What is SMT reflow oven?
In SMT reflow systems the heat tranfer takes place by full convection. Heated process gas (air, nitrogen) is guided on the products by nozzle plates. The resulting temperature profile has to be conform with guidelines of component and solder paste manufacturer.

The reflow soldering equipment is divided into:
transmission part/heating and welding area/vacuum unit/cooling area and recovery system

1. Transmission part
This structure runs through the whole equipment and is divided into three sections: heating area, vacuum unit and stuffy donkey section. The transport speed of each section is adjusted independently and the width is adjusted as a whole to play the role of transporting PCB board

2. Heating and welding area
The temperature of each temperature zone can be adjusted separately to ensure a flexible temperature curve and stable welding process to meet the requirements of lead-free welding process. During this process, the PCB can meet the requirements of the customer's welding process, which is the same as the standard additional flow welding process.

3. Vacuum unit
At this time, the solder joint of PCB board is in the molten state. The vacuum process is started to make the vacuum pressure as low as 100mbar-10mbar. The internal gas such as pores and cavities can overflow from the solder joint with dynamic melting, and the void rate can be reduced to less than 2%.

4. Cooling area
PCB board from the vacuum unit directly into the cooling area, similar to the standard reflow welding cooling function, meet a certain cooling rate and reduce the temperature of the plate, into the next process, at this time the welding process is completed.

5. Rosin recovery system
With the same function as standard reflow soldering, the rosin is recycled into the specific structure through cooling, regular maintenance, reducing equipment maintenance and environmental pollution.
