Surface-Mount Technology (SMT) is a method used to mount electronic components directly onto the surface of printed circuit boards (PCBs). This technique allows for smaller and lighter devices, as components can be placed on both sides of the board, maximizing space efficiency. SMT components are typically smaller than traditional through-hole components, which require holes to be drilled into the PCB. SMT has become the standard in modern electronics manufacturing due to its speed and cost-effectiveness. Automated machines can quickly place thousands of components per hour, significantly reducing production time. This technology is widely used in various devices, from smartphones to computers and household appliances.
