SMT is the electronic surface assembly technology (Surface Mounted Technology abbreviation), also known as surface mount or surface mount technology, mainly including printing, placement, welding three major process technology, is currently the most popular technology and process in the electronic assembly industry.
High assembly density, small size and light weight of electronic products, the volume and weight of SMD components is only about 1/10 of the traditional THT components, generally after the use of SMT, electronic products volume reduction of 40% to 60%, weight reduction of 60% to 80%. High reliability, high vibration resistance. Low defect rate of solder joints. Good high frequency characteristics. Reduced electromagnetic and RF interference. Easy to automate and improve production efficiency. Reduce cost up to 30%~50%. Save material, energy, equipment, manpower, time, etc.
3、Why use SMT
The pursuit of miniaturization of electronic products, the previous used though hole components volume have been unable to reduce; electronic products functions are more complete, the integrated circuit (IC) has been used without THT components, especially large-scale, highly integrated IC, had to use surface mount components; product batching, production automation, SMT chip processing plant to provide low cost and high yield, produce high-quality products to meet customer demand and strengthen market competitiveness; the development of electronic components, integrated circuits (IC) development, semiconductor materials for multiple applications; electronic technology revolution is imperative, chasing the international trend.
4、SMT technology advantages
High market demand: Since 2000, China's electronic products have been growing at a rate of 30% per year, and the annual shortage of skilled workers is as much as 300,000.
Beautiful working environment: the workshop is a clean workshop, central air conditioning control, temperature control at 25±3 degrees throughout the year.
High technical content: covers chemistry, materials, electronics, welding, precision machinery and mechanical automation and statistical related knowledge.
Broad career prospects: learning the technology well can be engaged in jobs of SMT equipment, industry, design, service, etc.
Great professional advantage: The profession is not offered in national middle and high schools, learn the technology well and improve the competitiveness of employment.
