Hello TechNetters,

Why does FR4 material is so common in PCB manufacturing
and the demand is great?
Why not poliyimide? Teflon? etc.

What are FR4 advantages over those mentioned above?

Was it Tg?

By the way FR4 Tg is 145?
If this is so if we subject the material in 320 Deg C, Is this material
degrades?
Any expalanation for this is highly appreciated

Thanks
