Lead Free Low CTE High Tg PCB Suitable for A Variety Of Extreme Environments

♦ 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.

♦ Advantages of High Tg PCB

• • Improve product reliability: Stable physical and electrical performance in extreme environments, suitable for fields with high reliability requirements such as aerospace, automotive electronics, etc.
  • ​​Extend service life: Resistant to moisture and chemical corrosion, reduce maintenance costs, and bring economic benefits.
  • ​​Adapt to lead-free process: Can remain stable at higher welding temperatures, which is conducive to improving production efficiency and product quality.
  • ​​Support high-density interconnection technology: Meet the needs of miniaturization and lightweight of modern electronic equipment, making PCB design more refined and layout more compact.

♦ 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.
