TPS54620: TPS54620 best practice storage and remove/replace tools

Hi David,

The baking procedure varies and is dependent on thickness and moisture levels. For more details on the process, please refer to our app note: https://www.ti.com/lit/an/snoa550h/snoa550h.pdf. We also have a Moisture sensitivity tool that can be found here: Moisture Sensitivity Level Search Tool.

For reference, TPS54620 has a thickness of 1mm so according to table 5 in the App note, it's doesn't require baking if Floor Life exposure is limited to < 30C and < 60%RH for thin (< 1.4 mm) MSL2 devices. This is due to the moisture diffusion behavior of the thin devices, which were fully saturated after the absorption at MSL 2 (168 hours @85C/60%RH).

Regards,

Eileen
