Glass Transition Temperature is referred to as Tg, and FR4 is a designation for a particular type of epoxy glass.

Normal FR4 Tg ranges from 130 to 140 degrees, moderate Tg is higher than 150 to 160 degrees, and pcb high Tg is more than 170 degrees.

The performance of PCB anti-moisture heat resistance, chemical resistance, quality stability, and other properties improves as Tg increases.

Tg 170°C PCB material is referred to as a high Tg PCB. Greenstone is a China high tg pcb assembly company which can provide satisfied high pcb tg. These days, computers, precision instruments, communication devices, etc., all frequently use high Tg materials.

Uses and Applications of China High TG PCB
