The semiconductor industry has very strict requirements for compressed air, because compressed air is directly in contact with the product, and its quality and purity directly affect the quality and performance of the product. The following are the main requirements for compressed air in the semiconductor industry:
particle control: Due to the high precision of semiconductor products, tiny particle contamination can lead to product failure. Therefore, the concentration of particulate matter in the compressed air is required to be very low, usually less than 100 per cubic foot (or less) to ensure the cleanliness of the production environment and the quality of the product.
Humidity control: Humidity also has a great influence on semiconductor products. Excessive humidity may cause problems such as moisture and corrosion. Therefore, the humidity in the semiconductor compressed air must be strictly controlled, and the relative humidity is usually required to be lower than 50% to prevent the product from being affected by moisture.
Oil control: The oil in the compressed air will pollute the semiconductor products and affect the quality and performance of the products. Therefore, the oil content in the compressed air is required to be very low, and the total oil content is usually less than 1ppm or even lower. Some high-end applications, such as chip manufacturing, even require the use of 0 oil-free compressed air.
Gas purity: In addition to particulate matter, humidity and oil, the semiconductor industry also requires compressed air to have a certain degree of gas purity. This is mainly to prevent other gas components from polluting the product or affecting the performance of the product. Generally speaking, the purity requirements of nitrogen, oxygen and other gases are relatively high.
In order to meet these requirements, the semiconductor industry usually uses multi-stage filtration, drying and purification processes to ensure that the quality and purity of compressed air meet production requirements. At the same time, the production, transportation and use of compressed air will be strictly monitored and managed to ensure the stability and reliability of compressed air.
6kg of compressed air usually refers to a pressure of 6kg force per square centimeter (kgf/cm²), which is equivalent to about 0.6 MPa or 6 bar. The following is the detailed unit conversion process: 1. basic concept kilogram force per square centimeter (kgf/cm²): Representation
The range of pressures that an air compressor can reach depends on the specific compressor type and design. In general, the common air compressor pressure range from a few bar to a very high several hundred bar are possible. The following is the general pressure of different types of air compressors
Oil-free air compressor and oil-free air compressor have their own advantages and disadvantages, which is better depends on the specific application scenarios and needs. The advantages of the oil air compressor mainly include: higher work efficiency: due to the effect of oil lubrication, the oil air compressor is aging at work
The standard specifications for oil-free screw air compressors cover many aspects, including air quality, energy efficiency certification, energy-saving technical requirements, and local energy efficiency standards. The following is a detailed summary of these standard specifications: 1. Air Quality Standard ISO 8573-1: This is
In the field of compressed air equipment, single-screw air compressors and twin-screw air compressors have their own advantages, and the water-lubricated single-screw air compressors produced by Shanghai Granklin Group stand out with their unique advantages. Single screw air compressor with its simple structure, simple maintenance
The replacement cycle of the three filters of the air compressor can be determined according to different filters and specific usage. The following are some general guidelines: Air filter: Non-original general use time is 2000 hours, but it can be based on actual air quality and
During the operation of the air compressor, condensed water will be generated from the compressed air, which needs to be discharged regularly to maintain the performance of the equipment and the quality of the compressed air. The specific drainage frequency shall be comprehensively judged in combination with the operating environment and the operating state of the equipment: if the ambient humidity is high and the equipment continues to operate
Whether the air compressor is equipped with backup equipment depends on the specific application scenario and needs. The following is a detailed analysis of this issue: The importance of 1. air compressors Air compressors are indispensable key equipment in many industrial and commercial applications. It
The main difference between oil-free air compressors and oil-free air compressors is reflected in their working principle, use environment and maintenance requirements. The following is a detailed comparison between the two: Working principle: Oil-free air compressor: This type of air compressor does not need to be used when running
Question: How long is the air compressor maintenance cycle? Answer: Air compressor maintenance is often said to be screw air compressor, screw air compressor because of the gas production is sufficient to run stable and widely used by enterprises. Daily inspection, monthly inspection, annual inspection, more inspection and maintenance can effectively extend
