Industrial grade refers to moisture-proof cabinets used in industrial electronic semiconductors and other occasions, mainly used to store MSD devices such as IC and BGA, as well as semiconductors, and easily oxidized materials. The civilian level mainly refers to the storage of civilian items, such as cameras, lenses, documents, antiques, and so on. Compared with industrial moisture-proof cabinets, civil moisture-proof box drying cabinets mainly have low humidity requirements, generally around 40%RH to 50%RH, and the humidity in the box is not too humid. Industrial moisture-proof box drying cabinets are more stringent, generally divided into 20%RH medium humidity moisture-proof cabinets, low humidity moisture-proof cabinets below 10%RH, and ultra-low humidity moisture-proof cabinets below 5%RH.
Industrial moisture-proof cabinets are mainly special equipment for the purpose of moisture-proof storage of components and materials stored in the cabinet by means of creating a low-humidity environment. Its low humidity standards mainly follow the IPC/J-STD-033 standard. In the standard, the components that need to be moisture-proof (called MSD moisture-sensitive components) are classified according to different moisture-proof levels, and the corresponding low-humidity storage requirements are carried out for different moisture-proof levels.
The use of industrial moisture-proof cabinets is also carried out according to the MSD level to select the corresponding humidity. For example, Level 2a/3, use humidity below 10%RH, and Level4/5/5a, use humidity below 5%RH. Below 5%RH, it can play a good moisture-proof effect on all devices. That is the effect of the ultra-low humidity below 5%RH that we mentioned.
The use of moisture-proof cabinets in industry will store more varieties or quantities of devices. In use, there are relatively many times of opening and closing the door. Therefore, the industrial moisture-proof box also needs its fast dehumidification ability, so as to reduce the influence of the door opening and closing of the moisture-proof box.
As mentioned above, industrial moisture-proof cabinets have different capabilities from civil moisture-proof cabinets in terms of low humidity capacity, dehumidification speed, dehumidification performance, etc., and can provide more complete storage solutions for different storage requirements.
