PCBA dry ice cleaning machine has the following main applications in semiconductor electronics factory: Dry ice cleaning machine 1Cleaning semiconductor packaging: PCBA dry ice cleaning machine can be used to clean the packaging of semiconductor chips, including wafers, chips, packaging materials, leads, etc. By spraying high-speed dry ice particles, it can effectively remove dirt, grease, solder slag and other impurities on the surface, ensuring the quality and reliability of the package.
2.Cleaning PCB boards: PCBA dry ice cleaning machines can also be used to clean printed circuit boards (PCB boards). During the manufacturing process, there may be solder residues, resin residues, dust, etc. on the PCB, which may cause circuit failure or poor connections. By blasting dry ice pellets, these dirts can be removed efficiently, improving the quality and reliability of PCB boards.
The advantages of PCBA dry ice cleaning machine are as follows:
1.Solvent-free cleaning: PCBA dry ice cleaning machine uses dry ice particles as the cleaning medium, compared with the traditional solvent cleaning method, there is no need to use chemical solvents, avoiding environmental pollution and workers' health risks. At the same time, dry ice can quickly transform into a gaseous state, leaving no residue during the cleaning process.
2.Efficient cleaning: The jet speed of PCBA dry ice cleaning machine can reach tens of meters per second or even higher, and the cleaning efficiency is very high. Dry ice particles expand instantaneously when sprayed, creating impact and heat that effectively washes dirt off the surface.
3.No damage to the surface: PCBA dry ice cleaning machine has a good protective effect on the surface material. Dry ice particles will not cause mechanical damage during the spraying process, nor will they cause harmful effects such as electromagnetic waves and static electricity, and are suitable for cleaning various materials, such as plastics, metals, etc.
4.Energy saving and environmental protection: PCBA dry ice cleaning machine does not need a lot of resources such as water and chemical solvents in the cleaning process, saving energy and material costs. Since dry ice is a renewable resource, it will not cause pollution to the environment and meet the environmental protection requirements of enterprises.
For example, if a semiconductor electronics factory produces wafers, the wafers are often packaged with impurities such as grease and dirt, which can affect the quality of the package. Traditional cleaning methods may require the use of chemical solvents and cannot completely remove dirt. The PCBA dry ice cleaning machine can quickly clean the dirt on the surface of the wafer by spraying high-speed dry ice particles, which not only improves the packaging quality, but also avoids the harm of chemical solvents to the environment and workers.
