There are five methods for welding the dimming control board, and each method has different advantages.

　　1. Manual welding of dimming control board, manual welding is suitable for product trial production, small batch production of electronic products, debugging and maintenance of electronic products, and some occasions that are not suitable for automatic welding.

　　2. The characteristics of dip welding and dip welding of the dimming control board: simple operation, no leakage of welding, and high production efficiency; but it is easy to cause defects such as virtual welding, and it is necessary to correct the solder joints; improper control of the welding bath temperature will lead to printing The board is lifted and deformed, and the components are damaged. This project has high requirements on welding tools, and it is not economical for students to learn.

　　3. The characteristics of wave soldering and wave soldering of dimming control board: high production efficiency, most suitable for mass soldering of single-sided printed circuit boards; soldering temperature, time, amount of solder and flux, etc. can be well controlled.

　　However, wave soldering is prone to solder joint bridging that needs to be corrected. This program has high requirements on welding tools, and it is not economical for students to learn.

　　4. Reflow soldering of dimming control board, this technology is mainly used in the soldering of SMD components.

　　5. Contact welding of the dimming control board. This solution is more practical for cable connection terminals and other occasions, but has no practical value for welding radios, and is not economical for students.
