A, SMT industry application nitrogen reflow and wave soldering, with nitrogen can effectively restrain the oxidation of solder welding, improve the wettability, accelerate the wetting speed reduce solder bridging, avoid, reduce welding defects, get good welding quality. Using nitrogen purity greater than 99.99 or 99.9%.
Two, semiconductor silicon industry application of semiconductor and integrated circuit manufacturing process of atmosphere protection, cleaning, chemical recycling, etc.. The manufacturing for special PSA nitrogen making machine of semiconductor silicon industry, successfully replaced the liquid nitrogen, the system has been running in Hongkong without a break.
Three, the semiconductor packaging industry application of nitrogen packaging, sintering, annealing, reduction, storage. The PSA nitrogen making machine to assist industry major manufacturers to win the initiative in the competition, can effectively enhance the value of. Four. Nitrogen selective welding, purging and packaging for electronic components industry. Scientific nitrogen inert protection has proven to be an essential part of the successful production of high quality electronic components
