Wave soldering is a common surface assembly technology, mainly used for soldering through molten solder waves. During the wave soldering process, the following key parameters need to be strictly controlled:
1. Wave crest temperature and height: During the wave soldering process, the solder is evenly heated to a molten state in the wave crest, and then the solder is applied to the PCB pad through the movement of the wave crest to achieve a soldering connection. Make sure that the temperature and height of the wave crest are moderate to ensure that the solder melts evenly and fully, while avoiding overheating or underheating.
2. Wave crest speed and time: The wave crest movement speed and time on the PCB pad also need to be precisely controlled to ensure that the solder is fully applied to the PCB pad and form a good solder connection. Too fast speed may cause uneven soldering, and too slow speed may cause excessive soldering or incomplete solder solidification.
3. Pad surface condition: Before wave soldering, it is necessary to ensure that the surface of the PCB pad is clean, flat and well coated to ensure that the solder can be effectively applied and form a stable solder connection.
4. Solder selection: In the wave soldering process, it is also very important to choose the right solder. The commonly used wave soldering solder is mainly solder alloy, such as Sn63Pb37, etc., and the appropriate solder model and composition can be selected according to specific requirements.
5. Stability of welding equipment: The stability and accuracy of wave soldering equipment also play a vital role in the welding quality. Therefore, it is necessary to ensure the stability and accuracy of the welding equipment, and perform regular maintenance and calibration of the equipment.
By strictly controlling the above key parameters, the stability and consistency of the welding quality during the wave soldering process can be ensured, thereby ensuring the reliability and stability of the welding connection. At the same time, timely quality inspection and control of the welding process can avoid the occurrence of unqualified welding quality due to improper welding parameters.
