The RO4350B hydrocarbon ceramic laminate from Rogers has been developed for high-frequency, low cost applications. The laminate can be fabricated into printed circuit boards using standard FR-4 circuit board processing techniques. Unlike PTFE based high performance materials, this series of laminates do not require specialized via preparation processes such as sodium etch. This material is a rigid, thermoset laminate that is capable of being processed by automated handling systems and scrubbing equipment used for copper surface preparation.
The RO4350B laminate has a Dk of 4, Df of 0.0031 to 0.0037 and can be used up to frequencies of up to 40 GHz. It can be used to develop RF & microwave circuits, matching networks and controlled impedance transmission lines.
