As the demand for high-performance printed circuit boards (PCBs) continues to rise, our newly shipped double-sided PCB, constructed from Rogers RO4003C material, stands out as an exemplary solution for a broad range of applications. Let's delves into its features, specifications, and benefits of our advanced PCB, highlighting its suitability for various industries.
Understanding RO4003C Material
Rogers RO4003C is a proprietary woven glass reinforced hydrocarbon/ceramic laminate that combines the best properties of traditional materials. It offers the electrical performance of PTFE materials while maintaining the manufacturability of epoxy/glass laminates. The dielectric constant of 3.38 ± 0.05 at 10 GHz ensures optimal signal integrity, making it ideal for high-frequency applications.
One of the key advantages of RO4003C is its low dissipation factor—0.0027 at 10 GHz and 0.0021 at 2.5 GHz—allowing for minimal signal loss.
This characteristic is particularly beneficial in applications that require precise signal transmission, such as telecommunications and radar systems.
