Hi Bob,
Yes, there are documents and guidelines: IPC/JEDEC J-STD-033B & J-STD-020D,
and T. Sack & L. Scala of Celestica have published guidelines for bBaking
(typically at 125C), Bake-Drying (typically at 90C), and Drying (typically at 40C).
The durations vary according to the MSL Levels form 21 to 48 hours for
Baking, 3 to 8 days for Bake-Drying, and 29 to 79 days for Drying.
Werner
