TN-00-01: Moisture Absorption
Device Baking
Device Baking
If the seal on the shipping container has been broken or if the devices have been
removed from their shipping containers and exposed to high levels of moisture, Micron
recommends a device bake-out procedure before surface mounting.
Devices not stored in sealed moisture barrier bags require baking before mounting if any
one of the following statements is true:
1. Devices have been stored at >20% RH.
2. The humidity indicator card is >20% RH when read at 23°C (+5°C).
3. The product floor life has expired (specified on the packaging label).
Table 2 outlines the bake-out requirements specified in IPC/JEDEC standard J-STD-033
(see the latest revision) and recommended by Micron. These are listed by package thick-
ness and moisture sensitivity level. Devices may be baked at 125°C for high-temperature
device containers. Additional bake-out conditions are provided in Table 2 for cases
where the device containers cannot be subjected to high temperature, or shorter bake
times are desired.
In the cases of mNAND and SSD products, baking is not allowed on units already
programmed at customer side. In the cases where a bake is needed on units already
programmed, the units must be reprogrammed after baking.
