the product name is PCB SMD Assembly

Normally PCB assembly procedure will use SMT. SMD is an acronym for Surface Mounted Devices, which means: Surface mount device, which is one of SMT (Surface Mount Technology) components. At the initial stage of electronic circuit board production, via assembly is completely done by hand. After the first automated machines were introduced, they could place some simple pin components, but complex components still needed manual placement for wave soldering. Surface Mounted components mainly include rectangular chip components, cylindrical chip components, composite chip components, and odd-shaped chip components. XD has more than ten years of PCB SMD Assembly experiences. url:http://www.xdxpcb.com
