Wave soldering machines are mainly used to solder electronic components onto PCB boards. It forms a specific shaped peak by melting the solder, and when the PCB board passes through this peak, the solder contacts the solder pads and component pins on the PCB board under surface tension and capillary action, thereby achieving soldering.

　　The working process of a wave soldering machine is usually divided into several stages. The first step is the preheating stage, which heats the PCB board to a certain temperature to remove moisture and activate the solder pads. Then, the PCB board enters the wave soldering area, where the solder wave peaks come into contact with the PCB board to complete the soldering. The final stage is the cooling phase, which rapidly cools and solidifies the welded joint.

　　Wave soldering machines have the characteristics of high efficiency and stability. It can quickly complete a large amount of PCB board soldering work, improving production efficiency. Meanwhile, as the welding process is automated, the consistency of welding quality can be ensured. However, wave soldering machines also require regular maintenance and upkeep to ensure their proper functioning. For example, it is necessary to clean impurities in the solder tank, inspect the nozzle and transmission system, etc.

　　When choosing a wave soldering machine, multiple factors need to be considered. Including PCB board dimensions, soldering requirements, production efficiency, etc. Different types of wave soldering machines are suitable for different production needs, so the selection needs to be based on the actual situation.
