With the rapid development of electronic technology and information industry, the technical equipment of electronic assembly has changed from labor-intensive manual mechanical operation to technology-intensive automated electronic assembly system in the production process of electronic products.
The appearance of Electronic PCB Assembly SMT technology fundamentally changed the traditional electronic assembly production form and became a new milestone of modern electronic assembly technology.
In addition to the size, Electronic PCB Assembly SMT technology allows automated production and soldering to be used, and this brings significant improvements in reliability.
-High assembly density, small size and light weight of electronic products, the volume and weight of SMT components only about 1/10 of the traditional cartridge components, generally used after SMT, electronic products volume reduced by 40%~60%, weight reduced by 60%~80%.
-High reliability and anti - vibration ability: Solder joint defect rate is low.
-High frequency characteristic is good: it can reduce electromagnetic and rf interference.
-Easy to realize automation and improve production efficiency: Cost of Electronic PCB Assembly SMT reduction up to 30%~50%. It save material, energy, equipment, manpower, time and so on.
SMT packages must withstand high temperature-resistant components and substrates that must have a matching coefficient of thermal expansion during soldering. These factors must be considered in the product design.
