SMT Definition
Surface-mount technology (SMT) is a method in which the components or ICs are mounted directly onto the surface of a printed circuit board (PCB). An electrical component mounted in this manner is referred to as a surface-mount device (SMD). In industry, this approach has largely replaced the through-hole technology construction method of fitting components, the main reason is that SMT allows for increased manufacturing automation. Both technologies can be used on the same board, with the through-hole technology often used for components not suitable for surface mounting such as large transformers and heat-sinked power semiconductors.
The Advantages of SMT Technology in PCB Designs.
The important advantage of SMT in manufacturing includes reduced board cost, reduced material handling costs, and a controlled manufacturing process. Routing of traces is reduced, the size of the board is reduced, and number of drilled holes are also reduced
