Rebaking Instructions
The LUMENOLOGY r Company
Optical characteristics of the device can be adversely affected during the soldering process by the release and
vaporization of moisture that has been previously absorbed into the package. To ensure the package contains
the smallest amount of absorbed moisture possible, each device is baked prior to being dry packed for shipping.
Devices are dry packed in a sealed aluminized envelope called a moisture-barrier bag with silica gel to protect
them from ambient moisture during shipping, handling, and storage before use.
The calculated shelf life of the device in an unopened moisture barrier bag is 12 months from the date code on
the bag when stored under the following conditions:
Rebaking of the devices will be required if the devices exceed the 12 month shelf life or the Humidity Indicator
Card shows that the devices were exposed to conditions beyond the allowable moisture region.
The CL package 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:
If the floor life or the temperature/humidity conditions have been exceeded, the devices must be rebaked prior
to solder reflow or dry packing.
When the shelf life or floor life limits have been exceeded, rebake at 50°C for 12 hours.
