What are the requirements for compressed air in the electronics industry?

In the electronics industry, compressed air plays an important role, but it also needs to meet certain quality requirements, including the following aspects:

compressed air must be dry and dust-free: In the production process of electronic products, tiny dust particles may have a negative impact on the performance of the product. Therefore, compressed air must be efficiently filtered to ensure that it is dust-free. In addition, due to the sensitivity of electronic products to humidity, compressed air also needs to be fully dried.

Low oil content in compressed air: In the production of electronic products, if the compressed air contains oil, it will not only affect the product quality, but may also cause the failure of production equipment. Therefore, the oil content of compressed air needs to be strictly controlled.

Pressure stability: The electronics industry has certain requirements for the pressure of compressed air, and it is necessary to ensure the stability of the pressure to prevent problems in the production process.

Specifically, some advanced electronic industry applications may need to use compressed air of 2-1-1 grade under ISO8573-1 standards, I .e. compressed air is below dew point temperature -20 ℃, dust particle size is not more than 0.1um, oil content is not more than 0.01 mg/m & sup3; and other standards. In some semiconductor, chip and other industries, it may be necessary to use more stringent compressed air quality levels, such as oil-free compressed air.

In order to meet these standards, the electronics industry usually installs various types of purification devices in compressed air systems, such as pre-air storage tanks, post-air storage tanks, precision filters (pre-filtration, pre-filtration and fine filtration) and dryers. Through the combination of these purification devices, the impurities in the compressed air, such as oil, moisture, solid particles, etc., can be effectively removed to ensure the purity and stability of the compressed air, so as to meet the high-quality requirements of the electronics industry for compressed air.
