It is used for packaging, sintering, annealing, reduction and storage of electronic products. It is mainly used in wave soldering, reflow soldering, crystal, piezoelectric, electronic ceramics, electronic copper strip, battery, electronic alloy materials and other industries. The electronic industry generally has high requirements for nitrogen, which usually requires 99.9% or 99.99%, and more than 99.99%.
Atmosphere protection, cleaning and chemical recovery in semiconductor and integrated circuit manufacturing process of electronic industry.
Nitrogen source for processing of large-scale integrated circuits, color television picture tubes, television and radio recorder components and semiconductor components.
In the production process of electronic and semiconductor components, nitrogen with purity of more than 99.999% should be used as the protective gas. At present, China has used high-purity nitrogen as carrier gas and protective gas in the production process of color TV picture tubes, large-scale integrated circuits, liquid crystal and semiconductor silicon wafers.
SMT industry now, the global manufacturing industry must meet the lead-free standard, and more and more manufacturers have used new reflow furnaces with nitrogen options to respond to the lead-free plan. Because nitrogen-based atmosphere can prevent metal surface from oxidation during heating. The gas solution provided by Duer Gas can ensure the correct activation of welding flux, reduce the residual amount of some welding flux, enhance the welding quality, and make the welding surface more beautiful.
