What is FR-408

FR-408 is a high-performance laminate and prepreg material. Developed by Isola, FR-408 is specifically designed for advanced circuitry applications that require exceptional thermal and electrical performance.

One of the key features of FR-408 is its low dielectric constant (Dk) and dissipation factor (Df), which contribute to its advantages in signal transmission and integrity. The low Dk and Df values ensure efficient energy storage and dissipation, resulting in reliable and accurate signal transmission.

FR-408 is known for its compatibility with FR-4 processes, a common epoxy material used in PCB fabrication. This compatibility allows for easy integration into existing manufacturing processes without the need for complex modifications.

Additionally, FR-408 offers excellent thermal performance, with a high glass transition temperature (Tg) of 230°C. This high Tg value ensures that the material remains stable even at elevated temperatures, making it suitable for applications that require reliable operation in demanding environments.

Furthermore, FR-408 has received industry recognition and complies with RoHS regulations, ensuring its adherence to quality and environmental standards.
