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 and efficiency. SMT components are typically smaller than traditional through-hole components, which helps in creating compact electronic designs. 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 home appliances.
