MBBs contain one or more desiccant pouches to absorb moisture that may be in the bag. The
humidity indicator card described below should be used to determine whether the enclosed
components have absorbed an excessive amount of moisture.
The desiccant pouches should not be baked or reused once removed from the MBB.
The humidity indicator card is a moisture indicator and is included in the MBB to show the ap-
proximate relative humidity level within the bag. Sample humidity cards are shown in Figure 51.
If the components have been exposed to moisture above the recommended limits, the units will
have to be rebaked.

A baking is required if the humidity indicator inside the bag indicates 10% RH or more.
4.3.2.2 Transportation Box
Tape and reel carriers are distributed in a box, marked with a barcode label for identification
purposes. A box contains two reels with 500 modules each.
