In the process of wave soldering, the soldering zone will produce high temperature, and the solder will melt and start to flow at high temperature, and the oxygen in the air will react with the solder, resulting in an oxide layer on the surface of the solder and the solder joint, which will have a negative impact on the soldering quality.

    Nitrogen is used as a protective gas in the wave soldering process, which can form a gas protective layer around it. Nitrogen is an inert gas that can effectively isolate oxygen and water in the air to prevent oxygen oxidation of solder and solder joints during soldering, thereby reducing solder joint defects. In addition, nitrogen has excellent thermal conductivity and better fluidity of the solder, which can improve the wettability of the solder joint and reduce the generation of bubbles, thus obtaining a smoother and more polished solder joint.

    The use of nitrogen in the wave soldering process is essential to improve the soldering quality and increase the reliability of the product, especially for the soldering of high-density, high-reliability and small components. In response to this demand, Suneast Technology's independent research and development of "tunnel type full sealing nitrogen wave soldering" came into being!

    Suneast Technology PERFECTFLOW series of tunnel full sealing nitrogen wave soldering adopts the world's first soldering zone sealing solution and innovative segmented transmission scheme to solve the problems of conventional tunnel wave soldering segment conveying plate, width adjustment lag and inconvenient operation and maintenance. The bad influence of the large drop between the wave crest and the tin surface is eliminated, and the application effect of the nitrogen protection process of the wave crest soldering is brought to the extreme, which greatly improves the performance of the tunnel wave crest soldering equipment and the quality of the soldering process.
