Morning all,

I have a question regarding HIC cards. We have one style here in our stock
room that we have new in a can. Last Thursday when it was 77% relative
humidity, you could take one of the HIC cards out of the can (it was the
lower right hand card in the photo) and literally watch the 5% & 10% dots
turn pink within 20-minutes. So according to the card, if a sealed MBB that
contained MSL3 parts was opened, and 20-minutes later both dots turned pink
I would have to bake the parts, correct? The problem with that is that the
bag was only opened for 20-minutes, not 168-hours. I'm just asking the
question the same way a stockroom clerk would ask it. What are they
supposed to do when they see a  pink card?

BTW, all three cards have been sitting out all weekend and came in with
bare PCB's and other parts that we received in. I know the humidity has
been at least 77% over the weekend, and it's 57% this morning. All the dots
on all the cards should be pink, correct? How much faith do you put in the
HIC cards when you see this kind of variability?
