Humidity indicator (HIC)

1, Introduction:

   humidity indicator  (HIC) is a card on which a moisture-sensitive chemical is impregnated such that it will change color when the indicated relative humidity is exceeded. This item is an inexpensive way to quantify relative humidity levels inside sealed packaging. They are available in many configurations and used in many applications, especially military and semiconductor.

   The most common humidity indicator cards change color from blue (less than indicated RH level) to pink (greater than indicated RH level). The base chemical is cobalt(II) chloride. United States Military Specification Mil-I-8835A is the governing specification for a humidity indicator card. The humidity indicator card is also specified for use in J-STD-033 which is the standard for Handling, Packing, Shipping and Use of Moisture/Reflow Sensitive Surface Mount Devices, also known generically as semiconductors. This is a joint standard developed by the Joint Electron Device Engineering Council and IPC and is used in semiconductor packaging.

2, Specification:

   humidity indicator : one dots, three dots, four dots, six dots

    RH 8%, 5%-15%,5%-60%,10%-40%,10%-60%..............

3, Application

    PCB, IC, LED, Semiconductor, electronic packaging, optical components, optical equipment packaging

    Matel products, electronic components.......

4, Packing

   250pcs/ can, 3000pcs/carton

humidity indicator  is often used with desiccant bag and MBB, to ensure that all the products inside the sealed packagings are in safe condiction.
