Something you must know about smt machine

The meaning of SMT：

Surface mounted technology stands for surface-mount technology. Is the most popular electronic assembly industry in a technology and process. It is an unleaded or short-lead surface mount component (SMC/SMD) mounted on the surface of a Printed Circuit Board (PCB) or other substrate Printed Circuit Board, a technique of assembling a circuit by means of reflow or immersion welding.

Advantages of SMT:

1 High Assembly density, small volume and light weight of electronic products, the volume and weight of SMT components is only about 1/10 of that of traditional cartridge components, electronics shrink by 40% “60% , weight by 60% 80% .

2 High reliability, Strong anti-vibration ability. Low defect rate of solder joint.

3 good high frequency characteristics. Reduced electromagnetic and radio frequency interference.

4 It is easy to realize automation and improve production efficiency. REDUCE COSTS BY 30% ~ 50% . Save material, energy, equipment, manpower, time, etc.

Problem：

Of course, there are some problems in SMT production, such as: The nominal value on the components is not clear, the maintenance work is difficult; the maintenance and replacement of the components is difficult, and tools are needed; the consistency between the components and the Printed Circuit Board Coefficient of thermal expansion is poor, and the power is small, it is small in size. Easy to be damaged, not easy to use visual inspection, testing and inspection of high difficulty, technical complexity, the need for higher training and learning costs. But these problems are in the development of the problem, with the emergence of disassembly equipment, as well as the emergence of a new low expansion coefficient printed circuit board, are no longer an obstacle to the development of SMT in-depth.

Development Trend:

As a new generation of electronic assembly technology, SMT has developed rapidly in the past 20 years and has been widely used, and in many fields, it has partially or completely replaced the traditional through-hole insertion technology of circuit boards, especially since 2017, China’s key breakthroughs in chip technology, the localization of CPU processors, etc. , china’s electronics and information products manufacturing industry grows at a high speed every year. The scale of the electronics industry has been the world’s largest for three consecutive years since 2010. With the rapid development of China’s electronic and information industry, China’s surface-mount technology and production lines are also getting bigger, the number of automatic SMT machines, the key equipment of SMT production line, is among the largest in the world.

Three Basics

1, cost base: reduce costs, now whether SMT chip processing or other industries, the lower the cost will mean higher profits, the more competitive advantage in the market, it will have a positive impact on resource aggregation, configuration, supply and demand connection, customer experience, and subject coordination.

2. High efficiency: The design and dynamic adjustment of the process is very important to the management mode of the factory production. The rationalization of the equipment automation and management and the humanization of the software are the important factors of high efficiency.

​3, good quality: reasonable process, complete system, mature technology, advanced equipment, management innovation is the basis of quality assurance.
