Humidity Indicator Cards are designed for use in the packaging of moisture sensitive electronic or electro-optic equipment, or any other humidity-controlled enclosure. They readily detect changes in the humidity of the space being monitored by using a color change indicator which turns from blue to pink as the humidity increases, and turns back to blue when the humidity decreases.
5-10-60% Humidity Indicator Card:
a. 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
b. Complies with the latest revision of the Joint Electron Device Engineering Council IPC/JEDEC standard, J-STD-O33D
halogen and Cobalt dichloride free, a chemical regulated under European Chemical Bureau (ECB) REACH directives
c. Meet or exceed applicable ECB regulations
d. 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.
In order to control humidity levels in sealed packaging, it is necessary to use a Humidity Indicator Card (HIC). These cards are inexpensive and versatile, with the capability of detecting humidity within a number of packaging materials, including MIL Spec (MIL-I-8835). In addition to serving as humidity meters, these cards allow for visual verification of the product and can be used in conjunction with a desiccant.
