SC20-WL is stored in a vacuum-sealed bag. It is rated at MSL 3, and its storage restrictions are shown as
below.
1. Shelf life in the vacuum-sealed bag: 12 months at <40º C/90%RH.
2. After the vacuum-sealed bag is opened, devices that will be subjected to reflow soldering or other
high temperature processes must be:
 Mounted within 168 hours at the factory environment of ≤30ºC/60%RH.

Stored at <10%RH.
3. Devices require baking before mounting, if any circumstance below occurs.

When the ambient temperature is 23º C± 5º C and the humidity indication card shows the humidity
is >10% before opening the vacuum-sealed bag.
 Device mounting cannot be finished within 168 hours at factory conditions of ≤30ºC/60%.
4. If baking is required, devices may be baked for 8 hours at 120º C± 5º C.
