Humidity Indicator Cards (HIC)
SCS Humidity Indicator Cards (HIC) provide a simple, reliable way to monitor moisture exposure in sealed packaging. Each card is printed with moisture-sensitive spots that change color from blue to pink when exposed to specific relative humidity (RH) levels, allowing users to quickly assess whether moisture-sensitive devices may require baking.
Key Features:
- Accurate Moisture Monitoring: Clearly indicates the highest humidity level inside sealed packaging.
- Color-Changing Spots: Moisture-sensitive spots transition from blue to pink as humidity increases.
- Ideal for Use with Moisture Barrier Bags: Designed to be used inside Moisture Barrier Bags along with Desiccant to protect sensitive electronics.
- Supports Industry Standards: Recommended for use per IPC/JEDEC J-STD-033 for handling moisture-sensitive devices.
- Manufactured in North America: SCS produces HICs in Sanford, North Carolina for quality and consistency.
How Humidity Indicator Cards Work

Humidity Indicator Cards are placed inside sealed Moisture Barrier Bags containing moisture-sensitive devices, such as surface mount device (SMD) trays and reels. When used with Desiccant, these cards allow users to monitor humidity levels and determine if baking is necessary before use.
