SMD-- Surface Mount Device

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 the automated machines, which can put a few simple components pin, but the complexity of the components still need to be placed by hand for wave soldering. Surface mount components in about 20 years ago, and to open up a new era. From passive to active components and integrated circuit components, and eventually turned into a surface mount device (SMD) and through the pick-and-place equipment Assembly. In a long time people think that all the components of the final pin SMD package can be used.
