Humitector™ Type 2 Non Reversible Humidity Indicator Card
To help assure integrity of moisture sensitive surface mount devices in a dry pack environment
Humitector™ Type 2 non-reversible humidity indicator card
- 60% non-reversible indicator spot provides a clear permanent visual signal that moisture sensitive surface mount devices have been exposed to humidity for a prolonged period of time
- Complies with the latest revision of the Joint Electron Device Engineering Council IPC/JEDEC standard, J-STD-O33D
- Low-halogen and Cobalt dichloride free, a chemical regulated under European Chemical Bureau (ECB) REACH directives
- Meet or exceed applicable ECB regulations
- Easy to use with typical applications of dry packing (humidity indicator card, desiccant, moisture barrier bag, moisture sensitive label) of moisture sensitive surface mount devices - MSDs, SMDs
JEDEC - Humidity Indicator Cards
The Humitector™ Type 2 non-reversible humidity indicator card (HIC) provides verifiable color-change accuracy, as required by the Joint Electron Device Engineering Council IPC/JEDEC standard J-STD-033D, Handling, Packing, Shipping and Use of Moisture/Reflow and/or Process Sensitive Devices. Humitector Type 2 non-reversible humidity indicator cards are low-halogen, free of cobalt dichloride, and meet or exceed applicable European Chemical Bureau (ECB) regulations.
The use of Type 2 HICs with a non-reversible 60% spot indicator is preferred by IPC/JEDEC standard J-STD-033D.

To control damaging moisture and ensure that reflowable components and subassemblies can be safely and reliably assembled, the J-STD-033D standard specifies that devices be "dry packed" or "dry pack" for storage or shipment. Typically, dry packing consists of the surface mount device (SMD) packages in their protective packaging: tube (sticks, magazines), tape and reel, or tray, a humidity indicator card, desiccant, moisture barrier bag, and a moisture-sensitive label.
- ball grid arrays (BGAs)
- capacitors and resistors
- light-emitting diodes (LEDs)
- plastic leaded chip carriers (PLCCs)
- quad flat packs (QFPs)
- small outline integrated circuits (SOICs)
- transistors and diodes
When used in these dry pack configurations, the Humitector Type 2 non-reversible humidity indicator card can help provide complete proof of dry pack integrity, an assurance that moisture sensitive contents have not been exposed to high humidity for a prolonged period at any time during packaging, storage or transport. Conversely, if package contents are exposed to high levels of relative humidity, the blue color contained in the non-reversible, 60% indicator provides a clear and permanent visual signal, spreading outside of the black indicator circle that surrounds it.
Traditional vs. Type 2 Humidity Indicator
Thanks to its non-reversible indicator, the Humitector Type 2 card helps provides a complete history of the dry pack environment. Conventional humidity indicator cards, with only reversible indicators, reflect only current (dry or humid) conditions. If products are exposed to damaging humidity for a prolonged period but are returned to a dry environment before the card is checked, such damage could go undetected.
Further, per section 18.104.22.168 of J-STD-033D (April 2018), HI cards cannot be
re-used in dry packing if the 60% spot indicates it has surpassed the threshold. With the Humitector Type 2 cards non-reversible 60% indicator, one can easily see if the threshold has been surpassed by the permanent colored spot migration beyond its black circle.
