In today's fast-paced electronics industry, product complexity and performance requirements continue to rise. As devices become smaller yet more powerful, manufacturers seek efficient and cost-effective ways to integrate multiple technologies into one board. This is where Mixed PCB Assembly comes in — a hybrid process that combines both Through-Hole Technology (THT) and Surface Mount Technology (SMT) on a single printed circuit board. At Shenzhen Fanway Technology Co., Ltd, we specialize in delivering high-precision mixed PCB assembly solutions designed to meet the evolving needs of industries such as telecommunications, automotive, medical, and industrial automation.
Mixed PCB Assembly refers to a manufacturing process that integrates both SMT and THT components on the same PCB. SMT components are mounted directly onto the board's surface, ideal for compact and lightweight designs, while THT components are inserted into pre-drilled holes, providing strong mechanical stability for high-power or large components. By combining these two methods, engineers can enjoy the best of both worlds — flexibility, performance, and cost-efficiency.
| Feature | SMT (Surface Mount Technology) | THT (Through-Hole Technology) |
|---|---|---|
| Mounting Method | Components soldered on surface | Components inserted through holes |
| Strength | Suitable for lightweight parts | Excellent for heavy-duty parts |
| Automation | Fully automated | Semi-automated or manual |
| Applications | Smartphones, laptops, IoT devices | Power supplies, connectors, relays |
| Cost | Lower assembly cost | Slightly higher due to manual steps |
By combining the advantages of both assembly techniques, Mixed PCB Assembly provides unmatched versatility. It allows complex products to function seamlessly while maintaining cost efficiency and production flexibility.
Enhanced Design Flexibility – Ideal for boards requiring both high-density and high-durability components.
Improved Reliability – THT ensures mechanical stability, while SMT provides compactness.
Cost Optimization – Reduces the need for multiple boards, simplifying the design and manufacturing process.
Better Performance – Enables integration of analog, digital, and power circuits on one board.
Wide Industry Applications – From medical devices to consumer electronics, mixed assembly is used everywhere.
At Shenzhen Fanway Technology Co., Ltd, our process follows strict quality protocols to ensure each product meets global manufacturing standards.
PCB Preparation – Clean and inspect the bare board.
SMT Assembly – Apply solder paste, place SMT components, and perform reflow soldering.
THT Assembly – Insert larger components and solder manually or via wave soldering.
Inspection & Testing – Conduct AOI, X-ray, and functional testing.
Final Assembly – Integrate modules, finalize connections, and perform a final inspection.
The performance improvements brought by Mixed PCB Assembly are substantial. Combining SMT and THT enhances signal integrity, heat dissipation, and mechanical strength. Products manufactured with this method are known for their superior performance and reliability, especially in demanding environments such as automotive control systems or aerospace equipment.
Our clients report improved production yields, reduced repair rates, and shorter time-to-market cycles — making Mixed PCB Assembly a strategic choice for any competitive electronics business.
As technology continues to evolve, mixed assembly has become more than just an option — it's a necessity. By adopting this method, manufacturers can design multifunctional products without compromising size or performance. At Shenzhen Fanway Technology Co., Ltd, we understand that reliability and precision are critical in every step of PCB production, and that's why our engineers use advanced equipment and strict process control to ensure consistent results.
