difficult element to replicate outside China.

Critical engineering functions include:

  • DFM (Design for Manufacturing) optimization
  • NPI (New Product Introduction) support
  • SMT process tuning
  • PCB test fixture development
  • Quality engineering and yield improvement

A successful China Plus One Strategy requires rebuilding this engineering layer, not just moving assembly lines.

Why China Still Dominates Electronics Manufacturing

Despite global diversification strategies, China remains central due to structural advantages:

1. Integrated Component Ecosystem

China provides the fastest access to a dense and complete electronic component supply chain.

2. High-Density PCBA Manufacturing Base

China hosts the largest SMT and PCB assembly capacity globally.

3. Manufacturing-Oriented Engineering Talent

Engineering expertise focused on production efficiency and yield improvement is widely available.

4. End-to-End Supply Chain Integration

From PCB fabrication to final assembly, processes are tightly connected.

When the China Plus One Strategy Actually Works

A China Plus One Strategy is effective when driven by real operational needs rather than trend-based decisions:

  • Customer or regulatory regional requirements
  • Tariff optimization strategies
  • Supply chain risk mitigation
  • Localized final assembly requirements
  • Market proximity considerations

In these cases, diversification complements China rather than replacing it.


Practical Model: Hybrid Manufacturing Strategy

Most successful OEM companies follow a phased approach:

Stage 1: China-Centered Development

  • Prototype production
  • Engineering validation
  • NPI cycles (EVT / DVT / PVT)

Stage 2: Dual-Region Production

  • China handles PCBA and engineering-intensive manufacturing
  • Secondary regions handle assembly or localization

Stage 3: Hybrid Global Manufacturing

  • Multi-region production balance
  • Risk distribution across supply chains
  • Capacity optimization based on demand

This structure ensures operational stability under a China Plus One Strategy.


Real-World Constraints OEM Companies Face

Even when companies plan diversification, they often encounter practical constraints:

  • Component sourcing still centralized in China
  • Engineering feedback loops slower outside China
  • Quality consistency harder to maintain cross-region
  • Higher hidden costs in duplicated supply chains

Key Questions Before Implementing a China Plus One Strategy

OEM companies should carefully evaluate:

  • Which parts of the manufacturing process can realistically relocate?
  • How will engineering and NPI support be maintained?
  • What happens to test fixtures and validation systems?
  • Can quality consistency be maintained across regions?
  • What is the true total cost including engineering overhead?

Conclusion

For most OEM companies, the China Plus One Strategy is not a replacement model but a structural diversification approach.

China remains essential due to its unmatched electronics manufacturing ecosystem, particularly in PCBA production, engineering support, and supply chain integration.

A realistic global manufacturing strategy focuses on balancing resilience with capability rather than attempting full relocation.
