  • Flexible small-quantity orders – 10 to 100 pieces
  • Assembly of both double-sided and multilayer PCBs
  • Support for SMT and/or through-hole components
  • Testing and inspection options

Fast turn services are ideal for verifying PCB designs, market evaluation of new products, and bridging gaps in supply during mass production.

Benefits of Using Fast Turn PCB Assembly

Here are some of the main advantages of utilizing fast turn PCB assembly:

  • Faster time-to-market – Enables rapid prototyping and validation of designs to bring products faster to market
  • Low upfront costs – Minimum order quantities make prototyping affordable for verifying concepts
  • Design flexibility – Ability to test different PCB configurations and component placements with short iteration cycles
  • Efficient supply chain – Fast assembly eliminates bottlenecks when moving from design to testing phases
  • Quality – Reputable manufacturers provide inspection, testing, and quality checks even for fast turn orders
  • Scalability – Seamless transition to mass production with the same manufacturer is enabled

Factors to Consider When Choosing a Fast Turn PCB Assembly Manufacturer

Here are some important factors to evaluate when selecting a suitable fast turn PCB assembly manufacturer:

  • Turnaround time – How quickly can they deliver fully assembled boards?
  • Location – Where are they located? Choosing a local manufacturer saves time and shipping costs.
  • Minimum order quantity – What is their order quantity cut-off for fast turn services?
  • Design constraints – What are their PCB size limits, number of layers, component types etc.
  • Testing and inspection – What validation, testing and quality control steps do they perform?
  • Supply chain – Do they maintain stock of common components for faster assembly?
  • Qualifications – Are they certified to standards such as ISO 9001 for quality systems?
  • Pricing – How do their assembly costs compare? Get quotes from multiple vendors.
  • Production capabilities – Can they seamlessly scale up to mass production volumes?
  • Customer service – Do they provide engineering support and are responsive to inquiries?

Carefully vetting manufacturers on the above parameters will help identify the right partner who can reliably deliver quality boards within your timeframes.

When selecting among the reputable fast turn PCB assembly manufacturers in China, here are some key factors to consider:

Production Capabilities

  • What is their SMT component mounting density and minimum component size handling capability? Higher densities (015mm pitch) and smaller 01005 components offer greater assembly flexibility.
  • Do they support advanced PCB technologies like HDI, flex or rigid-flex boards?
  • What is their maximum PCB size and thickness? Larger boards typically have longer assembly time.
  • How many assembly lines do they have and what is their overall daily capacity? More lines means faster delivery for batches.


  • Are they certified to international quality standards like ISO 9001, UL, IATF 16949 etc?
  • Do they offer inspection using automated optical, x-ray, solder paste inspections?
  • What product validation, testing, and qualification checks are done? Functional testing is highly recommended.

Ordering Process

  • How is the assembly turnaround time calculated? From order placement or documentation/components receipt?
  • What design, BOM, documentation deliverables do they require? Are online submissions available?
  • Do they have an online quotation and order tracking system?
  • How flexible are they on order quantities for prototyping? Lower MOQs allow more design iterations.


  • Is engineering assistance provided for assembly-related issues and DFM feedback?
  • Do they have local sales and customer service support?
  • What supply chain capabilities do they offer for procuring components?
  • Can they provide expedited delivery options at added cost?


  • What is their pricing model? Per component type/quantity, board size, turnaround time?
  • Are volume discounts offered for higher quantities to smooth prototyping to production ramp up?
  • What are the costs for additional testing, inspection, certification services?
  • Are there hidden handling, packaging, insurance charges?


  • How responsive are they in providing quotation and answering pre-sales technical queries?
  • Can they communicate effectively in your preferred language?
  • Do they have a track record of delivering on committed schedule and order quantities?

Carefully evaluating manufacturers against the above criteria will help identify the right partner who can deliver quality fast turn PCB assemblies tailored to your specific prototyping needs.

Frequently Asked Questions

Q: What are some key tips for designing PCBs optimized for fast SMT assembly?

A: Here are some helpful design for assembly guidelines:

  • Allow adequate clearance between components to enable pick and place.
  • Ensure uniform component orientation to ease operator assembly.
  • Limit component height variations across the board.
  • Avoid via-in-pad which requires additional hole filling steps.
  • Choose larger 0402 and 0603 components where possible over 0201 sizes.
  • Minimize BGA fan-out routing complexity.
  • Clearly define component callouts, reference designators, markings.
  • Specify tight component tolerances for critical dimensions like thickness.
  • Spread placement of tall components to avoid localized shadowing.
  • Group components into assembly-friendly blocks.

Q: What documentation do manufacturers need for assembling prototype boards?

A: Typical documents required are:

  • Gerber files of all circuit layers
  • 2D or 3D printed circuit board drawings
  • Bill of materials with component list, reference designators, quantities
  • Approved vendor list if specific component brands are required
  • Assembly drawings indicating location of all components
  • Text file detailing any special assembly instructions
  • Solder paste stencil if required

Q: Can manufacturers procure components needed for prototyping?

A: Many assembly providers can procure components based on the bill of materials and help substitute any hard to source parts. However, providing excess quantities of components upfront allows the fastest assembly. Some manufacturers also maintain stock of popular components used in prototyping.

Q: How are functional testing and inspection handled for fast turn boards?

A: Manufacturers commonly test assembled prototype boards for:

  • Power continuity or open circuits
  • Functional validation if test points are provided
  • ICT testing for shorts, leakage between networks
  • Flying probe testing to verify electrical connectivity
  • AOI inspection of SMT solder joints
  • X-ray inspection of BGA joints

It is best to discuss testing needs upfront so suitable debugging points can be designed-in if needed.

Q: What support is provided for debugging or correcting issues with assembled prototypes?

A: Manufacturers’ engineering teams provide assistance in identifying and resolving any assembly issues found during prototype testing and validation. If certain components need replacement or rework, additional charges may be incurred depending on effort needed. Issuing manufacturing change orders (MCO) for design modifications is also supported.


Fast turn PCB assembly enables companies to accelerate product development by rapidly assembling prototypes for verification within days. It is crucial for startups and engineers needing functional boards quickly to evaluate concepts and gather market feedback.

China offers many leading PCB and assembly manufacturers capable of delivering quality boards within 24 to 72 hours, ideal for low-quantity orders. When selecting among these reputable vendors, factors like production capabilities, quality, order process ease, customer support, pricing, and communication channels should be evaluated to identify the right partner matching needs.

By leveraging fast turn assembly combined with disciplined prototyping, products with strong market fit can be designed faster and brought to production more efficiently.
