SMT is the full name of Surface mount(or Mounting) Technology. In Chinese, it means the Surface is stuck (or SMT refers to a series of process processes based on PCB. Printed Circuit Board (PCB) is a Printed Circuit Board.

Surface Mounted Technology (SMT) is the most popular Technology and process in electronic assembly industry. Electronic circuit Surface Mount Technology (SMT) is called Surface Mount or Surface Mount Technology. SMC/SMD is a Circuit assembly technology in which a pin or short lead surface assembly component (SMC/SMD in Chinese) is installed on the Printed Circuit Board (PCB) surface or other substrate surface and is welded and assembled by reflow welding or immersion welding.

Under normal circumstances, the electronic products we use are made of PCB plus a variety of capacitors, resistors and other electronic components designed according to the circuit diagram, so all kinds of electrical appliances need a variety of different SMT SMT processing technology to process.

Solder paste printing --> parts mounting --> reflow welding -->AOI optical inspection --> Maintenance --> plate.

Electronic products pursue miniaturization, the previously used perforated plug-in components can not be reduced. Electronic products function more complete, the use of integrated circuit (IC) has no perforated components, especially large-scale, highly integrated IC, have to use surface chip components. Product mass, production automation, the factory to low cost and high output, produce high-quality products to meet customer demand and strengthen the market competitiveness of electronic components, integrated circuit (IC) development, semiconductor materials of multiple applications. The revolution of electronic science and technology is imperative, chasing the international trend. It can be imagined that in the case of Intel, AMD and other international MANUFACTURERS of CPU and image processing devices, the production process has advanced to more than 20 nanometers, the development of SMT surface assembly technology and process is also unavoidable.

Advantages of SMT processing: high assembly density, small size and light weight of electronic products. The volume and weight of electronic products are only about 1/10 of that of traditional plug-in components. Generally, after adopting SMT, the volume and weight of electronic products can be reduced by 40%~60% and 60%~80%. High reliability and vibration resistance. Solder joint defect rate is low. Good high frequency characteristics. Reduced electromagnetic and radio frequency interference. Easy to achieve automation, improve production efficiency. Reduce cost by 30%~50%. Save materials, energy, equipment, manpower, time, etc.

It is because of the complexity of SMT processing process, so there are a lot of SMT processing factories, specializing in SMT processing, in Shenzhen, thanks to the booming development of the electronics industry, SMT processing achievements of an industry prosperity.
