OUR PROCESS
Your Dedicated Printed Circuit Board Assembly Partner
Define Your Vision. Send Us Your Project Specifications
Clear, detailed specifications are the foundation of a successful project.We’ll start with a complete Bill of Materials (BOM), environmental and performance requirements, and ensure your product is built exactly as needed
Optimize Design and Identify Challenges Early
We don’t just assemble; we optimize. By incorporating Design for Manufacturability (DFM), we prevent costly mistakes early and suggest alternatives to ensure your design is production-ready and reliable.
Build a Robust and Reliable Supply Chain
Our trusted supplier network and proactive stock management minimize risks and keep your project on track. We anticipate component shortages and provide alternatives to avoid delays.
Precision PCB Assembly with Cutting-Edge Technology
Using the latest technology, we deliver precise surface mount and through-hole assemblies. Our automated equipment and expert team ensure every PCB meets the highest quality standards
Rigorous Testing to Ensure Peak Performance
Our comprehensive testing includes 3D AOI, in-house X-ray, and functional testing to ensure every board meets IPC-A-610 Class II and III standards for reliability and performance.
Ongoing Quality Control and Continuous Improvement
We maintain rigorous quality control throughout the process, with continuous improvement to ensure your PCB meets the highest standards for reliability, durability, and consistency.
Getting Your Products to Market Faster
With our Production Introduction (NPI) process we can commit to purchasing components for the full production order, but provide you with a small batch of assemblies to validate your design and test the first units. This approach reduces the time between design approval and full production, and makes it easier and more affordable to make adjustments. Any changes to the design or process can be quickly accommodated.

CHOOSING THE RIGHT APPROACH
Surface Mount and Through-Hole Technology
What is the difference between surface mount (SMT) and through-hole technology (THT) in the printed circuit board assembly process?
Every board begins with a substrate that can consist of multiple layers of copper foil routing. Many PCB assemblies are of a hybrid nature, blending through-hole and surface mount technology (SMT), with the majority of the components surface mount and a few larger or heavier components through-hole mounted.
Surface Mount Technology (SMT)
- Most Common and Cost-Effective
- High-Density Component Placement
- Automated Process
- Ideal for Small, Lightweight Components
- Faster assembly process
- Reduced size and weight of finished products
Through-Hole Technology (THT)
- Stronger, More Durable Bonds
- Component Leads Inserted into the Board
- Used for Larger, Heavier Components
- Suitable for high-stress applications
- Better for heavy components or components with leads
Hybrid (Mixed Technology) Assemblies
- Blending Both Methods: Most of our PCBA projects are hybrid assemblies, combining the best of both SMT and THT.
- Flexibility in Design: This combination allows for both the high-density advantages of SMT and the durability of THT.
