Nitrogen making machine The group is applied in the electronics industry: nitrogen is used for encapsulation, sintering, annealing, reduction and storage of electronic products.
It is mainly used in wave soldering, reflow soldering, crystal, piezoelectric, electronic ceramics, electronic copper strips, batteries, electronic alloy materials and other industries. The electronic industry generally requires relatively high nitrogen requirements, usually requiring 99.9% or 99.99% and more than 99.99% nitrogen.
Electronic industry semiconductor and integrated circuit manufacturing process, such as atmosphere protection, cleaning, chemical recovery, etc. Large scale integrated circuits, color TV kinescope, TV sets and radio cassette components, and nitrogen sources for semiconductor components.
In the production process of electronic components and semiconductor components, nitrogen with purity of more than 99.999% must be used as protective gas.
At present, China has used Gao Chundan as carrier gas and protective gas for color TV display tube, large scale integrated circuit, liquid crystal and semiconductor silicon wafer production process. The SMT industry now requires the global manufacturing industry to meet lead-free standards. More and more manufacturers are using the new reflow oven with nitrogen options to respond to the lead-free plan. Because nitrogen atmosphere can prevent oxidation of metal surface during heating. Hong Kai electromechanical The nitrogen solution can ensure the correct activation of flux, reduce the residual amount of some flux, enhance the quality of welding, and make the welding surface more beautiful.
