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
♦ 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 |
