Recommendations for IC Package Storage after Opening Moisture-Barrier Bags
As specified by IPC/JEDEC Standard 033D
|Storage Method||Workability and Cost||Result|
|1||Use before floor life ends||
|2||Storage in dry box||
||Optimal storage and easy operation|
Level and Floor Life of IC packages
IPC/JEDEC J-STD-033D (Joint Electron Device Engineering Council)
The floor life of IC packages after removal from moisture-barrier bags is classified into the levels shown below.
|Level||Floor life (Moisture absorption life when IC packages are left in factory conditions at < 30℃ and < 60%RH after removal from moisture-barrier bags)|
|1||No specific floor life in factory conditions < 30℃ and < 85%RH|
|6||Baking is required.|
Label on Moisture-Barrier Bags
It is compulsory to indicate the level, floor life and storage temperature after unpacking on the moisture-barrier bags.
