Dry Box Storage Guideline by IPC/JEDEC
● IC Ｐａｃｋａｇｅ standard : IPC/JEDEC J-STD-033C
To comply with the IPC/JEDEC J-STD-033C, IC packages should be stored in a dry box that maintains a humidity level equal to or less than 5% RH or 10 % RH in order to keep them from adsorbing moisture after opening its moisture-proof packaging.
However, on the factory floor, the humidity level in the dry box may rise due to the frequency of opening the doors to load and unload devices. In order to prevent such a situation from occurring, and to consistently maintain the required humidity levels of less than 5% or 10% RH, ultra-low humidity dry cabinets set at 1%RH or 2%RH may be most recommended.
Storage in a cabinet below 5%RH: No limit in floor life.
