Surface Mount Information
MSL Rating
The QW series SMT modules have a MSL rating of 2.
Storage and Handling
The recommended storage environment and handling proce-
dures for moisture-sensitive surface mount packages is
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 pack-
ages should not be broken until time of use. Once the origi-
nal 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-033A). 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 Tyco
Electronics Board Mounted Power Modules: Soldering and
Cleaning Application Note (AP01-056EPS).

Solder Ball and Cleanliness Requirements
The open frame (no case or potting) power module will meet
the solder ball requirements per J-STD-001B. These require-
ments state that solder balls must neither be loose nor violate
the power module minimum electrical spacing.
The cleanliness designator of the open frame power module
is C00 (per J specification).
