Normally fr4 tg150 is 130-140°, moderate Tg is over 150-160 °, High-Tg is greater than 170°.The higher of Tg, the better performance of PCB moisture resistance, heat resistance, chemical resistance, stability and other characteristics.

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

Normal tg150 fr4 ranges from 130 to 140 degrees, moderate Tg is higher than 150 to 160 degrees, and China high tg pcb 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 China high tg150 pcb. Greenstone is a China high tg pcb supplier which can provide satisfied high tg pcb. These days, computers, precision instruments, communication devices, etc., all frequently use high Tg materials.

Uses and Applications of High-tg PCB

As usual, made with Tg ≥ 170℃ PCB material, which is called a high Tg printed circuit board. With the rapid development of the electronics industry, china high TG PCB material is widely used in

computers

communication equipment

precise apparatus

Instruments

Power supply devices
