Polyclad and Isola websites have all the information you need (even if you
are buying other materials, shhhh)

As for specific temperature ratings, you need to make sure the Tg is suited
for the end use, for example, you might not want to use a material with Tg
of 130 in a hot, humid, hostile type environment, not matter what the cost
savings are...

Subject: [TN] Laminate Rating


Fellow TechNetters;

   Where can I get information on Laminate rating such as FR1 versus FR4
application with regards to Tg.
Can these laminate be interchange due to cost?   What are the Pros and
Cons with this issue.

  In advance I thank you for sharing your experience with me.

Victor,
