Yee HingNitrogen cabinetNitrogen is mainly used to prevent oxidation and moisture. According to the requirements of the application scenario, different control functions can be configured. It is widely used in the R&D and production processes of microelectronics, semiconductors, new energy, national defense, and military industries. It can also be used in chip production processes and advanced SMD packaging technology to prevent moisture-sensitive devices from damp and mildew and prevent components from being reflowed. Popcorn phenomenon. So, does the nitrogen cabinet need to be continuously vented with nitrogen when it is in use? The answer is yes.
The control of nitrogen flow is mainly to maximize the flow. The large flow rate of the nitrogen cabinet can quickly fill the cabinet and achieve the goal of non-oxidation quickly. The oxidation of materials and devices is a cumulative process. When the nitrogen cabinet is opened and closed, the nitrogen concentration in the nitrogen cabinet will decrease. Due to the increase in oxygen content, the oxidation of the material device is proceeding at this time. If the concentration recovery speed of the nitrogen cabinet is too slow, the oxidation process time of the material device will be prolonged. After the nitrogen cabinet is opened and closed for many times, the oxidation of the materials and devices after each opening and closing of the door will accumulate. Over time, the oxidation process of the materials and devices may exceed the permitted range, which may cause abnormal products.
Although the flow meter of the smart nitrogen cabinet makes the nitrogen flow rate adjustable, the consumption of nitrogen has nothing to do with the size of the flow meter. The factors that affect the nitrogen consumption of the smart nitrogen cabinet are the humidity of the external environment, the humidity value set in the nitrogen cabinet, and the length of time to open the nitrogen cabinet and the number of times. So what is the function of the flow meter? The flowmeter can quickly reach the user's set value when it is turned on for a large flow rate, and the time for a small flow rate to reach the user's set value is relatively longer.
The Yihexing intelligent nitrogen cabinet can intelligently control the input and cut off of nitrogen according to the relative humidity or oxygen content in the cabinet. It can be set at one time and controlled automatically to save nitrogen consumption and control costs. The automatic nitrogen intelligent control module can quickly reduce the humidity to below 5%RH, and it only takes about 5-10 minutes to open and close the door. It is suitable for occasions with strict anti-oxidation requirements for frequent door opening and closing.
