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 Lineage Power Board
Mounted Power Modules: Soldering and Cleaning

Through-Hole Lead-Free Soldering
Information
The RoHS-compliant through-hole products use the
SAC (Sn/Ag/Cu) Pb-free solder and RoHS-compliant
components. They are designed to be processed
through single or dual wave soldering machines. The
pins have an RoHS-compliant finish that is compatible
with both Pb and Pb-free wave soldering processes. A
maximum preheat rate of 3
°C/s is suggested. The
wave preheat process should be such that the
temperature of the power module board is kept below
210
°C. For Pb solder, the recommended pot
temperature is 260
°C, while the Pb-free solder pot is
270
°C max. Not all RoHS-compliant through-hole
products can be processed with paste-through-hole Pb
or Pb-free reflow process. If additional information is
needed, please consult with your Lineage Power
representative for more details.
