Wave soldering operation and setup points

2023-10-24

Wave soldering is a common electronic assembly process, the following are the operation and setup points of Wave Soldering:

1. PCB Preparation: Make sure the PCB surface is clean and free of any dirt, grease or debris. It can be cleaned with a board washer or cleaning solvent.Reflow Soldering

2. Preheating: Place the PCB in a preheating device that can be set for temperature and time in advance. The purpose of preheating is to heat up the PCB and solder paste to ensure that the paste can be completely melted during the soldering process.

3. Solder Adjustment: Adjust the temperature, method and speed of soldering according to the soldering requirements. Usually, solder with lower melting point is used for wave soldering.SMT Machine

4. Wave height setting: According to the welding requirements and component size, set the appropriate wave height. Wave height is too high or too low may lead to unsatisfactory soldering quality.

5. Brush Soldering Flux: Brush the appropriate amount of soldering flux on the wave crest area, the soldering flux helps in the wetting and fluidity of the soldering process.

6. operation parameter settings: set up the wave soldering equipment operating parameters, including preheating time, wave temperature, transfer speed and so on. These parameters need to be set according to the specific welding requirements and component characteristics of the adjustment.

7. component installation: the need to weld the components placed on the PCB, to ensure that the position is accurate.Tin Melting Furnace

8. Wave soldering process: Start the wave soldering equipment and let the wave of solder cover the soldering area of PCB. The solder will automatically make contact with the PCB and components and form a weld.

9. Inspection and Repair: Wait for the end of the soldering process, check the quality of the soldering, if there are problems can be repaired, such as re-strike the soldering iron, replenish the soldering paste and so on.

The above is the general operation and setup points of wave soldering, which may vary according to specific situations and requirements. Before performing wave soldering, it is recommended to read the equipment operation manual in detail and conduct proper practice and training.
