The electronics industry is used for packaging, sintering, annealing, reduction, storage of electronic products. Mainly used in wave soldering, reflow welding, crystal, piezoelectric, electronic ceramics, electronic copper strip, battery, electronic alloy materials and other industries. The electronics industry generally has high nitrogen requirements, usually requiring 99.9% or 99.99%, and 99.99% or more of nitrogen. Atmosphere protection, cleaning, chemical recycling, etc. for semiconductor and integrated circuit manufacturing processes in the electronics industry. Nitrogen source for processing large scale integrated circuits, color TV kinescope, TV and radio recorder components and semiconductor components. In the production process of electronic components and semiconductor components, nitrogen with a purity of more than 99.999% needs to be used as a protective gas. At present, high purity nitrogen has been used as carrier gas and protection gas in the production process of color TV picture tubes, large-scale integrated circuits, liquid crystals and semiconductor silicon wafers. SMT Industry Now that the global manufacturing industry must meet lead-free standards, more and more manufacturers are responding to the lead-free program by using new reflow furnaces with nitrogen options. Because the nitrogen-based atmosphere prevents the metal surface from oxidizing during heating. Durr Gas provides gas solutions to ensure the correct activation of flux, reduce the residual amount of partial flux, enhance welding quality, and make the welding surface more beautiful.
