Specialized Nitrogen Generator For Smt Industry

Now, the global chip manufacturing industry must meet lead-free standards, and more and more manufacturers are using new reflow soldering furnaces with nitrogen options to respond to lead-free plans. Because a nitrogen based atmosphere can prevent the oxidation of metal surfaces during heating. The gas solution provided by our company can ensure the correct activation of solder flux, reduce the residual amount of some solder flux, enhance the welding quality, and make the welding surface more beautiful.

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.
