FR408 materials

High Performance Laminate and Prepreg

FR408 is a FR-4 epoxy laminate and prepreg system

FR408 has a low dielectric constant (known as Dk) and low dissipation factor (known as Df) which make it an ideal candidate for broadband circuit designs which require faster signal speeds or improved signal integrity.

The FR408 PCB features multilayer traces, with a dielectric layer between each layer, this dielectric layer itself consists of very thin layers.

This multilayered circuit board features three conductive layers. These electrical connection between them is usually done by plated through holes in the circuit board on the implementation of the cross section

FR408 Laminates

Isola’s FR408 is a high-performance FR-4 epoxy laminate and prepreg system designed for advanced circuitry applications. Thanks to it’s low dielectric constant and low dissipation factor it make it a great candidate for broadband circuit designs.

As a multilayer PCB, the FR408 is used in professional electronic equipment (ranging from computers to military equipment), especially in the case of weight and volume overload.

But this also applies to high speed circuits, where multi-substrate is also very useful, they can provide more than two layer boards for printed circuit board designers regarding laying cable, and provide a large area of soil and power.
