Ultrasonic tin lining machine is mainly used for tinning enamelled wires and soldering materials that are difficult to be soldered by conventional methods. Ultrasonic dip soldering is more environmentally friendly and energy saving compared to conventional soldering methods, the ultrasonic vibration and cavitation phenomenon in the dip soldering process is easy for the oxidised layer on the surface of the soldered parts to come off, at the same time, the high frequency vibration energy doesn't melt the solder, which helps to wet the soldered parts with the solder. Because it does not require flux, it saves time and costs for residual flux cleaning, and reduces corrosion to enhance the durability of soldered joints. Provides an environmentally friendly soldering solution that does not use flux and avoids the problems associated with conventional flux soldering, providing stable and reliable soldering.
