What Is Surface Mount Technology (SMT)?

Surface mount technology (SMT) is a method of assembling printed circuit boards where components are mounted directly onto the surface of the board, rather than through holes. SMTFullLine manufactures and supplies SMT equipment for all production scales, from prototyping to high volume.

How SMT Works

1. Solder paste printing – Paste is deposited on PCB pads.

2. Component placement – Pick‑and‑place machines position components on the paste.

3. Reflow soldering – The board is heated to melt solder and form permanent connections.

4. Inspection – AOI/SPI verify quality.

Why SMT Dominates Modern Electronics

• Smaller components – Enables compact, lightweight products.

• Higher density – Components on both sides.

• Faster assembly – Automated placement thousands of parts per hour.

• Lower cost – Less material and drilling.
