Notes

16. To achieve the thermal impedance specified for the QFN package, the center thermal pad must be soldered to the PCB ground plane.

17. Higher temperatures may be required based on the solder melting point. Typical temperatures for solder are 220 ± 5°C with Sn-Pb or 245 ± 5°C with Sn-Ag-Cu paste.

Refer to the solder manufacturer specifications. For a recommended soldering profile, refer to Application Note 49035, Manufacturing Considerations for the Ovation-
