Hello,

Could you give me guideline on how to set-up PWI limits for SMT ?

I experienced a +10oC drift in max-temperature on a transformer between a profile taken a year ago and recently.   I am concerned about the potential impact it has on the component (over-temperature).
My CM currently operates at 230-260C peak-temp range  which seems broad;   how does this compares to industry best-practices ?

Thanks for the help.

Fabien
