Turnkey vs Consigned PCB Assembly: Which Is Better?

What Is Turnkey PCB Assembly?

In a turnkey model, the manufacturer manages:


  • PCB fabrication
  • Component sourcing
  • SMT assembly
  • Testing


The customer only provides design files.

Advantages


  • Simplified project management
  • Faster production
  • Reduced sourcing workload
  • Better supplier coordination
  • Potential Drawbacks


Less direct control over component purchasing

Turnkey vs Consigned PCB Assembly

What Is Consigned PCB Assembly?

In a consigned model, the customer supplies all components while the assembler performs manufacturing.

Advantages


  • Full control over component sourcing
  • Suitable for specialized or customer-owned inventory
  • Potential Drawbacks
  • Increased logistics complexity
  • Higher risk of missing components
  • Longer production preparation time


Which Option Is Better?
Turnkey assembly is often ideal for:
  • Startups
  • OEMs
  • Rapid prototyping
  • Small and medium production runs
Consigned assembly may be preferred when:
Components are customer-supplied
Strict supplier requirements exist

Proprietary inventory is involved

For most projects, turnkey PCB assembly offers greater convenience, shorter lead times, and reduced supply chain risks, while consigned assembly remains useful in specialized situations.
