The intelligent nitrogen cabinet mainly uses nitrogen to reduce humidity and prevent oxidation. The nitrogen moisture-proof cabinet has no fan, no noise, no moisture return, no frost, no thermal effect, and stable dehumidification effect. The more nitrogen is charged, the humidity will also decrease. The lower the yield, the better the anti-oxidation effect. The nitrogen cabinet is mainly used to store IC, semiconductor devices, silicon wafers, electronic components and other items. So, what should be paid attention to when using the nitrogen cabinet? ?
The precautions for nitrogen cabinets include the selection and use of nitrogen cabinets. The selection of nitrogen cabinets mainly requires attention to the control of nitrogen flow, the detection of nitrogen concentration, nitrogen control, scalability and anti-static.
The control of nitrogen flow is mainly to make the flow as large as possible. The large flow of the nitrogen cabinet can quickly fill the cabinet, and can quickly achieve the purpose of no oxidation. The oxidation of materials and components is a cumulative process. When the nitrogen cabinet opens and closes the door in the process , the nitrogen concentration in the nitrogen cabinet will decrease. Due to the increase in oxygen content, the oxidation of the material device is in progress at this time. If the concentration recovery rate of the nitrogen cabinet is too slow, the oxidation process time of the material device will be prolonged. After several times of opening and closing the door of the nitrogen cabinet, the oxidation of the materials and components after each door opening and closing will accumulate. In the long run, the oxidation process of the materials and components may exceed the permitted range, resulting in abnormal products.
In use, the main precautions for the use of nitrogen cabinets are to pay attention to the control of door opening and closing time and door opening and closing frequency. The shortening of door opening and closing time can effectively reduce the loss of nitrogen and maintain the nitrogen concentration in the cabinet. The reduction of door opening and closing frequency Oxidation build-up in material devices can be minimized. These measures are methods that can really have a significant impact on storage performance.
