Humitector™ Type 2 Non Reversible Humidity Indicator Card

To Help Ensure Integrity of Moisture Sensitive Surface Mount Devices in A Dry Pack Environment

The Humitector Type 2 Humidity Indicator Card, used together with a Desi Pak® desiccant, can help to provide a complete history of a dry pack environment for moisture sensitive surface mount devices (SMD’s) (MSD – moisture sensitive device). It complies with IPC / JEDEC standard, J-STD-033D. Humitector Type 2 is low halogen and cobalt dichloride free.

Features

BENEFITS

  •  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
  • Meets or exceeds 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.

 

DRY PACKING

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.

Examples of SMD packages and technologies include:
  • 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 3.3.2.3 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.
