Semiconductor test plant compressed air dryness
in a semiconductor test plant, the dryness of the compressed air is a crucial parameter. Since semiconductor devices are extremely sensitive to moisture and other contaminants in the environment, highly dry compressed air must be used to ensure the reliability of testing and production processes. Generally speaking, the semiconductor industry has very low requirements for the dew point of compressed air, usually at -40 ℃ ~-70 ℃ or even lower. This is to prevent the formation of condensation water on the semiconductor surface, thereby avoiding the risk that may cause equipment failure or product quality problems.
In order to meet this requirement, semiconductor test plants are usually equipped with special compressed air drying equipment, such as refrigeration dryers, adsorption dryers, etc., to further reduce the moisture content in the compressed air. At the same time, the choice of air compressor is also particularly important. It is necessary to ensure that the compressed air produced by it has sufficient dryness and purity.
Application of Air Compressor Products of Shanghai Granklin Group in Semiconductor Enterprises
as a professional air compressor manufacturer, Shanghai Granklin Group has a wide range of applications in semiconductor companies. In particular, its water-lubricated air compressors and oil-free air compressors play an important role in semiconductor testing and production processes due to their ability to produce compressed air with high purity and low dew point.
Water-lubricated air compressor: The water-lubricated air compressor uses water as a lubricant to avoid the problem of oil pollution. At the same time, through the precise filtration and drying system, the moisture and impurity content in the compressed air can be further reduced to meet the demand of the semiconductor industry for high-purity compressed air. In semiconductor companies, water-lubricated air compressors are often used to provide power, purge, and clean equipment.
Oil-free air compressor: Oil-free air compressor does not use lubricating oil in the compression process, so it can produce completely oil-free compressed air. This is critical for the semiconductor industry, as even trace amounts of oil can cause damage to semiconductor devices. Oil-free air compressors are usually equipped with high-efficiency filtration systems to ensure that the purity and dryness of the compressed air meet the requirements of the semiconductor industry. In semiconductor companies, oil-free air compressors are widely used in various occasions that require high-purity compressed air, such as pneumatic transmission, vacuum pump drive, chemical vapor deposition (CVD) and other processes.
In short, the water-lubricated air compressors and oil-free air compressors of Shanghai Grankering Group play an important role in semiconductor enterprises with their excellent performance and reliability, providing stable and high-purity compressed air support for semiconductor testing and production processes.
0.01 g/m & sup3; The moisture content of the air coming out of the cold dryer is usually not more. However, please note that the air outlet pressure dew point of the cold dryer is 2~10 ℃ at 0.7 Mpa, which is equivalent to the atmospheric pressure dew point of -23 ~-16 ℃, and the water content at this time is about 0.82~1.48 g/m & sup3;.
Q: frequency conversion air compressor and frequency air compressor difference? A: compared to the frequency air compressor, variable frequency air compressor pressure is more stable, the current is more stable. The most energy-saving variable frequency air compressor belongs to the permanent magnet variable frequency air compressor using permanent magnet motor, which reduces the energy consumption.
