Wave soldering is a commonly used soldering method for electronic components, which uses solder melted at high temperature to form a wave-like shape, and is in direct contact with the soldering surface through the wave peak, so as to achieve the purpose of soldering. In the process of wave soldering, the contact between the solder surface and the solder is intermittent and not simultaneous. Normally, the circuit board passes through the wave of solder on the conveyor belt at a certain speed, and the solder only stays on the solder surface for a short time.
The workflow of wave soldering generally includes the following steps:
1.Plug-in: Inserts the electronic components that need to be soldered into the circuit board.
2.Spraying flux: Applying flux to the solder surface in the form of a spray. Flux can improve the quality of the soldering and reduce the thermal shock during the soldering process.
3.Preheating: Preheat the board before wave soldering. The purpose of preheating is to reduce the thermal shock generated when the component enters the wave crest and ensure the stability of the soldering process.
4.Wave soldering: When the board enters the crest, the solder flows in the opposite direction to the direction in which the board is going, which helps to remove the flux around the solder surface and ensures that the solder joints reach the correct temperature to securely solder the components.
5.Cooling: After the welding is completed, the solder joint is completely cooled.
As a commonly used soldering method, wave soldering has the characteristics of high efficiency, stability and reliability, and is widely used in the electronics manufacturing industry. In the wave soldering process, it is necessary to pay attention to reasonable control of the soldering temperature to avoid damage to electronic components caused by excessive temperature, and ensure the soldering quality and product reliability.
