Electronic Industry Nitrogen-Making Machine Application

Nitrogen is used for packaging, sintering, annealing, reduction, storage, etc. of electronic products. Mainly used in industries such as wave soldering, reflow soldering, crystal, piezoelectric, electronic ceramics, electronic copper strips, batteries, electronic alloy materials, etc. The electronics industry generally has high requirements for nitrogen, typically requiring 99.9% or 99.99%, and more than 99.99% nitrogen.

In the semiconductor and integrated circuit manufacturing process, nitrogen is commonly used for atmosphere protection, cleaning, chemical recovery, and as a nitrogen source for large-scale integrated circuits, color TV cathode ray tubes, television and cassette components, and semiconductor component processing.

In the production process of electronic and semiconductor components, it is necessary to use ammonia gas with a purity of over 99.999% as a protective gas. At present, countries have applied high-purity nitrogen as a carrier gas and protective gas in the production processes of color TV picture tubes, large-scale integrated circuits, liquid crystals, and semiconductor silicon wafers.

When the air in the pressurized through the purification and drying, Base on Aerodynamics, nitrogen and oxygen in the air in the zeolite molecular sieve (ZMS) on the Pressure swing adsorption  will performance of different diffusion rate through the adsorption of nitrogen. Oxygen in carbon molecular sieve on the surface of the diffusion rate is higher than nitrogen. When the adsorption was not in balance, oxygen was absorbed by carbon molecular sieve in large quantity, and nitrogen was concentrated and enriched in the gas phase to achieve separation of oxygen and nitrogen.
