♦ What's High-Tg?

Tg refers to the glass transition temperature. When the substrate is exposed to high temperatures, it will change from a glass state to a rubber state. High Tg PCB refers to a circuit board that can withstand higher temperatures without deforming or turning into rubber. Materials with a glass transition temperature above 170°C are usually classified as high Tg PCBs, those above 150°C are mid-range Tg PCBs, and those above 130°C are low Tg PCBs.

♦ Features of High-Tg PCB?

• • Good heat resistance​​: The Tg value of ordinary PCB is generally 130-140°C, and the actual operating temperature may be lower than 100°C due to the influence of thermal expansion coefficient; while the Tg value of high Tg PCB exceeds 170°C, and the thermal expansion coefficient is between 5 ppm/°C and 8 ppm/°C, which can operate at higher temperatures and is less affected by heat.
  • High mechanical strength​​: It can withstand greater external forces and stresses, maintain structural stability in complex environments, and reduce the risk of damage.
  • Strong chemical stability​​: It has higher tolerance to chemical substances and can maintain stable performance in harsh chemical environments.
  • Good signal integrity​​: In high-frequency applications, it can provide better signal transmission and reduce signal loss and distortion.

♦ Application fields of High-Tg PCB

• • ​​Aerospace field: used in avionics, satellite communications, flight control systems, etc., adapting to harsh conditions such as extreme temperature and high radiation, and ensuring the high reliability of aerospace equipment.
  • ​​Medical equipment field: used in CT machines, MRIs, monitors and other equipment, withstanding high temperature and high pressure environments, ensuring the accuracy and safety of medical electronic equipment.
  • ​​New energy field: used in photovoltaic inverters, wind power converters, etc., withstanding high temperature and high current, improving energy conversion efficiency, and extending equipment life.
