Humidity Indicator Cards

Confirm that your moisture barrier bags and desiccants have done their job by adding a Humidity Indicator Card (HIC) to each package. Moisture sensitive spots on the HIC respond to various levels of humidity with a visible color change from blue to pink. Examining the card when you open the bag will indicate the humidity level components are experiencing, and will help to determine whether the components are dry enough for solder reflow.
