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 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 Tg 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

—— Mark from a leading LED strips supplier in Australia Match,8th 2018.

The goods arrived very well, the packing is good, thank you.

—— Antonio from Valladolid, Spain May 25th, 2017.

We've been worked with GreensTone for many years, there is no failure.

—— Wally Nunn from Australia---a leading Pool products manufacturer July13th, 2016.

I reached out to GreensTone Electronics to manufacture the circuit boards. After a few discussions, Rebecca could see the community focus of the project and went above and beyond to reduce costs, ensure delivery and filmed elements of the production for educational purposes. Manufacturing offshore isn't as easy as it appears on the surface so it was invaluable to have Rebecca believe in the cause and be an ally in the production working toward the same goal.

—— Mic. from Australia Feb. 10th, 2015, written on his Facebook.

Yes, thank you we received the 34x LC VMS TILE 1C REV A earlier this week. The assembly quality is very good.

—— Ruth from Australia April 9th, 2014.

Thank you for taking time to check it,you are very efficient.

—— Peter Astrom from Sweden Sep 8th, 2013.
