In recent years, there has been an increasing demand for SysPCB to manufacture high Tg PCBs. In the following, we will describe what high Tg PCBs are and their significance.


What is Tg?


Tg stands for Glass Transition Temperature. The standard Tg for copper-clad laminates typically ranges between 130 – 140℃. High Tg is generally considered to be greater than 170℃, while middle Tg falls between 150℃ to 170℃.


High Tg PCBs


A printed circuit board with Tg ≥ 170℃ is referred to as a high Tg PCB. SysPCB also specializes in manufacturing PCBs with Tg ≥ 180℃. For applications requiring even higher temperature resistance, Teflon PCB (PTFE) can operate at temperatures up to 260℃, with the highest temperature reaching 290-300℃. Increasing the Tg of the PCB substrate enhances its heat resistance, moisture resistance, chemical resistance, and overall stability. High Tg PCBs are commonly used in lead-free PCB manufacturing processes.


Manufacturing Challenges


High Tg PCBs present manufacturing challenges due to the fragility of the base material. This can lead to difficulties during processes such as line etching, drilling, and routing. PCB suppliers typically require specialized equipment and tools to ensure high-quality PCBs with high Tg.


By manufacturing PCBs with higher Tg, SysPCB ensures improved performance and reliability, particularly in applications demanding high-temperature resistance and durability.
