Werner,
Is not the glass transition temperature (Tg) more important than Td? I
would not want to approach the Tg, or at least not for more than 2-3
seconds. In my mind, if I reach the Td it is already too late,
reliability is compromised. I am assuming the Td is a higher internal
temperature than the Tg.

Hi sona,
Do determine that, you need the decomposition temperature, Td.
