What is Partial Turnkey PCB Assembly?
Partial turnkey pcb assembly is a manufacturing model positioned between Turnkey PCB Assembly and pure contract manufacturing.
- The customer may provide some components, bare PCBs, or specialized materials.
- The manufacturer is responsible for sourcing any missing materials, completing assembly, testing, and packaging.
Common models include
- Consigned PCB assembly (consigned material processing): The customer supplies all or part of the components, and the manufacturer handles processing, soldering, testing, and other production steps.
- OEM PCB assembly (original equipment manufacturer): The customer provides the design and certain key materials, and the manufacturer completes the remaining production stages as specified.
This model is particularly suitable for
- Customers with existing inventory or custom parts.
- Projects aiming to accelerate delivery while controlling costs.
- R&D teams requiring confidentiality or in-house quality control for critical components.
Service Process and Highlights
1. Material Handover and Review
Customer provides materials and a bill of materials (BOM) in advance, clearly indicating supplied items and those to be procured.
Engineers review incoming materials for quality and process compatibility (package type, dimensions, storage conditions, etc.).
2. Direct Procurement and Unified Inspection
We establish internal agreements with original manufacturers to source components directly from the factory, ensuring authenticity and traceability. All customer supplied and factory procured materials undergo unified Incoming Quality Control (IQC) inspection, verifying package type, dimensions, and storage conditions to guarantee process compatibility and long term reliability. PCB Manufacturing (if required)
If bare boards are not supplied by the customer, the manufacturer produces them.
3. Assembly and Soldering
High-speed SMT placement, THT insertion, or hybrid processes to balance efficiency and precision.
4. Testing and Quality Control
Comprehensive inspection including AOI, X-ray, ICT, and functional testing.
Each PCBA is assigned a unique traceability code, recording incoming batch details and processing data
5. Packaging and Delivery
Anti-static, moisture-proof, and shock-resistant packaging suitable for both domestic and international shipping.
Core Advantages
- Flexible Division of Labor: Customers can adjust the proportion of supplied materials based on budget and supply chain conditions.
- Cost Control: Utilize existing inventory to reduce duplicate procurement costs.
- Optimized Lead Time: When all materials are ready, production can start immediately, shortening delivery cycles.
- Quality Assurance: Whether through consigned PCB assembly or OEM PCB assembly, the manufacturer applies consistent processes and inspection standards.
- Collaborative Supply Chain: Combines customer resources with manufacturer sourcing channels to reduce single-source dependency risks.
Applicable Scenarios
Board-Level Partial Turnkey PCBA Reference
This smart fragrance device project shows how partial turnkey PCBA support can work when the customer already has the product direction, enclosure concept, and market-side definition in place.
STHL supported the project at the PCBA main board level, focusing on board design and manufacturing support for the electronics inside a portable smart fragrance device. The main board needed to coordinate power, control, LED behavior, fan-related electronics, assembly fit, and testing requirements within limited internal space.
For buyers, this is a typical partial turnkey scenario: the customer keeps control of the product definition, while STHL supports the board-level electronics work through PCBA design, PCB assembly, component sourcing coordination, manufacturability review, and test preparation.
