question: what is SMT? What does SMT mean?
SMT is the surface mount technology (Surface Mounted Technology abbreviation), is a kind of technique and technology of the electronic assembly industry's most popular. It will become the electronic components traditional compression device volume is only one of dozens, so as to realize the assembly of electronic products of high density, high reliability, miniaturization, low cost, and the automation of production. The miniaturization of components is called: SMY devices (or SMC, chip device). The element is mounted to the printed (or other substrate) process called the SMT chip processing technology. Assembly equipment related to it is called a SMT device. At present, advanced electronic products, especially in the computer and communication electronics products, has been widely used for SMT technology. International SMD device production increased year by year, but the traditional device yield decreased year by year, so as time goes on, the SMT technology will become more and more popular. What are the characteristics of SMT:
1, the assembly of electronic products of high density, small volume and light weight, the volume and weight of the traditional patch element only inserted element around 1/10, after the general use of SMT, reducing the volume of electronic products 40%~60%, weight 60%~80%. 2, high reliability, strong anti vibration ability. Solder joint defect rate is low. 3, good performance of high frequency. Reduce the electromagnetic and radio frequency interference. 4, easy to realize automation, improve production efficiency. To reduce the cost of up to 30%~50%. Save material, energy, equipment, manpower, time, etc.. Why use surface mount technology (SMT)?
1, the pursuit of the miniaturization of electronic products, previously used to insert elements have been unable to reduce
2, electronic products, function more complete, integrated circuit (IC) has been adopted by the non perforated element, especially large scale, Gao Jicheng IC, had to use surface mount components.
3, product batch, production automation, management must take the low cost and high yield, produce quality products to meet the customer needs and strengthen the market competitiveness of
4, the development of electronic components, integrated circuit (IC) development, multiple applications of semiconductor materials 5, electronic technology revolution is imperative, chasing the international trend of
