Halogen-free PCBs

Halogen-free PCBs are circuit boards made without bromine and chlorine-containing flame retardants. These materials are commonly used in standard FR-4 PCBs but can be harmful to the environment and health. Halogen-free PCBs offer an environmentally friendly alternative with improved electrical properties, higher temperature resistance, and lower toxicity.

Advantages of Halogen-free PCBs

With their environmentally friendly and high-performance properties, halogen-free PCBs are a preferred choice for numerous applications. They are RoHS-compliant and contain no harmful halogens like bromine or chlorine, making them particularly eco-friendly. Their improved electrical properties, such as a lower dielectric constant (Dk), ensure optimal signal quality. They also offer high thermal stability and can withstand temperatures up to 30000b0C. Another benefit is their low smoke and toxic gas emission, providing increased safety for critical applications. Because of these features, they are ideal for high-speed and high-frequency circuits.

Types of Halogen-free PCB Materials

Depending on application requirements, various halogen-free PCB substrates are available:

  • Halogen-free FR-4 offers improved thermal stability and is a widely used standard solution.
  • High-Tg Halogen-free (Tg >17000b0C) is ideally suited for high-performance and high-temperature applications.
  • Halogen-free Polyimide PCBs are the best choice for flexible and rigid-flex designs.
  • Isola & Rogers Halogen-free offer optimal high-frequency performance, especially for 5G and telecommunication applications.

Typical Areas of Application

Halogen-free PCBs are used in sectors with high environmental and safety requirements. In medical technology, they ensure safe materials in portable and stationary medical devices. The automotive industry and electromobility benefit from reduced emissions, making them ideal for eco-friendly vehicles. In telecommunications and networking, they ensure optimal signal quality at high frequencies. They are also used in industrial electronics, offering sustainable solutions for controls and sensors. Furthermore, they are used in consumer electronics, such as smartphones, tablets, and smart home technologies.
