What is wave soldering? What are the advantages of wave soldering process?
Wave-crest welding is a complex process, if any link error will affect the quality of wave-crest welding. So, what is wave welding and what are the advantages of wave welding process?

1. What is wave soldering
Wave soldering refers to the molten solder (lead-tin alloy), which is sprayed by an electric pump or electromagnetic pump into a solder wave as required by the design. It can also be formed by injecting nitrogen into the solder pool, so that the pre-installed components are printed. The board passes through the solder wave crest and forms a solder peak of a specific shape on the solder liquid surface. The PCB loaded with components passes through the solder wave crest at a certain angle and a certain immersion depth to realize the soldering process of the solder joint. called wave soldering.
Second, the advantages of wave soldering process
1. Save labor and materials, improve production efficiency and reduce production costs.
2. The circuit board has a short contact time with high-temperature soldering, which can reduce the warpage and deformation of the circuit board.

3. Eliminate the interference and influence of human factors on product quality, and improve the quality and reliability of solder joints.
4. The solder of the wave soldering machine is fully active, which is conducive to improving the quality of the solder joints.
5. Due to the use of a good exhaust system, the operating environment and the operator's physical and mental health are improved.
6. The anti-oxidation meter on the surface of the molten solder is isolated from the air. As long as the solder wave is exposed in the air, the opportunity for oxidation is reduced, and the waste of solder caused by oxide slag can be reduced.
7. The consistency is good, which ensures the consistency of product installation quality and the standardization and standardization of process.
8. Can do things that cannot be done manually.
