Surface Mount Technology (Surfacd Mounting Technolegy referred to as SMT) is a new generation of electronic assembly technology, which will be the traditional electronic components
compressed into a volume of only a few tenths of the device, thus realizing the electronic product assembly of high-density, high-reliability, miniaturization, low-cost
and production automation. p>
And production automation. This miniaturized components called: SMY devices (or SMC, chip devices). The process of assembling components onto a printed
(or other substrate) is called the SMT process. The associated assembly equipment is called SMT equipment.
Currently, advanced electronic products, especially in the computer and communications electronics, has been widely used SMT technology. Internationally, the production of SMD devices
devices is increasing year by year, while the production of traditional devices is decreasing year by year, so with the passage of time, SMT technology will become more and more popular.
Or:
SMT is Surface Mounted Technology (Surface Mounted Technology acronym), is currently the most popular electronic assembly industry in a technology and process.
What are the characteristics of SMT:
High assembly density, small size and light weight of electronic products, the volume and weight of the SMD components is only about 1/10 of the traditional plug-in components, generally after the use of SMT, the size of the electronic products is reduced by 40% to 60%, the weight is reduced by 60% to 80%.
High reliability and vibration resistance. Low solder joint defect rate.
Good high frequency characteristics. Reduced electromagnetic and radio frequency interference.
Easy to automate and improve productivity. Reduce cost up to 30%~50%. Save material, energy, equipment, labor, time, etc.
Why SMT:
Electronic products in pursuit of miniaturization, the previous use of perforated plug-in components can not be shrunk
Electronic products are more complete functionality, the integrated circuits (ICs) used are no longer perforated components, especially large-scale, high-integration ICs, had to use the surface mount components
Products batch, production automation, the factory
The development of electronic components, the development of integrated circuits (ICs), semiconductor materials, multiple applications
The revolution in electronic technology is inevitable, chasing the international trend .
