Are there product or package exceptions to the standard Pb-Free or Eutectic qualification reflow profiles? How do you determine which products these are and what is the different profile to use for each?

Yes, there are exceptions due to the materials used in certain package types. These products have special suffixes added to the normal product part number as listed below with their profiles.

Product Part Numbers with G36 suffixes have a peak temperature of 225 (-5/+0) degrees Celsius.
