Wave soldering, also known as solder melting, is a soldering method performed on printed circuit boards (PCBs). The basic principle is to achieve bulk welding by contacting the melted solder wave crest to the components on the circuit board. Wave soldering plays an important role in the electronics industry, mainly reflected in the following aspects:

1. improve production efficiency: wave soldering using a perturbation vibration wave superposition technology, can improve the reliability of welding and yield, thus greatly improving production efficiency.

2. Ensure the quality of welding: wave soldering heat source and brazing material and reflow soldering is different, the principle is to use the pump will be liquid brazing material through the nozzle upward spray up to form a 20 ~ 40mm wave, to wave contact with the soldering piece to achieve brazing connection, thus ensuring the quality of welding.

3. Reduce production costs: wave soldering can maintain good thermal conductivity, improve productivity, at the same time, because of its relatively expensive equipment, so to a certain extent, reduce production costs.

4. Adapt to different welding needs: wave soldering system can be classified according to the machine used in different geometric shapes of the wave, so it can be adapted to different welding needs, such as through-hole component welding and surface mount technology welding.

5. Protecting the environment: Modern manufacturing is transitioning from leaded solder to lead-free alternatives, and the use of wave soldering helps to reduce the use of lead and protect the environment.

In conclusion, wave soldering plays an important role in the electronics industry, it can not only improve production efficiency, ensure the quality of welding, reduce production costs, adapt to different welding needs, but also to protect the environment. With the continuous development of the electronics industry, the application of wave soldering will become more and more widespread.
