回答（1）：

SMT就是表面组装技术（Surface Mounted Technology的缩写），是目前电子组装行业里最流行的一种技术和工艺。
SMT有何特点：
1、组装密度高、电子产品体积小、重量轻，贴片元件的体积和重量只有传统插装元件的1/10左右，一般采用SMT之后，电子产品体积缩小40%~60%，重量
减轻60%~80%。
2、可靠性高、抗振能力强。焊点缺陷率低。
3、高频特性好。减少了电磁和射频干扰。
4、易于实现自动化，提高生产效率。降低成本达30%~50%。节省材料、能源、设备、人力、时间等。
为什么要用SMT：
1、电子产品追求小型化，以前使用的穿孔插件元件已无法缩小
2、电子产品功能更完整，所采用的集成电路(IC)已无穿孔元件，特别是大规模、高集成IC，不得不采用表面贴片元件。
3、产品批量化，生产自动化，厂方要以低成本高产量，出产优质产品以迎合顾客需求及加强市场竞争力
4、电子元件的发展，集成电路(IC)的开发，半导体材料的多元应用
5、电子科技革命势在必行，追逐国际潮流

通常包含下面这些设备：

Screen Printer
Pick and Place Machine
Convection Reflow Oven

There are three main pieces of equipment in our SMT line, fully computerized, each characterized by extreme accuracy, high throughput and maximum control.

The first unit in our SMT line is the SL-20 precision printer. This unit, built by deHaart Technologies, Inc., is a production line workhorse. It's engineered for continuous high volume printing of a flawless product. Tracking the details of each board is a vision system with pneumatic controls. A precision cam follower registration point ensures the accuracy of the print head and shuttle assembly. Truly unparalleled in its consistency, this marvel of production experience is just the beginning of our assembly process.

Next in our line is the ultimate pick and place machine from MYDATA automation. The MY12 HYDRA Speedmount® with DVS incorporates the most sophisticatedsoftware available for such a system. With TPSys® any combination of board types can be mounted in a single pass. This software even optimizes the assembly sequence. But that's not all. With this unit you get electrical verification of component placement "on the fly," vision alignment, and an advanced servo system for handling the most delicate and minute components. And with electronically encoded "smart" magazines, the system never needs to shut down. When one magazine runs out of components, the machine automatically picks from another.

At the end of our SMT line is Heller Industries' newest generation of reflow oven, the 1500W. This unit provides flexible and precise temperature control in a multizone-heating tunnel. Total forced convection is used to provide sharp and controllable temperature zones, thereby minimizing liquidous time. What's more, it even accommodates the largest of boards in its width-adjustable conveyor. The 1500W supports computer controlled line speeds up to 28 inches per minute. Rapid response times and precise temperature controls assure our process uniformity regardless of component density or board loading. From this unit surface mount boards emerge at exactly the right temperature at exactly the right time.
