Humidity Indicator Crds in sealed packages of PCBs. | 11 August, 2022

I have a question about Humidity Indicator Cards (HIC) in sealed PCB packages. If a PCB package is temporarily opened where the HIC card indicates 20% humidity exposure and then the PCB package is resealed with a new HIC card. How is the 20% moisture exposure on the "old" HIC card accounted for since the "new" HIC card indicates 0% exposure?

Humidity card should show actual humidity in the package accurately. If it shows below 10%, actual humidity should be less than 10%. There is nothing to account for from previous cards.

The humidity card must reflect the precise level of humidity present in the shipping container. If the reading is less than 10%, then the relative humidity is less than 10%.
