FR408HR: Unveiling the High-Performance Laminate Material and Its Advantages

In the world of printed circuit boards (PCBs), selecting the right material is crucial for optimal performance, reliability, and durability. FR408HR is a high-performance laminate material that offers several advantages over its predecessor, FR408. In this article, we’ll explore the properties and benefits of FR408HR, how it compares to FR408, and the industries and applications where it thrives. We’ll also discuss how partnering with an experienced PCB manufacturer like MorePCB can ensure the success of your FR408HR projects.

What is FR408HR?

 Composition and Properties

FR408HR is a high-performance epoxy laminate and prepreg material with a unique blend of thermoset resin and a proprietary reinforced filler. Its composition results in outstanding performance characteristics:

  • Dielectric constant (Dk): 3.66 (at 1 GHz)
  • Dissipation factor (Df): 0.009 (at 1 GHz)
  • Thermal performance: Glass transition temperature (Tg) of 230°C

Compared to other laminate materials in the market, FR408HR offers superior electrical and thermal performance.

Advantages of FR408HR

  • Enhanced thermal performance: FR408HR is well-suited for high-power applications that demand better thermal management.
  • Improved signal integrity: Lower signal loss and higher signal speeds contribute to more efficient data transfer and overall system performance.
  • Higher reliability: FR408HR’s robust composition makes it more durable in harsh environments, ensuring a longer operational lifespan.

FR408 vs. FR408HR

Differences in Composition and Properties

While both FR408 and FR408HR belong to the same family of materials, there are key differences in their composition, which impacts their properties:

  • FR408HR contains a proprietary reinforced filler that enhances its thermal and electrical performance.
  • FR408HR has a higher glass transition temperature (Tg) and lower dissipation factor (Df) than FR408.

Selecting the Right Material for Your Application

Consider the following factors when choosing between FR408 and FR408HR:

    • Performance requirements: Assess your project’s thermal and electrical performance needs.
    • Budget constraints: FR408HR may come with a higher cost due to its advanced properties.
    • End-use environment: Consider the operating conditions your PCB will be exposed to, such as temperature extremes and humidity.

Applications of FR408HR Laminate Material

 Industries Using FR408HR

FR408HR is widely used in industries that require high-performance PCBs:

  • Aerospace: Satellite communications, radar systems, and avionics.
  • Telecommunications: High-speed data transfer and networking equipment.
  • Automotive: Advanced driver assistance systems (ADAS), electric vehicle (EV) power management, and infotainment systems.

Case Studies: Successful FR408HR Implementations

  • A telecommunications company used FR408HR to develop a high-speed networking device, resulting in improved signal integrity and reduced signal loss.
  • An aerospace manufacturer implemented FR408HR in a satellite communication system, enhancing thermal management and extending the operational life of the system.
