1. Automotive electronics

Automotive electronic systems (e.g., engine control units, sensors and in-car entertainment systems) often operate in high-temperature environments, especially in engine compartments or under high summer temperatures. High Tg PCBs are able to maintain stable performance at high temperatures to ensure the reliable operation of automotive electronics.

2. Aerospace

Aerospace equipment is often required to operate in extreme temperature conditions, from the extremely low temperatures of space to the high temperatures of engine compartments, and high Tg PCBs provide stable performance to meet the demanding requirements of the aerospace industry.

3. Industrial Control

Industrial automation equipment and high-performance computing devices usually need to operate in high-temperature environments for long periods of time, high Tg PCBs can effectively deal with the challenges of high temperature and mechanical stress to ensure the long-term stability of the equipment.

4. Communication equipment

5G communication equipment and base stations need to maintain high performance in high-temperature environments. The low loss and high reliability of high-Tg PCBs make them the preferred material for communication PCBs.

5. Outdoor electronic equipment

Outdoor electronic equipment (such as solar power systems, weather monitoring stations and outdoor lighting equipment) need to cope with extreme conditions of high temperature, high humidity and low temperature, high Tg PCB can provide reliable performance guarantee.

High Tg PCB vs FR-4 PCB

As can be seen from the table, high Tg PCBs outperform FR-4 PCBs across the board in high temperature environments, and despite their slightly higher cost, their reliability and stability in extreme environments make them a better choice.。

Summaries

In extreme environments, electronic devices need to face multiple challenges such as high temperature, high humidity, low temperature, vibration and chemical corrosion, etc. The performance of traditional FR-4 PCBs in high temperature and complex environments is often difficult to meet the demand. High Tg PCBs have become the material of choice for extreme environments due to their excellent thermal stability, low coefficient of thermal expansion, high mechanical strength, and excellent high-frequency and high-speed performance.

With the increasingly complex working environment of electronic equipment, the importance of high Tg PCB will be further highlighted. In the future, high Tg PCB will play a greater role in the field of automotive electronics, aerospace, industrial control, communication equipment, etc., to provide more reliable support for electronic equipment in extreme environments, and help the continuous development of modern technology.
