Adopt new efficient DEK Cyclone at the bottom of the Duo stencil cleaning system, can maximum limit reduce cleaning time and material used. 
 
Focus on SMT full production, SMT placement machine high performance efficiency high integration 
 
Placement machine is used to realize high-speed, high-precision, fully automatic stick put equipment, related to the efficiency and precision of SMT production line, SMT production line is the most critical, the highest technical and stability requirements equipment, often accounts for the whole production line more than half of the amount invested, the development trend of the "four modernizations" three highs available to generalize, namely, high performance, high efficiency, high integration, flexible and intelligent, greening, diversification. 
 
Specifically, SMT placement machine after three generations of development, has been from the early low speed (1-1.5 seconds/plate) and (mechanical) in the development of low precision to 0.08 seconds (/) with high speed and high precision (precision optical on, patch + 60 um / 4 q) automatic placement machine. The first generation of placement machine does not have visual identification device, the precision of servo system, automatically send plate and automatic in mouth function, only the high accuracy stepper multi-axis system; Has visual identification function the second generation of SMT machine, SMT also by two extended to more quantity, automatic transmission and imported servo technology XY system can also import; The third generation of placement machine has a higher level of ascension, such as device identification and placement optimization function, Z axis high precision servo technology USES, for different devices and the thickness of the IC test and supply, high precision of SMT, the third generation of SMT machine, in fact, a kind of precision industrial robots, by computer, optics, precision machinery, ball screw, linear guide, linear motor, harmonic drive and vacuum system and various sensors composed of mechanical and electrical integration of high-tech equipment. 
 
 
 
Accompanied by a variety of electronic equipment miniaturization, high functionality, in SMT form to the requirement of high density and the complication is higher than now, especially for SMD and semiconductor mixed load demand is increasing. In order to promote lower production cost and shorten the time of delivery, Fuji machinery manufacturing co., LTD (Shanghai electronic production equipment exhibition 2017 Munich, booth no. : E3 3106) developed the process after the combination of the semiconductor into the NXT -h SMT process. NXT - H in high precision with significantly more than the general placement machine at the same time, to achieve the high productivity, SMT precision maximum plus or minus 5 microns, production capacity of up to 24900 CPH. NXT -h inherited factory sets 53000 module NXT series concept, as is given priority to with SMT working head of the unit after the modularization, through wafer supply device MWU12i, widely corresponding 4, 6, 8, 12 inch wafer size, change module can use 1 machine mount up to 25 kinds of wafer. 
 
High quality with green, SMT reflow soldering pay more attention to energy conservation and environmental protection 
 
SMT reflow soldering is formed through to melt the solder side of pre-positioned solder joints, not add any additional solder in welding process of a kind of welding method, through the heating circuit inside the equipment, will air or nitrogen blow after heated to a high enough temperature to have good components of circuit boards, components on both sides of the solder melts and motherboard binding, has become the mainstream of the SMT process. Components are mostly through this process for the board on the welding on the PCB. 
 
However, air quality deteriorating, SMT welding equipment environmental protection sex also slowly by increasingly more people attention. "Thermal equipment (dongguan) co., LTD. (Shanghai 2017 Munich, electronic production equipment exhibition booth number: E3 3106) VisionXP + Vac welding system adopted in accordance with the present trend of energy conservation and environmental protection concept, and the high quality sustainable production combined with modern manufacturing requirements, especially pay attention to in the process of research and development factors, such as high efficiency, low emissions, and the lowest cost is efficient energy-saving assistant. The system is equipped with a new vacuum unit module, can implement vacuum reflow soldering step, directly and effectively solved after welding (when the solder is in a state of optimal fusion) porosity, empty and void problem: 2 mbar vacuum can be empty rate below 2%. VisionXP + Vac module vacuum unit adopts the design can be separated, therefore can be used for the vacuum reflow soldering process, flexible matching different production requirements.
