Definition of SMT: Surface mount technology refers to the surface mount device mounted on the printed circuit board surface of a technology, the technology makes electronic products more light, thin, short, small, multifunctional, high reliability, low cost and a series of advantages. After years of development, SMT technology has been quite mature, has been widely used in computer, communication, consumer electronics, industrial automation and other electronic manufacturing industry. In the supply chain of electronic manufacturing industry, manufacturing has become a more important link.

Current situation of SMT:

Phase I (1960-1975) : Miniaturization, hybrid integrated circuit (calculator, quartz watch)
Phase II (1976-1980) : Reduced size, enhanced circuit functionality (Camcorder, video recorder, digital camera)
The third stage (1980-1995) : reduce the cost, vigorously develop the production equipment, and improve the cost performance of products (ultra-large scale integrated circuit)
Current stage (1995-present) : micro-assembly, high-density assembly, three-dimensional assembly

On the future of SMT:

New technology revolution and cost pressure give birth to automated, intelligent and flexible manufacturing, assembly, logistics assembly, packaging, testing integrated system MES. SMT equipment through technological progress to improve the automation level of the electronics industry to achieve less work, reduce labor costs to increase individual output, maintain competitiveness, is the main melody of SMT manufacturing industry. High performance, ease of use, flexibility and environmental protection are the inevitable trends of SMT equipment development.
