Pintaliitoskomponenteilla, often abbreviated as SMT (Surface Mount Technology) components in English, are electronic components designed to be mounted directly onto the surface of a printed circuit board (PCB). Unlike older through-hole components, which have leads that pass through holes in the board, SMT components have small pads or terminations that are soldered to the surface of the PCB. This manufacturing method allows for smaller, lighter, and more densely populated electronic devices.

The development of SMT components revolutionized electronics manufacturing. It enabled the miniaturization of devices like mobile phones, laptops, and other portable electronics. The automation of SMT assembly lines is also highly efficient, using pick-and-place machines that can place thousands of components per hour with high precision. This leads to lower manufacturing costs and higher production yields.

Common types of SMT components include resistors, capacitors, transistors, integrated circuits (ICs), and diodes. They come in a wide variety of packages, such as SOICs, QFPs, BGAs, and 0402 or 0201 sizes for resistors and capacitors, indicating their physical dimensions. The soldering process for SMT components typically involves reflow soldering, where solder paste is applied to the PCB pads, the components are placed, and the entire assembly is passed through a reflow oven to melt the solder and create the electrical connections.
