PCB cleaning methods and the advantages of dry ice snowflake cleaning machines
How to clean PCB after welding, usually there are the following ways1. Wet cleaning
Wet cleaning is a common cleaning method that uses a mixture of chemical reagents and clean water for cleaning. First, soak the circuit board in chemical reagents to remove dirt and residues on the circuit board. Then, rinse the circuit board with clean water to ensure that all chemical reagents are removed. Finally, use compressed air or a fan to blow dry the moisture on the circuit board, but this method will affect the PCB board.
2. Hot melt cleaning
Hot melt cleaning is an efficient cleaning method that uses high temperature and chemical reagents for cleaning. First, place the circuit board in a high temperature environment to remove dirt and residues on the circuit board. Then, use chemical reagents for further cleaning, which is easy to damage the PCB board.
3. Dry ice cleaning
Dry ice cleaning circuit boards is a non-destructive cleaning method that is safer and more reliable than traditional cleaning methods. It can effectively remove dust, grease and other contaminants on the surface of the circuit board while avoiding damage to the circuit board. The advantage of dry ice cleaning is that no chemicals are used. When dry ice comes into contact with dirt and contaminants, it will quickly sublimate and produce strong adsorption force, thereby removing dirt and contaminants from the PCBA board.
Wet cleaning is the most common cleaning method. Although wet cleaning can remove most dirt and residues, it may cause damage to the circuit board. Therefore, if you need to ensure the safety of the circuit board, it is best to choose dry cleaning, which can better protect the PCB board. Our smt pcb processing factory has introduced the latest dry ice cleaning equipment to meet your needs.
4. Advantages of dry ice cleaning circuit boards
Non-destructive cleaning: Dry ice cleaning will not cause mechanical impact or damage to the electronic components and solder joints on the circuit board, avoiding corrosion and damage caused by the use of chemical reagents.
Efficient cleaning: Dry ice cleaning can quickly remove organic matter such as stains and grease on the circuit board, improving cleaning efficiency.
No residue: After dry ice cleaning, organic matter such as stains and grease on the circuit board is completely removed without leaving any chemical residue.
Environmental protection: The dry ice and gas used in dry ice cleaning are non-toxic and harmless substances, harmless to the environment, and meet environmental protection requirements.
5. Scope of application of dry ice cleaning circuit boards
Dry ice cleaning circuit boards are suitable for cleaning various types of circuit boards, including but not limited to printed circuit boards, flexible circuit boards, electronic component welding boards, etc. At the same time, it is also suitable for cleaning circuit boards in various industries and fields, such as aerospace, military, communications, automotive electronics, etc.
Using dry ice cleaning machines instead of PCBA board washing machines is a more environmentally friendly, efficient, safe and energy-saving cleaning method, which can effectively improve production efficiency and reduce production costs. It is a cleaning method worth promoting.
