Reliable PCB Assembly Services from Prototype to Mass Production
LinkPCBA provides professional PCBA assembly services covering SMT, THT, and mixed-technology assembly for global OEM and ODM customers.
Our PCBA assembly capability is built around controlled process execution, stable yield performance, and engineering-driven manufacturing, supporting projects from early prototypes through NPI and long-term volume production.
What PCBA Assembly Means at LinkPCBA

At LinkPCBA, PCBA assembly is not treated as a single manufacturing step.
It is a coordinated execution process that integrates component placement, soldering, inspection, and quality control into a repeatable and scalable workflow.
Our focus is not on claiming extreme theoretical limits, but on ensuring that assembled boards remain consistent, reliable, and manufacturable across production cycles.
PCBA Assembly Scope
Our PCBA assembly services cover a wide range of board types and assembly requirements, including:
- SMT (Surface Mount Technology) assembly
- THT / Through-hole assembly
- Mixed-technology PCBA
- Single-sided and double-sided assemblies
- Fine-pitch components, QFN, BGA, and high-density layouts
Assembly methods are selected based on design requirements, component characteristics, and production stage, rather than a one-size-fits-all approach.

Assembly Process Execution & Control

PCBA assembly at LinkPCBA follows a structured execution framework designed to reduce variation and improve yield stability:
- Engineering review prior to assembly release
- Controlled solder paste printing and placement processes
- Profile-verified reflow and soldering control
- Defined inspection checkpoints during assembly
Key process parameters are monitored and adjusted to ensure repeatability between prototype builds and volume production, minimizing rework and quality drift.
Quality & Inspection Integration
Quality assurance is embedded directly into the PCBA assembly process, including:
- Automated Optical Inspection (AOI)
- X-ray inspection for hidden solder joints
- First Article Inspection (FAI)
- Visual inspection at critical stages
Inspection coverage is designed to support early defect detection and process feedback, rather than end-of-line screening only.
(Detailed inspection capability is available on the Testing & Inspection page.)

From Prototype to Mass Production

LinkPCBA supports PCBA assembly across the full production lifecycle:
- Prototype Builds – Fast validation with engineering support
- NPI & Pilot Runs – Process tuning and yield stabilization
- Mass Production – Consistent execution with controlled quality metrics
Manufacturing data and process learnings are carried forward between stages to ensure a smooth and predictable transition to volume production.
Why Choose LinkPCBA for PCBA Assembly

Customers choose LinkPCBA for PCBA assembly because we offer:
- Engineering-driven assembly execution
- Stable quality and yield performance
- Clear process control and traceability
- Seamless transition from prototype to mass production
- Close integration with PCB manufacturing and downstream processes
We operate as a long-term PCBA manufacturing partner, not a short-term assembly supplier.
