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 require holes to be drilled into the PCB. SMT has become the standard in modern electronics manufacturing due to its advantages in automation and production speed. It enables the use of advanced machinery for soldering and placement, improving the overall quality and reliability of electronic devices. This technology is widely used in various applications, from consumer electronics to industrial equipment.
