2. Water cleaning Technology

Water cleaning technology is the future development direction of cleaning technology. It is necessary to set up pure clean water source and discharge water treatment workshops. It uses water as the cleaning medium and adds surfactants, additives, corrosion inhibitors, chelating agents, etc. to the water to form a series of water-based cleaning agents. It can remove water solvents and non-polar contaminants. 3. No-clean technology: During the welding process, no-clean flux or no-clean solder paste is used. After welding, the product directly enters the next process without cleaning. No-clean technology is currently the most widely used replacement technology, especially for mobile communication products, which basically adopt the no-clean method to replace ODS. 4. Solvent Cleaning Technology: Solvent cleaning mainly utilizes the dissolving power of solvents to remove contaminants. Solvent cleaning is adopted because of its fast evaporation and strong dissolving ability, so the requirements for equipment are simple. After we have chosen the corresponding cleaning technology, how should we use the ultrasonic cleaner for cleaning? 1. Put the circuit board that needs to be cleaned into the ultrasonic cleaning tank. Then add plate washing water or solvent until the areas that need to be cleaned are fully submerged. 2. Connect the power supply of the ultrasonic cleaner to the power source, turn on the power-on switch, start the ultrasonic switch, set the working time. For mechanical control, it is generally adjustable from 0 to 20 minutes or always on. For digital control, the working time can be directly set. The circuit board can be cleaned for 1 to 5 minutes. It depends on your specific cleaning needs. After setting the ultrasonic working time, wait for 1 to 5 minutes after the ultrasonic cleaner starts working. The ultrasonic cleaner will automatically stop working. If you have the constant on function of the ultrasonic cleaner or it is working for a long time, just bring the motherboard you want to clean directly. 4. At this point, when looking at the various stains on the circuit board, it turns out that they have been cleaned thoroughly. The alcohol and board cleaning water can be reused. This is the ultrasonic cleaning machine. It's simple, fast and environmentally friendly.
