Isola FR408 and FR408HR High-speed material Comparison Data

Choosing FR408 or FR408HR circuit material depends on various factors, such as characteristics and applications.

Here are the differences between them:

Ÿ FR408 is a high performance FR-4 epoxy laminate and prepreg system designed for advanced circuit applications that can accommodate multi-layer and advanced applications of circuit boards.

Ÿ FR408HR is a different type of PCB material based on FR-4. It is a high performance FR-4 resin system with a Tg of 230˚C (DMA) suitable for multi-layer PCB applications.

Ÿ FR408HR is well suited for multi-layer PCB applications, while FR408 is suitable for advanced circuit applications.

Ÿ FR408HR meets the needs of aerospace, networking and communications, defense, medical, industrial, and instrumentation, while FR408 meets these needs. The applications of FR408 are mainly based on applications that deal with improved signal integrity and wider bandwidth circuit design considerations.

How to choose the FR408 and FR408HR?

The choice between FR408 and FR408HR circuit materials depends on a variety of factors, such as properties and applications.

FR408’s core application areas are aerospace, computing, defense, medical, storage, and industrial applications; on the other hand, our core application areas include networking, peripherals, instrumentation, and communications equipment.

One of the big advantages of using FR408 is that it is a medium-loss PCB material. This means that it does not suffer from multiple losses or encounter certain limitations that can hinder the success of an immediate board design. It offers a combination of high performance and uses in innovative and complex boards.

 However, if you want to choose between FR408HR and FR408, you must base it on electrical and thermal performance—where the difference is small. The electrical properties of FR408 material are Dk: 3.67 and Df: 0.0120; the electrical properties of FR408HR material are Dk: 3.68 and Df: 0.0092.

On the other hand, we get the thermal performance of both as follows:

FR408HR: Tg: 190˚C and Td: 360˚C

FR408: Tg: 180˚C and Td: 360˚C
