SMT PCB Assembly Manufacturer
SMT is surface mount technology, which is a new generation of electronic assembly technology developed from hybrid integrated circuit technology. SMT PCB assembly refers to a circuit assembly technology that installs SMC/SMD (Chip Components) on the surface of a printed circuit board or other substrate, and sells and assembles it by reflow soldering or dip soldering.
SMT PCB Assembly Development
With the development of science and technology, electronic products are becoming more and more miniaturized and precise, making the size of many SMD components smaller and smaller, not only the requirements for the processing environment are getting higher and higher, but also the SMT patch There are more and more production process requirements for processing, and the production requirements are also getting higher and higher; in the primary development stage of electronic products, via assembly is completely done manually. When the first automated machines came out, they could place some simple leaded components, but complex components still required manual placement for reflow soldering. With the development of science and technology today, PCBA production is completed through SMT+DIP.

SMT PCB Assembly Characterictics
1. High assembly density
Electronics are small in size and light in weight. Usually, after using SMT, the volume of electronic products is reduced by 40% to 60%, and the weight is reduced by 60% to 80%.
2. High reliability and strong anti-vibration ability
Since SMC and SMD have no leads or short leads, and are firmly attached to the surface of the PCB, they have high reliability and strong vibration resistance. Good high frequency characteristics.
3. It is easy to realize automation and improve production efficiency.
Compared with THT, SMT is more suitable for automatic production. For example, THT needs different plug-in machines (automatic plug-in machines, horizontal plug-in machines, vertical plug-in machines, taping machines, etc.) according to different components.
4. Can reduce costs.
Reduce the cost of manufacturing PCB; no-lead or short-lead SMC, SMD saves lead materials; omission of wire trimming and bending processes reduces equipment and labor costs; improvement of frequency characteristics reduces RF debugging costs; good reliability Reduce repair costs. Generally, the use of SMT in electronic equipment can reduce the total cost of the product by 30% to 50%.
