1. 国内规模最大的生产线用英文表示是：aproductionlineofthelargestscaleathome2.这句话翻译的核心词是生产线，首先翻译出productionline。国内规模最大是修饰生产线的修饰语，可以放在生产线的后面，用of来衔接。最大规模用最高级，thelargestscale.最后，国内可以翻译成athome。3.当然这句话也可以翻译成thelargestproductionlineathome.只要意思不错，一个句子可以有多重翻译方法。

SMT生产线：表面贴装生产线通常包含下面这些设备： ++++++Screen Printer Pick and Place MachineConvection 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.++++++你还可以了解以下公司和具体相关的产品，增加感性认识：DEK - Screen PrintingVitronics Soltec - Wave, Reflow and Selective SolderingUniversal Instruments - Surface MountHover Davis - Feederetc.
