Attached is the JSTD-033 standard, actually it does not have any specifics
but the looks like <30deg is the requirement. Our customer's recommendation
is control between 40 to 60%RH, 23 +/-5deg.

 

Thanks and Best Regards,

Subject: [TGA] Storage requirement for moisture sensitive components

 

All,

 

Does anybody know what the requirements for moisture sensitive component
storage are? Does IPC/JEDEC J-STD-033 explain how the storage environment
should be? How about controlling the temp from 18C-30C and humidity from
30%-70% RH? Are they adequate? If we cannot make sure the humidity is lower
than 70% all the time, will applying vacuum packaging solve the issue as you
know the humidity will affect solderability and insulation resistance. Any
comment will be appreciated. Thanks.
