Turnkey PCBA Manufacturing and One-Stop PCB Assembly Service

Turnkey PCBA Manufacturing

Turnkey PCBA manufacturing provides a complete production process from PCB fabrication and component sourcing to PCB assembly, testing and finished product delivery.

Customers can provide Gerber files and BOM data, while the manufacturing process covers PCB production, component procurement, SMT and DIP assembly, inspection, functional testing and final assembly.

The service supports prototype development, small-batch production and volume manufacturing for different electronic products.

Key Features

• One-stop turnkey PCBA manufacturing

• PCB fabrication and PCB assembly

• Full BOM component sourcing

• SMT and DIP/THT assembly

• BGA and QFN assembly capability

• AOI and X-Ray inspection

• ICT and FCT testing

• Burn-in testing when required

• Box build and final product assembly

• Prototype to mass production

• Engineering and DFM support

PCB Fabrication

PCB fabrication is integrated into the turnkey production process. The available PCB capability supports 1 to 32 layer boards, including rigid, HDI, flexible and metal-core PCB options.

Material options include FR-4, High-TG FR-4, aluminum and Rogers/PTFE. Copper thickness can range from 0.5oz to 6oz depending on the board design.

Available surface finishes include ENIG, HASL, lead-free HASL, OSP, immersion silver and immersion tin.

Component Sourcing

The turnkey service includes BOM procurement, component kitting and supply management.

Components can be sourced according to the customer's approved BOM, with support for component substitution and obsolete part management when required.

This allows PCB fabrication, component purchasing and assembly to be coordinated within the same production workflow.

SMT Assembly

SMT assembly supports compact components including 0201, BGA and QFN packages.

The assembly process is suitable for high-density electronic boards where accurate component placement and controlled soldering are required.

DIP and THT Assembly

Through-hole components can be assembled using DIP/THT processes together with SMT production.

Wave soldering and other suitable soldering processes can be selected according to the board structure and component requirements.

SMT and DIP can therefore be combined for mixed-technology PCB assemblies.

PCB Assembly Testing

Testing and inspection can be selected according to the product design and quality requirements.

Available methods include:

• AOI inspection

• X-Ray inspection

• ICT testing

• FCT functional testing

• Flying probe testing

• Burn-in testing

X-Ray inspection can be used for applications involving BGA and other hidden solder joints.

Box Build and Final Assembly

The service can extend beyond PCBA production to box-build assembly and final product preparation.

Depending on the project, the manufacturing process can include final assembly, packaging and logistics after the assembled PCB has passed the required inspections and tests.

Prototype to Mass Production

The turnkey PCBA service supports different production stages, from prototype quantities and small-batch orders to mass production.

Prototype production allows customers to verify the PCB design and assembly before moving into larger production quantities. Once the design is approved, production can be scaled according to the required volume.

Engineering and DFM Support

Engineering support is available before production to review Gerber files, BOM information and manufacturing requirements.

DFM review can identify potential PCB fabrication and assembly issues before production begins, helping reduce manufacturing problems during the transition from design to physical boards.
