Leader Global Electronics is a Taiwan-based PCB assembly and EMS manufacturer supporting OEM customers worldwide.
We provide SMT, THT (DIP), testing, and turnkey manufacturing services—from prototype (NPI) builds through scalable production.
Our ISO 9001-certified facility is equipped with advanced SMT production lines, high-speed pick-and-place systems, automated solder paste printing equipment, and lead-free reflow ovens, enabling support for complex PCB assemblies including BGA, QFN, LGA, and fine-pitch components.
To ensure manufacturing consistency and product quality, we implement AOI, X-ray inspection, ICT, and functional testing throughout the production process—from prototype validation through volume production.
Before quotation and production planning, our engineering team reviews PCB design data and BOM information to evaluate manufacturability, component availability, lead-time exposure, and potential production risks.
This engineering-driven approach helps identify issues earlier, improve production readiness, reduce sourcing risks, and support more stable manufacturing outcomes.
👉 Have a PCB project in development?
Share your BOM, Gerber files, or project requirements with our team for engineering review and quotation support.
Our Taiwan PCB assembly facility is equipped with advanced SMT production lines and automated systems designed to support both high-mix and scalable production.
We support:
Fine-pitch components (BGA, QFN, LGA)
High-density and complex PCB designs
Prototype (NPI) to volume production
Turnkey and consigned manufacturing models
This means we don’t just assemble boards — we help ensure they are manufacturable, stable, and ready for scaling.
Reducing costs and minimizing unexpected production risks — before production starts.
Have a design ready? Send us your BOM or Gerber files — we’ll review it and help you move forward with confidence before production.
Our engineering team will provide actionable feedback, including manufacturability insights, cost optimization suggestions, and component risk evaluation.
Many OEM customers work with us before finalizing their design to avoid costly redesign and sourcing issues later.
Our production lines are built for precision, consistency, and flexibility—supporting both prototype builds and scalable mass production.
We utilize advanced manufacturing equipment to ensure stable quality and reliable assembly performance:
▪ High-speed SMT pick-and-place machines (01005 capable)
▪ Fully automated solder paste printing with SPC monitoring
▪ Lead-free reflow ovens with precise thermal profiling
▪ THT (DIP) insertion lines and manual soldering stations
👉 We support single-sided and double-sided assembly, including complex mixed-technology PCB builds.
👉 Our manufacturing process is designed to support repeatable quality, stable production yields, and scalable manufacturing from prototype through production.
👉 Advanced process control and equipment capability help support fine-pitch components, complex PCB assemblies, and engineering-focused manufacturing programs.
Inspection & Testing Systems (Quality Control You Can Trust)
To ensure stable quality and reduce field failures, we implement comprehensive inspection and verification processes throughout production:
▪ 100% AOI (Automated Optical Inspection)
Detects soldering defects and placement issues before shipment
▪ X-ray inspection
For BGA, QFN, and hidden solder joints with void ratio analysis
▪ ICT (In-Circuit Testing)
Electrical verification of components and assembly accuracy
▪ FCT (Functional Testing)
Power-on and functional validation based on your specifications
▪ Burn-in testing (optional)
Stress testing under controlled conditions with traceable records
👉 We verify every build — not just assembly, but performance and long-term reliability before shipment.
👉 If you have specific testing requirements, our engineering team can help define and optimize the test strategy before production.
👉 Many issues can be identified and prevented at the testing definition stage — before production begins.
👉 Helping reduce field failures, returns, and post-production risks.
Facility Size & Production Capacity
Our manufacturing facility is designed to support both prototype builds and scalable mass production, ensuring flexibility across different project stages.
▪ Factory area: 28,500 sq. ft.
▪ 5 high-speed SMT production lines
▪ 1 fully equipped THT assembly line
▪ Daily SMT Placement Capacity: Up to 6.2 Million Placements based on R/C components.
▪ PCB Size Support up to 500 mm × 500 mm
👉For boards exceeding this size, please share your BOM or Gerber files — our engineering team will review and evaluate feasibility.
We support both low-volume prototype builds and high-volume mass production — with a smooth transition from NPI to production.
Our flexible manufacturing setup allows us to adapt to your project requirements, timeline, and production scale.
Whether you're validating a new design or preparing for mass production, we can support you at every stage.
