Rogers PCB are hydrocarbon ceramic laminates and prepares offer superior high frequency performance and low cost printed circuit fabrication resulting in a low loss material which can be fabricated using standard epoxy/glass (FR-4) processes. Rogers material is also referred as RO4000. It is used in PCB designs where power management, signal integrity and impedance matching is very crucial. Most common application, where Rogers Material is used are: high-speed designs, RF, microwave, mobile applications, etc.
Rogers PCB used dielectric material which is poor conductor of electricity. It is used as insulating layer on regular FR-4 based PCB. Some examples of di-electric are Porcelain, mica, glass, plastics and some metal oxides are good dielectrics.
The prime advantage of dielectric materials are: low di-electric loss, low signal loss, low cross-over and cross talks. It is also very cost effective to manufacture them. Again, they can be fabricated as thin as 0.1mm and compatible with other substrate like FR-4.
Rogers dielectric PCB materials are perfect for RF applications and mobile phone design. They are also used is flexible PCB design. RO4000 material possesses the properties needed by designers of RF microwave circuits and matching networks and controlled impedance transmission lines. RO4000 series laminates offer a range of dielectric constants (2.55 – 6.15), are available with UL 94 V-0 flame retardant versions.
