How to distinguish high Tg materials?
The definition of Tg is “glass transition temperature”. Many ceramic substrates, polytetrafluorovinyl materials, and polyimide (PI) substrates do not contain any glass fibers, so there is no Tg value. But for these three substrates, it can generally be considered that their Tg is greater than 200°C. In this case, Tg only represents high temperature resistance.
