New nitrogen reflow soldering system


In the soldering process, the reliable connection of electronic components and pads depends on the thermal treatment of solder paste by reflow soldering. Among all kinds of poor soldering, solder wettability, oxidation of sensitive components and improvement of void rate are common problems in SMT process.

Nitrogen shielded soldering technology can significantly improve wettabiliy, reduce void rate, eliminate oxidation and effectively
improve the reliablit of solder joints.


We fully consider all relevant process parameters. For example,when the components are in different temperature curve stages, the heating faced by the solder paste and the oxidation degree of the components are different, so we can design the nitrogen supply in different areas to create a more economical nitrogen solution for you.

Define nitro series furnace is made of stainless steel and adopts a variety of air tightness treatment processes to ensure that the structural tightness of the furnace is not affected by high temperature.

Uniform thermal conductivity and excellent thermal management
Uniform heat conduction performance is the most important realization basis of an excellent reflow soldering system, and it is also a prerequisite to meet the different process requirements of various complex products. Define Nitro series reflow soldering system is equipped with ultra-high thermal conductivity ( \) It can prevent the loss of heat energy caused by the participation of conduction medium, greatly improve the balance of temperature distribution, make the components heated completely and evenly, and provide necessary conditions for the best welding effect. At the same time, the outstanding thermal energy management technology of define nitro can ensure that the temperature in the temperature zone is not disturbed by the adjacent temperature zone, the uniform heating and stable gas flow rate of each component, prevent the shadow effect and monument phenomenon in the welding process, and ensure the best welding effect.

Define nitro is equipped with a special rectifier board, which can ensure that the air flow evenly passes through the PCB board to convey the heat required for welding. Through accurate gas guidance and recyclable hydrodynamics design, the residual flux volatiles in the exhaust in the highly airtight furnace are intensively filtered and recycled to ensure the clean and efficient operation of the furnace.
The gentle temperature rise slope helps to reduce the thermal shock of components, improving the activity of solder paste, and ensuring the solderability of components and PCB solder joints, so as to obtain the minimum △ T and achieve the best welding effect.

Flexible transport systems
For busy and compact production tasks, a reliable transmission system is particularly important to ensure efficiency. This requires not only
safe transmission to meet the process continuity, but also flexible personalized dual track transmission scheme to meet the parallel
production of different products, so as to realize high flexible production process.

Vision Series reflow soldering system follows the design concept of high efficiency and energy saving. Each process section such as
preheating zone, high temperature zone and cooling zone adopts the same temperature zone width, which is convenient for modular
configuration and deployment of process temperature. There is a reasonable spacing between adjacent processes to ensure that adjacent
sections are not disturbed by each other.


Reflow soldering system is an energy consumption step in SMT process. Duing the whole process, how to reduce the impact on the power supply system should be considerated carefully. Vision Series reflow soldering adopts linear heating scheme and full closed-loop algorithm control, which greatly reduces the starting power, reduces the impact of power grid, ensures the stability of system power supply, and greatly reduces the system energy consumption.
Vision series reflow soldering is equipped with a fan drive system with flexible frequency adjustment. According to the requirements of the process window, you can calmly match the adjustable wind speed in each temperature zone, and even the adjustable gas flow rate at the top and bottom of the same temperature zone to ensure uniform and stable air flow.
