With the development of electronic technology, the production of electronic products also requires more and more materials, such as high frequency PCB materials. Take Rogers, for example. Rogers PCB board is a high frequency board manufactured by Rogers. It is different from the traditional PCB board epoxy. There is no glass fiber in the middle which is ceramic based high frequency material. When the circuit frequency is higher than 500MHz, the range of materials available to design engineers is greatly reduced. Rogers RO4350B material can easily make RF engineering design circuit, such as network matching, transmission line impedance control, etc.

Due to its low dielectric loss, R04350B has advantages over ordinary circuit materials in high frequency PCB applications. The dielectric constant of temperature fluctuation is almost the lowest in the same material. In the wide frequency range, the dielectric constant is also very stable at 3.48. 3.66. The LoPra copper foil design recommendation reduces insertion loss. This makes the material suitable for broadband applications.
RO3000 series: Based on ceramic filled PTFE circuit material, models: RO3003, RO3006, RO3010, RO3035 high-frequency laminates. RT6000 series: ceramic filled PTFE circuit material, designed for high dielectric constant electronic and microwave circuits, model: RT6006 permittivity 6.15/ RT6010 permittivity 10.2. TMM series: ceramic, hydrocarbon, thermosetting polymer, model: TMM3, TMM4, TMM6, TMM10, TMM10i, TMM13i composite materials.
According to the data show that at present make the high frequency PCB commonly used board in our country the PCBs are: Rogers HT800, Rogers 6002, Rogers 5880 circuit board, Rogers 5880 board, Rogers 5880, Rogers 4701, Rogers 4350 B, Rogers 4003 C, Rogers 4003, FR4+Rogers mixed mination etc.
