High TG PCB


What is TG?

Most PCBs are constructed with material that has a TG value of 135C. This can withstand operating temperatures of up to 110℃ TG stands for glass transition temperature and indicates the temperature at which the printed circuit boards' (PCB) material starts to transform. If the operating temperature exceeds the designed TG value of the PCB base material, the board will change from a solid to a liquid state and this will affect its function and performance.high TG PCB


What is High TG PCB Board?

Normally high Tg refers to high heat resistance in PCB raw material, the standard is between 130 – 140C, High Tg is generally greater than 170C, popular TG is 170C, 175C and 180C.We offer High-TG PCBs that have a TG value of up to TG 280.


High-TG PCB Application

High-TG PCB are suitable for applications that generally involve extreme temperature variations, such as automobile electronics, industry electronics, and high-temperature electronics.


High-TG Parameters

The parameters of the materials available in our High-TG PCBs are as follows:

MaterialTG(DSC,°C)
King Board175
Sheng Yi175
Rogers280

In addition to above brands, for normal FR4 material you can also classify high TG materials as below datasheet.

FR4-standard-TG130°C110°C
FR4-mittel-TG150°C130°C
FR4-hoch-TG170°C150°C
Polyimid-Super-hoch-TG-Material260°C240°C

The MOT(Maximum Operating Temperature) means the highest temperature under which the PCB can permanently operate without being damaged. 

Advantages of High-TG materials

* High-TG materials have higher MOT, it also allows higher currents.For example, 130TG board, working temperature will be lower than 110C; if use 170 high TG board, maximum working temperature should be lower than 150C.
* High TG Circuit Board has better heat resistance, moisture resistance, chemical resistance and stability.
* High TG PCB will perform better than general FR4 in mechanical strength, dimensional stability, adhesiveness, water absorption and thermal decomposition.
