The full name of SMT is surface mount technology, a new method of arranging components on PCB. This technology is widely used in the PCBA industry, and almost all companies that provide PCB assembly services can provide SMT assembly services. In the early 1970s, electronic manufacturers used through-hole assembly to realize component mounting and soldering work, that is, the leads of components were placed in drilled holes on bare PCBs, and permanent component through-hole arrangements were achieved through soldering guns. However, with the development of technology, people gradually found that through-hole PCB assembly is not the best solution, and SMT assembly may serve as a replacement.
Unlike plug-ins, SMT technology uses leadless assembly to solder components directly to the bare PCB, which is a faster and more cost-effective assembly method. For some consumer electronic devices (mobile phones, computers, etc.), their update frequency is less than a year, which means that electronics manufacturers urgently need automated PCB assembly to achieve large-scale production, and SMT technology simply meets this requirement.
