Product Description

One-Stop SMT PCB Manufacturing for Consumer Electronics

 

♦ What is SMT PCB Manufacturing?

 

​​SMT (Surface Mount Technology) PCB Manufacturing​​ is the process of assembling printed circuit boards by mounting electronic components directly onto the surface of the PCB using automated machines, as opposed to through-hole technology (THT), where components are inserted into drilled holes.

♦​​ Key Steps in SMT PCB Manufacturing​​

1. PCB Fabrication (Before SMT Assembly)​​

    • The bare PCB is manufactured with solder pads (no holes needed for SMT components).
    • Common materials: FR-4, aluminum, or flexible substrates.

​​2. Solder Paste Application​​

    • ​​Stencil Printing​​: A metal stencil aligns with the PCB, and solder paste (a mix of tiny metal balls and flux) is applied to the pads.

​​3. Component Placement​​

    • ​​Pick-and-Place Machines​​ automatically pick SMDs (Surface Mount Devices) from reels/trays and place them on the solder paste with high precision.
    • Components include resistors, capacitors, ICs (QFN, BGA), and more.

​​4. Reflow Soldering​​

    • The PCB passes through a ​​reflow oven​​, where controlled heating melts the solder paste, forming permanent electrical connections.
    • Temperature profile: Preheat → Soak → Reflow → Cooling.

​​5. Inspection & Testing​​

    • ​​AOI (Automated Optical Inspection)​​ – Checks for misalignment, solder defects.
    • ​​X-Ray Inspection​​ – For hidden joints (e.g., BGA components).
    • ​​Functional Testing​​ – Validates the assembled PCB’s performance.

 

♦ ​​​​​​SMT vs. Through-Hole (THT) PCB Assembly​​​​​​

 

Feature SMT PCB Assembly Through-Hole (THT) Assembly
​Component Size​ ✅ Tiny (0201, 0402) ❌ Larger (leaded parts)
​Speed​ ✅ Faster (automated) ❌ Slower (manual/semi-auto)
​Cost​ ✅ Lower (mass production) ❌ Higher (labor-intensive)
​PCB Space​ ✅ High-density ❌ Requires more space
​Strength​ ⚠️ Less mechanical strength ✅ Better for high-stress environments
