About High Tg PCB

High Tg PCB circuit board is basically defined as PCB raw material or designed to withstand high heat resistance in high temperature PCB, high Tg is usually higher than 170°C. Therefore, the PCB with TG greater than or equal to 170°C is high Tg PCB, which can also be called glass transition temperature. High heat resistance, commonly used in lead-free process.

FR4 TG is usually 130-140℃, and the middle TG is usually higher than 150-160℃. The humidity resistance, heat resistance, stability, chemical resistance and other properties of PCB during the manufacturing of high Tg PCB circuit board are directly dependent on the glass transition temperature.

We can help you determine if high temperature resistant printed circuit boards are needed and guide you to select the appropriate high Tg PCB circuit board. If your product is transitioning from lead-free to lead-free to RoHS instructions, or if you need to learn more about high Tg laminates, please contact us online or email to em01@huihepcb.com We will be happy to serve you.
