HICs Address SMD Dry Packing

Claiming to provide more detailed package history than reversible Type 1 indicator cards, Clariant’s Type 2 humidity indicator cards (HICs) with a non-reversible 60% spot indicator are said to be preferred by IPC/JEDEC standards. Groomed for dry packing of surface-mount devices (SMDs), the Humitector Type 2 Non-Reversible Humidity Indicator Cards contain a patent-pending non-reversible 60% humidity spot indicator which enables them to indicate whether dry packed SMDs have been exposed to high levels of moisture at any point during shipment or storage. This offers a major step forward in preventing moisture-compromised surface mounts from entering production.


The HICs provide verifiable color change accuracy and meet or exceed applicable European Chemical Bureau regulations. They have been approved for use by the Joint Electron Device Engineering Council (JEDEC) in the latest revisions to IPC/JEDEC J-STD-033 (J-STD-033D). According to section of J-STD-033D (April 2018), humidity indicator cards cannot be re-used in dry packing if the 60% spot indicates it has surpassed the threshold. The Humitector Type 2 non-reversible 60% indicator will show clearly if this threshold has been exceeded as the permanent colored spot will have migrated beyond its black circle.
