Custom OEM PCBA Service with PCB Design and SMT Assembly

Custom OEM PCBA Service

MCPCBA provides custom OEM PCBA services covering PCB design, component sourcing, SMT assembly, DIP assembly and functional testing.

The service supports projects from prototype development to mass production. Customers can provide a product concept, schematic, Gerber files, BOM or complete design package, depending on the project stage.

PCB Design and DFM Review

The engineering team supports schematic design, PCB layout and design-for-manufacturing review.

DFM review can identify potential manufacturing issues before production, including component placement, PCB layout, assembly process and manufacturability. Design optimization can also help reduce production problems and unnecessary manufacturing costs.

PCB Manufacturing

The OEM PCBA service supports PCB manufacturing using FR-4, High-Tg FR-4 and aluminum substrates.

PCB designs can range from simple single-layer boards to multilayer boards. The current manufacturing capability supports up to 20 PCB layers, with board thickness and copper weight customized according to project requirements.

Precision SMT Assembly

The SMT assembly service supports small and fine-pitch electronic components, including 01005, 0201, QFP, BGA and QFN packages.

Automated SMT placement is used for high-density PCB assemblies and double-sided boards. Assembly parameters can be adjusted according to the PCB design and component package requirements.

DIP and Mixed Technology Assembly

For boards containing connectors, terminals, relays, transformers and other through-hole components, DIP assembly can be combined with SMT production.

Manual, selective and wave soldering processes are available for different board structures and production requirements.

Component Sourcing

MCPCBA provides component procurement as part of the OEM PCBA service.

The sourcing team can handle BOM purchasing, component verification and supply coordination. Original components and suitable alternatives can be evaluated according to availability, specifications and project requirements.

PCB Assembly Testing

Testing is integrated into the PCBA manufacturing process to verify assembly quality and board functionality.

Available inspection and testing methods include AOI, X-Ray, ICT, FCT and burn-in testing.

The appropriate combination of inspection and functional testing can be selected according to the product and application.

OEM and ODM Manufacturing

OEM manufacturing allows customers to provide their own product design and production requirements for manufacturing.

For ODM projects, MCPCBA can also participate in the electronic design and development process, including schematic design, PCB layout, DFM optimization and manufacturing preparation.

This makes the service suitable for both established products and new electronic product development.

IP Protection and NDA

Customer design files and product information can be protected through NDA agreements.

The service is designed for projects where schematic files, Gerber data, BOM information, firmware requirements and other technical documents need controlled access during development and production.

Prototype PCBA Manufacturing

Prototype production can start from one piece, allowing engineering teams to verify PCB design and assembly before moving to larger production quantities.

Prototype assembly typically takes 3–5 working days, depending on board complexity and component availability.

Mass Production

After prototype validation, the same manufacturing process can be scaled to small-batch and mass production.

Production planning, component procurement, SMT and DIP assembly, inspection and functional testing can be managed as part of the same OEM PCBA project.
