Study Notes
Surface Mount Technology
- An electrical component mounted directly onto the surface of a printed circuit board is referred to as a Surface Mount Device (SMD).
- The method in which electrical components are mounted directly onto the surface of a printed circuit board is known as Surface Mount Technology (SMT).
Advantages of SMT
- Surface-mount technology allows for more components to fit on a given area of substrate because SMT components are smaller and have a lower profile than through-hole components.
- SMT has largely replaced through-hole technology in industry due to its increased component density and reduced production costs.
Characteristics of SMT Components
- SMT components are usually smaller than their through-hole counterparts due to the absence of lead wires and the ability to mount them directly onto the surface of the board.
