TMD3725 − Soldering & Storage Information

Shelf Life

The calculated shelf life of the device in an unopened moisture

barrier bag is 24 months from the date code on the bag when

stored under the following conditions:

• Shelf Life: 24 months

• Ambient Temperature: <40°C

• Relative Humidity: <90%

Rebaking of the devices will be required if the devices exceed

the 24 months shelf life or the Humidity Indicator Card shows

that the devices were exposed to conditions beyond the

allowable moisture region.

Floor Life

The module has been assigned a moisture sensitivity level of

MSL 3. As a result, the floor life of devices removed from the

moisture barrier bag is 168 hours from the time the bag was

opened, provided that the devices are stored under the

following conditions:

• Floor Life: 168 hours

• Ambient Temperature: <30°C

• Relative Humidity: <60%

If the floor life or the temperature/humidity conditions have

been exceeded, the devices must be rebaked prior to solder

reflow or dry packing.

Rebaking Instructions

When the shelf life or floor life limits have been exceeded,

rebake at 50°C for 12 hours.
