12 Layer Industrial Control SMT PCB Assembly

 

 

♦ What Is SMT Assembly Service?

 

SMT Assembly (Surface Mount Technology Assembly)​​ is a modern method of mounting electronic components directly onto the surface of a printed circuit board (PCB). It is the most widely used PCB assembly technique today, replacing traditional through-hole technology (THT) in most applications due to its efficiency, precision, and ability to support miniaturized and high-density designs.

 

 

 

 Key Features of SMT Assembly Services:​

​​

1. Automated & High-Speed Process​​

    • Uses ​​pick-and-place machines​​ to accurately position tiny SMD (Surface Mount Device) components.
    • ​​Reflow soldering​​ melts solder paste to create strong electrical connections.
    • Ideal for ​​high-volume production​​ with consistent quality.

​​2. Supports Miniaturized & Complex Designs​​

    • Enables smaller, lighter, and more compact PCBs (e.g., smartphones, wearables, IoT devices).
    • Allows ​​high component density​​ (fine-pitch ICs, BGAs, QFNs, 01005 resistors, etc.).

​​3. Cost-Effective for Mass Production​​

    • Faster assembly than through-hole (THT), reducing labor costs.
    • Fewer drilling requirements (no holes needed for leads).

​​4. Common SMT Components​​

    • ​​Passive components​​ (resistors, capacitors, inductors)
    • ​​Integrated Circuits (ICs)​​ (QFP, BGA, SOIC, etc.)
    • ​​Connectors & LEDs​​ (small-footprint versions)

 

 

SMT vs. Through-Hole(THT) Assembly:​

Feature SMT Assembly Through-Hole Assembly (THT)
​Component Size​ Small (SMD) Larger (leads inserted into holes)
​PCB Space Used​ Less (higher density) More (requires drilled holes)
​Speed​ Faster (automated) Slower (manual or semi-auto)
​Cost​ Lower for mass production Higher (labor-intensive)
​Strength​ Less mechanical strength Stronger (better for high-stress parts)
​Applications​ Consumer electronics, IoT, medical devices Industrial, automotive, high-power circuits
