    Independent detection of oxygen concentration in the whole process
    The nitrogen quantity in the whole process can be controlled, and each temperature zone can be controlled in an independent closed loop, so that the oxygen concentration range can be controlled within 50-200 ppm. When the oxygen concentration in the whole process is within 200ppm, the nitrogen consumption is: 22-25m ³/ H ( 12
    temperature zone); When the oxygen concentration in the welding area is within 1000ppm, the nitrogen consumption is 10-12m ³/ H ( 12 temperature zone).
    Practical significance of whole-process hypoxia concentration control
    Inert protection shall be provided throughout the process to prevent secondary oxidation of the welding interface; Poor wetting caused by oxidation will lead to more fatal hazards in the process of miniaturiza- tion and close spacing. Increase the width of lead-free welding process window and make process commissioning more flexible; In nitrogen environment, the surface tension of liquidsolder decreases, which can effectively reduce
    the peak temperature and shorten the reflow time.
