The Rogers RO4000 series high-frequency PCB materials are a range of laminates specifically designed for high-performance RF (radio frequency) and microwave applications. These materials offer excellent electrical performance, including low dielectric constant (Dk), low loss factor (Df), stable dielectric properties, and good thermal conductivity. Due to their superior electrical performance and ease of processing, RO4000 series materials are widely used in high-performance electronic devices, particularly in the RF and microwave sectors.
Features of Rogers RO4000 Series High-Frequency PCB Materials:
Non-PTFE, low loss, low tolerance, and excellent high-frequency performance.
Stable electrical properties at different frequencies.
Low dielectric constant temperature coefficient.
Low Z-axis thermal expansion coefficient, low in-plane expansion coefficient.
Excellent dimensional stability, suitable for mass production.
Material Composition of Rogers RO4000 Series High-Frequency PCB: The materials are made from a fiberglass-reinforced hydrocarbon/ceramic substrate (non-PTFE) and are designed for high-performance, mass-market applications. RO4000 series materials combine high-frequency performance with low PCB production costs, offering the low loss and processing similar to standard FR4 materials, making them highly cost-competitive.
Stable Performance of Rogers RO4000 Series: When the circuit operates at frequencies above 500MHz, the range of material choices for designers is significantly reduced. RO4000 series materials enable RF engineers to easily design circuits, such as filter re-designs, network matching, and impedance control for transmission lines.
Thanks to their low dielectric loss characteristics, RO4000 series materials outperform ordinary circuit materials in high-frequency applications. The temperature coefficient of dielectric constant is among the lowest in its class, and its dielectric constant remains stable across a wide frequency range, making it ideal for broad frequency applications.
Low Thermal Expansion Coefficient: The thermal expansion coefficient (CTE) of RO4000 series materials offers several benefits to circuit designers. Because the CTE closely matches that of copper, it ensures excellent dimensional stability. This is especially important in multilayer circuit designs. Even under severe thermal shock conditions, the low Z-axis CTE of RO4000 series materials ensures the quality of plated vias.
