is it ok for mesa card to not use it for a long time?

Hello,

I have just quick question.
Is it ok for mesa card (I have 7i92 and 7i96S) to not be used for some time?
I got them half a year and think next half a year I will not use them so they wont be used for a year.

Idk if can something happen to fpga chip for example..

thx

I see no problem when packed well...
ESD protected, moisture proof, etc.

I had some sitting in a suitcase for over 3 years, they work as now they are all installed, all i got left to play with are 6i25 and 7i73, and when i yank out of the machines one of several 7i92.
