Pascal,
Where in the IPC Standard can I find literature on Tg and Td for FR4
Class 3 for SnPb and LF temperatures.

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
John Foster
