detailed in J-STD-033 Rev. A (Handling, Packing, Shipping and
Use of Moisture/Reflow Sensitive Surface Mount Devices).
Moisture barrier bags (MBB) with desiccant are required for MSL
ratings of 2 or greater. These sealed packages should not be
broken until time of use. Once the original package is broken,
the floor life of the product at conditions of 30°C and 60%
relative humidity varies according to the MSL rating (see J-STD-
025A). The shelf life for dry packed SMT packages will be a
minimum of 12 months from the bag seal date, when stored at
the following conditions: < 40° C, < 90% relative humidity.
Post Solder Cleaning and Drying
Considerations
Post solder cleaning is usually the final circuit-board assembly
process prior to electrical board testing. The result of
inadequate cleaning and drying can affect both the reliability of
a power module and the testability of the finished circuit-board
assembly. For guidance on appropriate soldering, cleaning and
drying procedures, refer to GE Board Mounted Power Modules:
Soldering and Cleaning Application Note (AP01-056EPS).
EMC Considerations
The circuit and plots in Figure 24 shows a suggested
configuration to meet the conducted emission limits of EN55022 Class B. For further information on designing for EMC
compliance, please refer to the FLT007A0 data sheet.
