Manufacturing Process Recommendations
Figure 4: SKW72 Typical Leadfree Soldering Profile
Note：The final soldering temperature chosen at the factory depends on additional
external factors like choice of soldering paste，size，thickness and properties of the
baseboard，etc. Exceeding the maximum soldering temperature in the recommended
soldering profile may permanently damage the module.
FCC Statement
