Semiconductor equipment requires extremely high quality of compressed air to ensure the cleanliness of the production environment, the stable operation of the equipment, and the quality and yield of the final product. Specifically, semiconductor equipment has strict requirements on the dust content, residual oil content and dew point temperature of compressed air.
semiconductor equipment requires that the particulate matter content in the compressed air must be very small to ensure the cleanliness of the production environment and avoid product pollution. Typically, the particulate concentration is required to be less than 100 pb/ft3 or even lower. In high-end applications, such as chip manufacturing, the control of dust particles is more stringent, requiring that the size of dust particles should be less than or equal to 0.1 μm to ensure that the air does not contain large particles of dust.
the oil in the compressed air will pollute the semiconductor equipment and affect the quality and performance of the product. Therefore, semiconductor equipment has very strict requirements on the oil content in the compressed air. Generally speaking, the total oil content is required to be less than 1ppm (one part per million), and even in some high-end applications, it is required to use 0-grade oil-free compressed air to completely eliminate the risk of oil pollution. Low oil content can ensure the quality of the product and the smooth progress of the production process.
dew point temperature is an important index to measure the moisture content in compressed air. Semiconductor equipment requires that the dew point temperature of compressed air must be much lower than the ambient temperature to prevent the generation of condensed water in the air supply system, thereby affecting the stable operation of the equipment and the quality and stability of the product. Generally, high-end applications such as chip manufacturing require dew point temperatures below -70°C, and even lower requirements, such as -80°C, -110°C or even -120°C. The strict control of the dew point temperature helps to maintain the stability and reliability of the product.
in summary, semiconductor equipment has strict requirements on the dust content, residual oil content and dew point temperature of compressed air. These requirements are directly related to the cleanliness of the production environment, the stable operation of the equipment, and the quality and yield of the final product. In order to ensure that the quality of compressed air meets the standards, semiconductor equipment manufacturers usually carry out strict inspection and maintenance of compressed air, and adopt efficient air purification equipment and filtration systems to ensure that the quality of compressed air continues to meet production requirements.
The oil content of compressed air in ordinary air compressor room is usually in the range of 3~5 mg/m, while the production line that requires the quality of air source will press this value to 0.01 mg/m or even lower through oil-free water lubrication air compressor or precision oil removal equipment at the rear end. When selecting the type, the actual demand of the gas end should be clearly defined, and then the equipment should be matched, so that the oil content will not be wasted.
To judge whether the air compressor is oil-containing or oil-free, you can consider the following aspects: First, you can refer to the product manual or technical specification sheet of the air compressor. These data are usually clearly marked whether the air compressor is oil-containing or oil-free. by reading carefully
Screw air compressor has a wide range of applications in the field of metallurgy, mainly used in the following aspects: drive pneumatic tools: metallurgical production line need to use a variety of pneumatic tools, such as percussion drill, pneumatic wrench. The air source provided by the screw air compressor can be driven
Oil-free air compressors, especially screw air compressors, Grantklin's water-lubricated oil-free air compressors, use variable frequency motors to achieve energy saving and emission reduction, and monitor the automatic operation status of air compressors through panels. The use of variable frequency motor, automatic control system, through variable frequency soft start: eliminate the peak current when starting, avoid the impact of the power grid, through the step-by-step speed adjustment to avoid the impact of current, improve flexibility.
View detailsOil-free air compressors do not need to be refueled. The water-lubricated air compressors produced by Granklin Group are 100% free of oil. However, our atmosphere contains certain oil and gas, particulate matter, etc., so in the post-equipment processing process, precision filters are still needed.
To deal with the problem of water content in the air compressor gas, the following methods can be adopted: 1. installation and regular inspection of the drain valve at the bottom of the cooler drain valve: a drain valve is usually arranged at the bottom of the air compressor cooler. Once you find water inside the air compressor, you should immediately
Q: Does the general air compressor have oil? A: Yes. The most common is the piston air compressor, this air compressor everywhere has compressed gas oil content is very large. There are more screw air compressors used in factories, and screw air compressors are divided
Air compressors are extremely versatile in factories and are called "general machinery" and are widely used in various industrial scenarios. The following is a specific analysis: 1. the core value of air compressors Air compressors provide power or gas source for equipment through compressed gas, which is second only to electricity.
Whether the cold dryer (freeze dryer) needs to work continuously for 24 hours depends on the operation mode of its supporting equipment (such as air compressor), the stability of gas demand and the requirements of the process on the quality of compressed air. Operation of a combined oil-free or water-lubricated air compressor
In the food industry, the quality of compressed air has a crucial impact on product safety and quality. Therefore, it must be ensured that the compressed air used for food production reaches a certain sterilization level. The following is a letter related to the level of compressed air sterilization of food.
