Chengdu Region Technology Co., Ltd

6 Dots Cobalt Free Humidity Indicator Card

Cobalt-free humidity cards do not contain cobalt dichloride and meet environmental requirements.there are manufactured specifically for customers who meet cobalt-free requirements in EU regulations. Before drying is the brown state after moisture is sea blue. It is used to show the sealed space humidity status of the card, it detects whether the humidity in the sealed package is within the safe humidity range the card display percentage, the discoloration can be read out the sealed package is currently the humidity size. Cobalt-free humidity card is widely used in ICs, semiconductors, precision electronic components, precision optics and other high-end electronics, equipment due to the impact of moisture welding, component damage, and other hazards, to avoid electronic components by moisture erosion and damage, according to the IPC-JSTD-O33 moisture-proof standard most products will use moisture-proof packaging combination, and humidity display card is one of the materials of moisture-proof packaging combination.

Description

Cobalt-free humidity cards do not contain cobalt dichloride and meet environmental requirements.there are manufactured specifically for customers who meet cobalt-free requirements in EU regulations. Before drying is the brown state after moisture is sea blue. It is used to show the sealed space humidity status of the card, it detects whether the humidity in the sealed package is within the safe humidity range the card display percentage, the discoloration can be read out the sealed package is currently the humidity size. Cobalt-free humidity card is widely used in ICs, semiconductors, precision electronic components, precision optics and other high-end electronics, equipment due to the impact of moisture welding, component damage, and other hazards, to avoid electronic components by moisture erosion and damage, according to the IPC-JSTD-O33 moisture-proof standard most products will use moisture-proof packaging combination, and humidity display card is one of the materials of moisture-proof packaging combination. Electronic components packaging humidity card into the moisture bag, when the open seal bag can be seen in the bag humidity card percentage value of the discoloration, to determine whether the current humidity in the bag exceeds the humidity threshold should be controlled, such as the percentage value on the humidity card discolored higher than the humidity threshold stored by the device, that is, to dehumidify the components or other treatment, cobalt-free humidity card with desiccant use, the moisture-proof effect is better.

Applications

Humidity cards used in semiconductors and the packaging of high-precision electronic components such as ICs, integrated circuit boards (PCBs), LEDs, optical components, communications electronic sensitive components, organic materials, military products, optical instruments, metal materials, composites, pharmaceuticals, warehousing, and various products

Product standards:

2004/73/EC (EU Environmental Regulations)
GJB2494-95 (Military Standards of the People's Republic of China) ​MIL-I-8835A (U.S. Military Packaging Standard)
EDEC (Electronic Components Industry Federation Standard)

Precautions for use:

Don't be directly in direct contact with metal products, humidity card on the discolored part of the integrated chemical solution, paper for absorbent paper materials. Over time, the chemical solution will penetrate the back, direct contact with the metal easy to cause chemical solution on the product corrosion hazards. Such as placed on the metal product, be sure to use harmless isolation paper to isolate the humidity card from the metal product and choose the back film humidity card.
