Cobalt Free HI Cards
To offer the electronics and semiconductor industries an environmentally friendly Cobalt Free Humidity Indicator (HI) card.
What are they?
Cobalt Free HI Cards provide humidity level indication for dry packaging to electronic and semiconductor manufacturers who desire a card without cobalt.
Why use them?
Many products are highly sensitive to moisture. In order to constantly verify that dry packaging methods are not compromised during storage and tansport of these products, humidity indicator cards allow users along the supply chain to monitor the package conditions.
Indicator spots change from brown to green after exposure to the relavent relative humidity conditions. The cards are reversible and change as conditions change in the packaging environment, allowing users to monitor the conditions of product packaging.
The environmentally friendly Cobalt Free HI cards do not contain cobalt and some configurations can be produced with less than 900 ppm halogen levels where reqired.
Cobalt Free HI Cards are available in all standard configurations and humidity ranges, including indications at 5, 10 and 60 percent relative humidity levels.
Süd-Chemie continues to manufacture a full range of blue-to-pink Cobalt-Dichloride based humidity indicator cards and Cobalt-Dichloride Free HI cards that are also in full compliance with relevant JEDEC standards and ECB regulatory, reporting and labeling requirements.
Product characteristics :
Cobalt Free Humidity Indicator Cards are free of Cobalt, a chemical which has classification and labeling requirements under the European Chemical Agency (ECHA) REACH directive.
Meets all relevant ECB/REACH labeling requirement.
Typical applications include the dry packaging of semiconductor and electronic device.
Most conifgurations offer less than 900 ppm Halogen level.
