Surface Mount Information (continued)
Pb-free Reflow Profile
Power Systems will comply with J-STD-020 Rev. C
(Moisture/Reflow Sensitivity Classification for Nonhermetic
Solid State Surface Mount Devices) for both Pb-free solder
profiles and MSL classification procedures. This standard
provides a recommended forced-air-convection reflow profile
based on the volume and thickness of the package (table 4-2).
The suggested Pb-free solder paste is Sn/Ag/Cu (SAC). The
recommended linear reflow profile using Sn/Ag/Cu solder is
shown in Figure 22.
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:
