G11 Sheet vs FR4 Sheet: Which Is Better for High-Temperature Electronic Boards?

When it comes to high-temperature electronic boards, choosing the right material is crucial for ensuring optimal performance and longevity. G11 sheet and FR4 sheet are two popular options, but which one is better? For high-temperature applications, G11 sheet is generally the superior choice. G11 offers enhanced thermal stability, higher glass transition temperature, and better electrical properties at elevated temperatures compared to FR4. While FR4 is suitable for many standard applications, G11's ability to maintain its mechanical and electrical characteristics at temperatures exceeding 150°C makes it the preferred option for electronic boards operating in high-temperature environments. However, the final decision should consider specific project requirements, cost constraints, and performance needs.
