SMD LED

 is an acronym for Surface Mounted Devices, which means: surface mount devices, it is a SMT (Surface Mount Technology Chinese: Surface Mount Technology) components in a.
"In the electronic circuit board production in the initial stage, through-hole assembly to be completed entirely artificial. The first batch of the introduction of automatedmachinery, they can put some simple pin device, but the complexity of the components still need to be manually placed to wave soldering. surface mount components to launch inabout two decades ago, and this ushered in a new era. from passive components to active components and integrated circuits, eventually turned into a surface mount device (SMD)and through the pick-and-place equipment assembly. in a very long time that all people are the final components of the pin SMD package can be used. In addition to SMD but alsohave:
SMC: Surface Mount Components (Surface Mounted commponents)
There are rectangular chip components, cylindrical chip components, composite components, shaped chip components.
