Multilayer High Temperature Resistant Environmentally Friendly High Tg PCB

♦ 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

• • Communication field: widely used in wireless base stations, optical fiber communications, satellite communications and other equipment, supporting high-speed signal transmission, adapting to high temperature and high frequency environments, and ensuring stable operation of communication networks.
  • Automotive field: used in vehicle computers, engine control units, new energy battery management systems, etc., to withstand high temperatures, vibrations and complex environments, and improve the reliability of automotive electronic systems.
  • Industrial field: suitable for industrial automation equipment, PLCs, converters, etc., can work stably in high temperature, high humidity, and strong vibration environments, ensuring long-term and reliable operation of industrial equipment.
