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. The suggested Pb-free solder paste is Sn/Ag/Cu (SAC). The recommended linear reflow profile using
Sn/Ag/Cu solder is shown below.
MSL Rating
The SLIN-30E1Ax modules have a MSL rating of 2.
Storage and Handling
The recommended storage environment and handling procedures 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 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-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.
