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. One of the key advantages of surface-mount technology is its compatibility with automated assembly processes. Machines can quickly and accurately place components on the PCB, leading to faster production times and reduced labor costs. This technology is widely used in various electronic devices, including smartphones, computers, and other consumer electronics.
