Clariant has introduced new Humitector type 2 non-reversible humidity indicator cards for SMD dry packing.
The new humidity indicator cards have been developed to maintain the integrity of dry packing, which protects moisture-sensitive devices during shipment or storage.
Humitector type 2 non-reversible humidity indicator cards contain low-halogen and free from cobalt dichloride, a substance of concern to the European Chemical Bureau
Humitector cards are said to be the only low-halogen cobalt dichloride-free humidity indicator cards to combine multiple and reversible color humidity indicators with a patent-pending and non-reversible 60% humidity indicator.
The cards offer verifiable color change accuracy and meet or surpass applicable European Chemical Bureau regulations.
The Joint Electron Device Engineering Council (JEDEC) has approved cards for use in the dry packing standard for surface mount devices.
Clariant cargo and device protection head Michelle Martin said: “Clariant developed Humitector Type 2 non-reversible humidity indicator cards because surface-mount suppliers and device manufacturers said that they wanted greater assurance in the integrity of dry packs for moisture-sensitive devices.
“The 60% non-reversible indicator on these new cards makes it easy to see if the package contents have been exposed to high levels of moisture for a prolonged period of time.”
According to the company, the users of moisture-sensitive and reflowable surface mount devices are having little choice to use humidity indicator cards use in protective packages, as per the J-STD-033 standard.
Clariant Cargo & Device Protection provides a range of desiccants, container desiccants, oxygen absorbers, and humidity indicator solutions, which will allow to protect goods from moisture and oxygen across the entire supply chain.
The company produces these solutions at the manufacturing sites in Brazil, Indonesia, Turkey, the US and China.
Earlier this month, Clariant has introduced Sorb-It Pharma desiccant bags, which can be used for bulk pharmaceutical products.
Sorb-It Pharma desiccant bags, which are filled with silica-gel desiccant, are available in a range of standard sizes such as 50g, 100g, 200g, 250g and 400g.
