LM317: Reflow profile

$

Part Number:LM317

Hello,

My customer intend to choose LM317DCY for their 2020 product.

~~~~~~~~~~~

Question


We see MSL rating/peak reflow from TI web site as Level-2-260C-1 YEAR, but can not found reflow profile.

May I understand LM317DCY reflow profile is  snoa550e.pdf Fig 1 ?


www.ti.com/.../snoa550e.pdf

~~~~~~~~~~

Where:


*LM317DCY size: 6.6mmx 3.5mm x 1.8mm(thickness)

*LM317DCY volume:22.75 mm^2


*We see following from app note from Page 4 Table2,

thickness 1.6-2.5mm/ volume <350mm ==> Max peak body temperature 260deg-C

So, I can see reflow profile of LM317DCY from Pag4 5 Fig1 & Table 4

as Pb-free Assembly case( Tp=260deg-C , TL=217 deg-C)


Is this correct?

Thank you for your support

Best Regards
