Automatic 10 zones lead free Nitrogen reflow oven LEAD SMT patent heating technology
1. Lenovo PC , windows 7 operation system, Chinese-English interface screen.
2.All production data will be backup automatically,which is suitable for the ISO9000 management.
3.Fault Intelligent Diagnosis,display alarm and list out.
4.15% heat transferring efficiency was improved ,which is more suitable for the LEAD-FREE welding process.
5.Guide rail is through the special heat treatment, it's hard to out of shape.
6.The main hanging is reinforced, which can avoid the deforming and PCB jamming.
7. Siemens PLC control, more durable and stable.
8.The most energy saving reflow oven
The machine adopts heating method of imported heating board with even temperature and high heat compensation efficency,is especially suitable for sold of BGA CSP components.
The patent wind wheel design can ensure wind speed wind speed can be adjusted by frequency conversion.
All temperature zone apply coercive didependent cycles PID controls and up and down heating style,which make the temperature of the oven accurate with large heat capacity.
The heating is quick,it takes less than 30 minutes ti heat from the normal temperature to the working temperature.
Power by the imported high temperature high speed motor with high quality,hot wind created is stable with no vibration and noise.
The upper cover of the oven is raised by electric handspike,safe and credibie.
The inphase parallel conveyor of chains and mesh which adopts step less speed regulating.
The track are made of special aluminum alloy with high rigidity accuracy and intensitymauto chain lubrican filling system.
UPS power off protection function which ensures the normal output of PCB board without damage after the power is off.
Powerful programming software’s controlling system, It can detect the online temperature of PCB and can analysis,save and type the
MODBUS protocol is adopted in PC and PLC communication works stably without system halting.
Automatically monitoring and displaying the working condition of the oven the parameter of the oven can be modified at any moment.
Special solder design, best temperature saving, lowest power consumption in the same field.
Compel water cooling quick and even, the speed can be controled by frequency conversion, no temperature rebound which makes
soldered point smooth and shining.
The nitrogen flowmeter enable you to know the nitrogen flux anytime.
Quickly extracting oxygen and charging with nitrogen which can provide high purity nitrogen easily.
Vertical nitrogen anti leak technology to prevent the leaking of nitrogen.
