Gerber & BOM • Fast Costing • Engineering Review Included
What Is Turnkey PCB Assembly?
Turnkey PCB Assembly (also referred to as turnkey PCB manufacturing or turnkey PCB assembly service) means that the PCB manufacturer takes full responsibility for the entire PCBA process, including:
- PCB fabrication
- Electronic component procurement
- SMT and THT assembly
- Quality inspection and testing
- Final delivery
Instead of coordinating multiple vendors, customers work with one single partner, significantly reducing communication risks and project delays.
Comprehensive Turnkey Solutions
We handle the entire lifecycle of your board assembly so you can focus on product development.
PCB Fabrication: Rigid, Flex, and Rigid-Flex boards.
Component Sourcing: Full BOM procurement with transparent pricing.
Assembly: SMT (Surface Mount), THT (Through-Hole), and Mixed Technology.
Advanced Capabilities: Capable of handling 0201 passives, fine-pitch BGAs (0.4mm pitch), QFNs, and CSPs.
Full Turnkey vs Partial Turnkey PCB Assembly
Full Turnkey PCB Assembly
In a full turnkey PCB assembly, Sayfu manages the complete process:
- PCB fabrication based on approved Gerber files
- BOM analysis, costing, and component sourcing
- Approved alternative component management (when required)
- SMT & THT assembly and functional testing
This option is ideal for prototype, low-volume, and early-stage production, where speed, cost control, and engineering support are critical.
Partial Turnkey Assembly
For partial turnkey assembly, customers may supply:
- Bare PCBs, and/or
- Selected or customer-specified components
Sayfu will handle the remaining materials, assembly, inspection, and testing. All customer-supplied components are subject to incoming quality control (IQC) to ensure assembly reliability.
Advantages of Full Turnkey PCB Assembly Services
Shorter Lead Time & Faster Quotation
PCB assembly typically involves three key phases: PCB fabrication, component procurement, and assembly. Managing these steps separately often leads to extended lead times and communication gaps.
With Sayfu’s full turnkey assembly, you can:
- Upload Gerber and BOM files once
- Receive consolidated pricing for PCB, components, and assembly
- Benefit from streamlined engineering review and faster production start
This integrated approach enables quicker time-to-market for both prototype and low-volume PCB assembly projects.
Approved Alternatives • Supply Chain Risk Check
Lower Overall Manufacturing Cost
In most prototype and low-volume projects, full turnkey PCB assembly can reduce total cost by:
- Eliminating multiple freight and handling charges
- Leveraging Sayfu’s long-term relationships with authorized component distributors
- Reducing procurement and inventory management overhead
Our procurement team sources components based on availability, lifecycle status, and cost efficiency, helping customers mitigate supply chain risks.
One Vendor to Manage
Turnkey PCB manufacturing allows customers to work with a single point of contact throughout the entire project lifecycle.
This significantly reduces:
- Miscommunication between PCB fabrication and assembly stages
- Schedule conflicts and delivery delays
- Engineering change management issues
Sayfu coordinates all manufacturing steps internally, ensuring consistency and accountability.
Integrated Shipping, Inventory & Assembly Support
As part of our turnkey PCB assembly service, Sayfu offers:
- Final product assembly and packaging
- Inventory coordination for components and finished boards
- Direct shipment from manufacturing facility to customer
For customers with advanced supply chain requirements, API-based integration with ERP or ordering systems may be supported upon request.
Engineering & Quality Control in Turnkey PCB Assembly
Engineering Review & BOM Management
Before production, our engineering team performs:
- Gerber and fabrication data review
- BOM validation and risk analysis
- DFM and DFT checks
- Technical queries (TQ) communication when clarification is required
Approved component substitutions are managed transparently to maintain design intent and reliability.
Assembly Process & Quality Assurance
Sayfu applies strict quality control throughout the turnkey assembly process:
- Incoming quality inspection (IQC) for all components
- SMT and THT process control
- AOI, X-ray inspection, and functional testing (as required)
- Final quality inspection prior to shipment
