With the rapid development of modern technology, the electronics industry has become an indispensable part of people’s daily lives. However, due to the tendency of electronic 

PCBA board surfaces to become easily contaminated, cleaning work has become particularly important. While traditional cleaning methods can remove surface dirt, the chemicals 

used often pose certain risks to the environment and human health. In response to this, dry ice cleaning has emerged as an efficient and eco-friendly cleaning method, becoming 

the preferred choice for cleaning PCBA board surfaces in the electronics industry.

Dry ice cleaning involves using dry ice particles to freeze the dirt and oil on the surface of the contaminants, and then removing them through high-speed jetting. Unlike traditional 

cleaning methods, dry ice cleaning utilizes natural carbon dioxide and does not produce any harmful substances or emissions, resulting in minimal impact on the environment and 

human health. Additionally, the process of cleaning with dry ice particles is also fast, improving cleaning efficiency.

In the electronics industry, cleaning the surface of PCBA boards is crucial. Due to the unique nature of electronic devices, the surfaces are often prone to the accumulation of dust, 

dirt, and other debris. Failure to clean them in a timely manner can negatively impact the proper functioning and lifespan of the equipment. Furthermore, traditional cleaning 

methods often involve the use of chemicals, which can easily leave residues on the surface and have adverse effects on electronic devices.

In contrast, dry ice cleaning is a gentle cleaning method that ensures no damage to the surface of electronic devices. Moreover, as natural carbon dioxide is used, no chemical 

residues are left behind, eliminating any negative impact on the equipment. Therefore, dry ice cleaning is the preferred method for cleaning PCBA board surfaces in the electronics 

industry.

In addition to its application in the electronics industry, dry ice cleaning is widely used in various other industries. For example, in automotive manufacturing, aerospace 

manufacturing, and mechanical manufacturing, dry ice cleaning can be employed to clean various equipment surfaces. Dry ice cleaning not only enhances cleaning efficiency but 

also protects the environment and human health. It can be said that dry ice cleaning is a highly promising cleaning method that will be applied in more industries.
