Product Description


Humidity Indicator Cards for the Printed Circuit Board Industry 



What are humidity indicator cards ?


Humidity Indicator Cards (HICs) are vital tools in the PCB industry, designed to monitor and display the relative humidity (RH) levels within packaging environments. These cards change color to visually indicate the current humidity level, helping to ensure that sensitive electronic components are protected from moisture


How Does Humidity Affect Printed Circuit Boards( PCBs) ?

Excess humidity can wreak havoc on PCBs, causing issues like corrosion, soldering defects, and reduced insulation resistance. This can lead to product failure and decreased reliability. Managing humidity levels is crucial to maintain the integrity and performance of PCBs.


Industry Packaging Standards for PCBs

The industry standards for PCB packaging typically include the use of moisture barrier bags, desiccants, and humidity indicator cards. This combination ensures a dry environment during shipping and storage, adhering to the IPC/JEDEC J-STD-033 standards for moisture-sensitive devices.
