High-TG PCB:

The Glass Transition Temperature (Tg) is one of the most important properties of any epoxy and is the temperature region where the polymer transitions from hard, glassy material to a soft, rubbery material.

Circuit board material must flame-resistant, it can’t be burned at a certain temperature and only be softened. The temperature point is called the glass transition temperature (Tg).

The higher Tg point means a higher temperature requirement during lamination. And the boards will be hard and crisp, which will affect the hole and the electrical properties.

Ordinary PCB materials at high temperatures, not only will be softened, deformation, melting and other phenomena, but also the mechanical and electrical properties decline sharply.

General FR4 Tg is 130-140 centigrade, moderate Tg is greater than 150-160 centigrade, High-Tg is greater than 170 degrees.

The higher of Tg, the better the performance of PCB heat resistance, moisture resistance, chemical resistance, stability and other characteristics.

FR4 is a code name for the grade of Epoxy Glass material.
