High Tg PCB


High Tg PCB

For FR-4 high Tg PCB, CTT has the experience and quality you expect. If the boards you are using now are subject to high temperatures, you may need to use high Tg PCBs to ensure that these PCBs can withstand high temperatures without distortion.

If you are not sure if you need Tg PCB or are not familiar with high Tg PCB, we will be happy to help you solve all your concerns. Read on to the following questions about high Tg PCBs to get a complete picture of how high-temperature PCBs work and what it can do for you.

Generally, the Tg PCB is 130 degrees or more, the high Tg PCB is generally more than 170 degrees, and the medium Tg is greater than about 150 degrees.

When the Tg of the baseboard is improved, the heat resistance, moisture resistance, chemical resistance, and stability resistance of the circuit board get improved at the same time. The higher the Tg value, the better the temperature resistance of the board, especially in the lead-free process, the high Tg application is more.


High Tg PCB refers to high heat resistance. With the rapid development of the electronics industry, especially the electronic products represented by computers, the development of high functionality and high multi-layer requires the higher heat resistance of PCB substrate materials as an important guarantee.

Therefore, the difference between general FR-4 and high Tg FR-4 is that in the hot state, especially under heat absorption after moisture absorption, the mechanical strength, dimensional stability, adhesion, water absorption, thermal decomposition, there are differences in various conditions such as thermal expansion, and high Tg products are significantly better than ordinary PCB substrate materials. In recent years, the high Tg PCB demanding has increased.
