SMT, also known as surface mount technology or SMT, is currently the most popular technology and process in the electronic assembly industry. In television shows, it is basically synonymous with high-tech. SMT is the process of accurately brushing tin onto the solder pads of a circuit board, then using a SMT machine to pick up the SMT components and place them on the predetermined solder pads of the circuit board, and then placing them in a furnace for high-temperature melting of tin to complete the welding process. Prior to this, electronic products used plug-in welding technology, and the advantages of SMT were high density, high precision, low component prices, and high production efficiency.
Density: Modern products strive for both powerful functionality and exquisite size. For example, in a mobile phone, more and more functions are integrated: previously, GPS navigation, radio, dictionary, camera, Bluetooth, scanner, etc. were all separate devices, but now they can all be integrated into the phone. This requires components to be as small as possible, and as many components and circuits as possible can be placed in a limited area, which can only be achieved by SMT technology. The area of a fingernail can only accommodate about 5 components using plug-in welding technology, while several hundred components can be accommodated using SMT technology.
Precision: High density requires high precision. High accuracy is the characteristic of SMT.
Price of SMT components: Due to the suitability for large-scale production, small size, and low consumption of raw materials, SMT components have a lower cost than plug-in components.
Production efficiency: Due to the fact that SMT components can be automatically produced using a mounting machine, while plugins are generally manually operated, the production efficiency of SMT is several times ten times that of plugins. In today's increasingly artificial world, plugins can only be gradually phased out.

SMT is a high-tech foundational industry, and it can be said that 95% of electronic products now require SMT for processing. The more precise and high-end products are, the more SMT is needed. The technological content of SMT is also very high. Currently, the main equipment of SMT - SMT mounting machines - sells 20000 units worldwide each year, with a market of one million to several million RMB. However, there is no company in China that can produce practical mounting machines, all of which are imported from Japan, Germany, the Netherlands, and South Korea. High end SMT technology, such as processing BGA, QFN, POP, and many factories do not have relevant equipment and technical capabilities.

At present, China's SMT industry accounts for two-thirds of the weak in the Pearl River Delta, one-third in the Yangtze River Delta, and the remaining in the Bohai Rim and other regions. SMT factories with more than ten production lines can be referred to as large factories. They belong to large companies or rely on large consortia, with investments ranging from tens of millions to hundreds of millions. They have strong technical capabilities and good production quality, but basically only target and rely on a few top 500 customers for processing. A large number of small factories have one to five production lines, with 99% of them purchasing second-hand SMT machines that have been phased out by large or overseas factories, with a usage age of about ten years and an investment of tens to millions. They specialize in processing for small and medium-sized customers.
