SMD: it is the abbreviation of surface mounted devices, which means surface mount devices. It is a kind of SMT (surface mount technology) components. In the primary stage of electronic circuit board production, through hole assembly is completely completed by hand. After the introduction of the first batch of automatic machines, they can place some simple pin components, but complex components still need to be manually placed before reflow soldering. Surface mounted components mainly include rectangular chip components, cylindrical chip components, composite chip components and special-shaped chip components.
