Thank you everyone for the responses.
I will go and read the references referred to. This is the first time I
have
ever heard of Td or Halogene free.
Thanks Again

Lee,
How will the Td 5% weight loss effect the integrity of the laminate.

Joe,
Td for PCB is thermal decomposition temperature (generally >320°C). Is
anyone able to give a complete definition ? Merci,
Pascal

Accounts are moving to both high Tg and Td materials to accommodate the
higher assembly temperatures.
Best regards

I am curious if people have been automatically moving to higher Tg
laminates
to support lead free.
Any input would be appreciated
Thank You.
We are just starting down the lead free path and this forum has been a
great
help.
Thanks again
