Halogen-free compositions meeting environmental regulations
High CTI versions for operation in harsh conditions
The continued preference for FR-4 PCBs across industries stems from their unmatched combination of performance, reliability and cost-effectiveness. As material science and manufacturing technologies advance, FR-4 remains the substrate of choice for everything from prototype development to high-volume production, delivering consistent quality and dependable performance in even the most demanding electronic applications.
As the most widely used PCB substrate in the electronics industry, FR-4 glass-reinforced epoxy laminates provide the perfect combination of electrical performance, mechanical durability, and thermal stability. These high-performance circuit boards serve as critical components in applications ranging from consumer electronics and telecommunications equipment to automotive systems and aerospace technology.
With a dielectric constant between 4.3-4.8 at 1MHz and dissipation factors below 0.02, FR-4 PCBs maintain excellent signal integrity even in demanding high-frequency applications. The material’s superior insulation resistance (exceeding 10⁸ megohms) and high breakdown voltage make it ideal for circuits requiring reliable isolation between conductive layers.
