GESP TECH -TRUSTWORTHY ONE-STOP PCB SERVICES HIGH TG PCB
Introduction
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). Allow GESP PCB experts to advise you on how a high Tg board functions. and what it can do for you if you are unsure whether your operation calls for one. We have the technical know-how to satisfy your requirement regardless of its size or complexity.

ADVANTAGES OF HIGH TG PCB
Higher Stability:
If you raise the Tg of a PCB substrate, it will automatically improve the device’s resistance to heat, chemicals, and water, as well as its stability.
Be careful with designs that have a lot of power:
A high Tg PCB is a good way to deal with heat if the device has a lot of power and makes a lot of heat.It is possible to change the design and power needs of a device by using a larger printed circuit board and reducing the heat that an ordinary board makes. It is also possible to use a high Tg PCB.
Ideal for multilayer and high-density interconnect (HDI) PCBs:
There will be a lot of heat dissipation because multilayer and HDI PCBs are smaller and have more circuits. So, multilayer and HDI PCBs often use high Tg PCBs to make sure reliability in PCB fabrication.

FAQs OF 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.
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.
APPLICATIONS OF HIGH TG PCB

Commercial Applications
The majority of industrial applications necessitate harsh chemical, electrical, and temperature conditions. This is why these PCBs are widely used in industrial applications such as drilling machines, high-power presses, power inverters, and solar power equipment.

Automobile Industry
Automobile appliances contain PCBs with a high Tg. The produc tion of automatic and autonomous vehicles has increased the demand for these PCBs. High Tg PCBs are utilized in radar technology, control systems, and navigation devices in the automotive industry.

Computer Technology
In a similar fashion, these PCBs are utilized in computer technology, telecommunication appliances, security systems such as fire alarms, Wi-Fi boosters, high-processing antennas, gateways, embedded computer systems, and other medical and aeronautical appliances where high heat is present.
