Most high-end electronics, instruments, and equipment, such as electronic components and precision optics, are highly susceptible to moisture, resulting in rust, reduced sensitivity, and even irreversible damage to products. Most products of finished and semi-finished products in the packaging phase will use a moisture-proof packaging combination to protect the product. The humidity indicator card is a simple, inexpensive material that quickly detects whether humidity is under control. When the sealed bag is opened, the data read by the color display on the humidity card can be used to monitor the humidity in the sealed package is within the specified humidity range. At the same time, it can indirectly reflect whether the desiccant in the sealed packaging plays a role in moisture absorption. Finally, the user can get the effectiveness of the desiccant or evaluate the packaging method
Humidity indicators are used to detect moisture and humidity in packaging, including moisture and metal barrier bags.
The composition consists of cobalt dichloride-free on cardboard.
The color on the card changes to indicate the RH level in the package.
The humidity indicator card complies with IPC/JEDEC 033.
Cobalt dichloride-free cards comply with RoHS, REACH, and WEE directives regarding hazardous substances
Cobalt dichloride is a toxic chemical substance that changes color when exposed to changing moisture storage levels and is commonly used for HIC for this purpose. Cobalt dichloride is a chemical regulated by the European Chemical Bureau (ECB) REACH and had been identified as a substance of environmental concern. Therefore, there is no cobalt dichloride HIC. Propose IPC/JEDEC J-STD-0.33 to electronics and semiconductor manufacturers. Complain about a humidity card that does not contain cobalt dichloride and complies with the European Union and the evolving hazardous substances directive
