RO4350B + FR4 high frequency hybrid PCB

Überblick

Rogers RO4350B PCB material is a strengthened glassy hydrocarbon/ceramic material that can be processed in the same way as low cost printed circuits on FR-4 substrate material.

Dielectric Properties

Dielectric Constant

Its dielectric constant at 10 GHz is 3.48, which makes it commonly used in high frequency power amplifier designs.

Thermal Stability

Low CTE Along the Z-Axis

The RO4350B laminate has a low coefficient of thermal expansion (CTE) along the z-axis, ensuring high stability for multilayer circuits interconnected through metallized vias (PTH).
