Generally speaking, a semiconductor is a material, of which silicon is the most important element, including germanium, gallium arsenide, silicon carbide, etc. Semiconductor materials are processed into integrated circuits through a series of processes, which are then used in various electronic devices as we know them. Electronic devices closely related to daily activities, such as televisions, computers and mobile phones, are inseparable from the "full help" of semiconductors ". As the demand for electronic devices grows exponentially, the production of semiconductor components is also accelerating. Compressed air, which plays a key role in semiconductor production, is needed in large quantities.
Integrated circuits are extremely sophisticated parts of electronic devices, and a tiny grain of dust may cause the entire circuit to fail. For example, when the circuit board is in the initial manufacturing process, the micro-components are placed on the wafer/circuit board. At this time, these components are not connected to each other, and then compressed air is used to insert (squeeze) the solder into the microscopic holes on the circuit board, and if the compressed air is oily, it will cause damage to the expensive semiconductor components.
Therefore, its production process requires highly specialized technology and a harsh and clean environment. The use of 0 oil-free compressed air is not only a guarantee of high purity in a closed production environment, but also promotes productivity and reduces production losses due to pollution.
General gas quality requirements for semiconductor manufacturing are as follows:
1. Oil requirement 0.00ppm
2. Dust requirement 0.01μm
3. Dew point requirement -40 ℃ to -70 & sh; °C(PDP)
4. Exhaust pressure 0.8-0.85MPa
the main gas points are as follows:
1. Instrument gas
pneumatic components, precision instruments
2. Air separation gas
process protection gas (nitrogen making machine)
3. Process gas
purging, cleaning, cooling, scribing, epitaxy, etching and deposition, ion implantation
sorting, testing, packaging, assembly, packaging, transportation and handling, sewage treatment
The general range of workshop air pressure is usually set between 0.7MPa and 1.0MPa, which is to ensure the normal operation of equipment and processes. For the machining workshop, the pressure requirement of air pressure is generally between 0.5 and 0.7 MPa (MPa), which can meet
Medical air compressor is a special equipment for the hospital to produce clean compressed air, and water lubricated air compressor because of water instead of oil, so that the production of air is more pure, especially suitable for use in hospitals such a place with high air quality requirements, silently guarding the safety of patients.
The air blown by the air compressor can be divided into oil and oil-free. The main difference between them is the oil content in the compressed air. During the compression process of the oil air compressor, the lubricating oil will be in direct contact with the air, so the compressed air will contain a certain amount
The air compressor can be loaded for a long time under normal conditions, but it needs to be judged and adjusted according to the specific usage, environmental conditions and maintenance work. The following is a detailed analysis of this problem: 1. can be added for a long time.
The wide application of medium pressure compressor in all walks of life -- take the water lubricated screw air compressor of Grangelin as an example. In modern industrial production, the medium pressure compressor has become an indispensable part of many industries because of its stable and reliable performance and wide application scenarios.
Permanent magnet variable frequency air compressor is an efficient and energy-saving air compressor type. It combines permanent magnet motor technology and frequency conversion technology to achieve higher energy efficiency and better performance. The following is a brief explanation of the main characteristics and principles of permanent magnet variable frequency air compressor:
In terms of brand selection of power frequency air compressors, there are many well-known brands in the market, such as Shanghai Granklin Group. These brands have advanced production technology and rich experience, and can provide high-quality power frequency air compressors. About Shanghai Granklin Set
When choosing the drain valve of the screw air compressor, the manual drain valve and the automatic drain valve have their own advantages and disadvantages. The specific choice depends on the actual use needs and scenarios. Manual drain valve advantages: lower cost: manual drain valve is usually more economical, suitable for limited budget
The bottle blowing process in the food industry requires strict pressure stability and cleanliness of compressed air. During the bottle blowing process, the compressed air needs to continuously provide uniform pressure to ensure that the wall thickness of the bottle body is consistent and the molding is free of defects, while avoiding the mixing of oil or other impurities, which will affect the food packaging.
Whether the air compressor needs to work 24 hours depends on the specific application requirements and working scenarios. Some application scenarios require a continuous supply of compressed air, which requires the air compressor to run 24 hours a day. For example, some production lines, processes or medical
