About SMT
Addtime:2011-11-13

SMT (Surface Mount Technology) is an emerging high-tech electronic processing technology, it wide range of applications, for example, communication systems, PC, consumer electronics, defense, automotive industry, are inextricably linked with the SMT, a cell phone, any computer, any manufacturer can not do without a car SMT. Thus, in the global electronics manufacturing, there has been a bright spot, as the main technique is to SMT processing and manufacturing (OEM) came into being.
SMT is the one involving mechanical, chemical, electronics, automation and many other areas of technology. Its entire process, including raw materials inspection, solder paste /glue printing, parts placement, reflow soldering, optical detection, electronic functional testing, and CONFORMING COATING and final packaging. Used throughout the process machines and testing equipment is very expensive, usually a total value of production of 100 million dollars or more, and are controlled by the microcomputer, so the programming for the machine, use, maintenance, and maintenance is very important. And because of the high integration of modern spare parts, the demand for miniaturization, from the ordinary IC (integrated circuit) development to the BGA, CSP, by the ordinary large-size resistors and capacitors, to the present 0201 resistors and capacitors, which virtually increase the SMT the difficulty of processing technology, thus engineering and technical personnel to a new subject, new challenges, because SMT-related materials, equipment, software development are constantly, also requires engineering and technical personnel to update their knowledge, rich experience, expand the scope of knowledge to accommodate this development.
SMT is currently very widely quoted in Canada, especially in the automotive electronics, communications and computer industry, there are a lot of SMT electronic processing factories, jobs work in this area Many, for electronic, mechanical, and automation in terms of background, friends, is a very good direction to find a job job. The main jobs are: process /manufacturing engineers, product engineers, maintenance technicians, programmers, machine operators, inspectors, members of manual welding and testing technician.

three surface mount basics
1 high-density assembly, electronics, small size, light weight, chip component size and weight of traditional plug-in components only about one-tenth of the general use of SMT, electronic products, reduce the volume of 40% -60%, 60% weight -80%
(2) high reliability, strong anti-vibration, solder joint defect rate.
3 High-frequency characteristics, and reduce electromagnetic and radio frequency interference.
4 easy to automate, improve productivity and reduce costs by up to 30% -50%
5 to save materials, energy, equipment, manpower and time.
Four, SMT features
Why use surface mount technology SMT
1 electronic pursuit of miniaturization. Perforation has been previously used plug-ins can not be reduced.
(2) a more complete electronic product features, using the integrated circuit (IC) has not perforated components.
Especially large-scale highly integrated IC, had to use surface mount components.
3-volume products, production automation, factory production to low cost high quality products to meet customer needs, enhance market competitiveness.
