LMG3522R050: two-time reflow process

Part Number: LMG3522R050


Can the LMG3522R050 component be reflow soldered on the underside of the PCB? In other words, it would undergo the reflow process twice. Can the component withstand this?

Thank you,

  • Hi Sterie,

    Thanks for reaching out.

    Page 14 of this application note gives the reflow profile of the our QFN devices.

    Please read all of section 5.2 of the document as there are several key points that should be followed. The profiles shown are just examples.

    Note: “TI recommends use of the temperature profile from the solder-paste manufacturer to optimize flux activity within the MSL guidelines for the most thermally sensitive component. See J-STD-033 for more details on MSL classification.”

    Hope this helps.

    Best,

    Pratik A.
