What is SMT?

Technology, which means surface mounting technology in Chinese, is a technology applied to the electronic assembly industry, mainly involving the process of fixing electronic parts to the surface of printed circuit board (PCB) by welding or bonding. The specific content of SMT will be introduced in detail below.

First, the basic concept of SMT

SMT is an assembly technology to fix electronic parts to the surface of printed circuit board (PCB) by welding or bonding. It mainly consists of the following steps: parts placement, fixing, welding or bonding, inspection and repair. SMT has a wide range of applications, including consumer electronics, communication equipment, automotive electronics, industrial control and other fields.

Second, the history and development of surface mount technology

SMT originated in 1960s. At that time, due to the appearance of some miniaturized electronic devices, the traditional large-scale integrated circuit (ic) packaging method could not meet the needs of these devices, so SMT began to be used in the field of electronic assembly. With the continuous development of science and technology, SMT technology is constantly improving and perfecting, and now it has become an important technology in the electronic assembly industry.

Third, the advantages of surface mount.

Compared with the traditional manual assembly method, SMT has the following advantages:

1. The assembly density is higher, and the miniaturization and miniaturization of parts can be realized;

2. The production efficiency is higher, which can greatly shorten the production cycle;

3. The reliability is higher, because the parts are firmly connected with the circuit board, the faults caused by poor contact or looseness are reduced;

4, the manufacturing cost is lower, automatic production can be realized, and the labor cost is reduced.

Fourthly, the future development of surface mount technology.

With the continuous development of science and technology, SMT technology is also constantly improving and perfecting, and the future development of SMT will develop in the following directions:

1. high precision: with the continuous reduction of parts size, the precision requirements for SMT are getting higher and higher;

2. Intelligent manufacturing: by introducing artificial intelligence, machine learning and other technologies, the automation and intelligence of SMT production process are realized;

3. Environmental sustainability: With the improvement of environmental awareness, environmental protection and sustainability in SMT production will also receive more attention.
