Surface-mounted device (SMD)

A surface-mounted device or SMD is an electronic device for which the components are mounted or placed directly onto the surface of the PCB. Surface-mount technology, or SMT, is the name of the method used for producing an SMD. Surface Mounted Devices (SMD) and Surface Mount Technology (SMT) are two types of technologies used in the electronics industry. SMD is a type of device that is soldered directly onto a printed circuit board (PCB). SMT is a type of technology used for mounting of SMDs onto PCBs.
