Humidity Indicator Cards and Desiccant: Product Selection Guide
SCS Humidity Indicator Cards (HIC) are printed with moisture sensitive spots which change color from blue to pink when
exposed to a relative humidity level. The HIC is typically used with Desiccant inside a Moisture Barrier Bag to protect static
and moisture sensitive components noting the highest relative humidity level exposure. SCS manufactures Moisture Barrier
Bags with different laminates having different moisture vapor transmission rates. SCS Dri-Shield® bags are designed to be
used with Desiccant and an HIC for packaging surface mount devices (SMD) trays and reels. The bags are sealed, including
being vacuum sealed, containing the SMD or other content along with the Desiccant and selected HIC. The HIC will note the
highest relative humidity exposure, so the user can determine if baking the devices is required. SCS recommends the user
follow procedures defined in IPC/JEDEC J-STD-033. SCS manufactures MBB and HIC products in Sanford, North Carolina.
®
SCS Desiccant pouches absorb moisture that passes through the bag laminate. Desiccant is packed inside Tyvek white
non-woven plastic or brown kraft paper pouches, and is shipped in sealed pails or drums. The amount of desiccant to use is
dependent on the interior surface area of the bag; see EIA-583, Table 1, SCS Desiccant is manufactured in North America.
