What is High TG PCB

High-TG PCB refers to printed circuit boards built from high-temperature Fr4 material. PCB materials must have flame resistance. It can only be softened by heat and cannot burned. The critical temperature called the term “glass transition temperature” (Tg).

HIGH TG PCB

 

What is Standard Tg?

 
As usual made with Tg ≥ 170 ℃ PCB material that as a High Tg circuit board. With the rapid development of the electronics industry. high Tg material is widely used in computers. communication devices, precise apparatus, and instruments, etc.
 

What is Tg in FR4?

 
FR4 is a code name for the level of epoxy glass material. Tg means glass transition Ordinary PCB materials are not only softened, deformed. melted and other phenomena at high temperatures. but also the mechanical and electrical properties decrease significantly.
 
 

type

When the working temperature reaches the melting point. which means that the temperature exceeds the Tg value. the status of the PCB material changes from a glassy to liquid, which affects the function of PCB. And this value care about the stability of the PCB dimensions.
