PCB Blog - Intrduction of Rogers PCB

Rogers PCB material is a hard and dense material that can be used to manufacture printed circuit boards. The board contains an epoxy resin core, metal-plated copper, and aluminum. The surface is coated with aluminum. It has good size and advantages in terms of thermal expansion coefficient, which can effectively control the magnitude of temperature stress to ensure the stability of component performance. It can be widely used for high-frequency power distribution and circuit boards such as CPUs, switches, connectors, etc.

Rogers PCB is a high-frequency board produced by Rogers Company. It is different from traditional PCB boards - epoxy resin (FR4). It has no glass fiber in the middle and uses a ceramic base as a high-frequency material. Rogers has superior dielectric constant and temperature stability. Its dielectric constant and thermal expansion coefficient are very consistent with copper foil, which can be used to improve the shortcomings of polytetrafluoroethylene substrate. It is very suitable for high-speed electronic design, commercial microwave and RF applications. Its low water absorption is an ideal choice for high humidity applications, providing customers in the high-frequency board industry with the highest quality materials and related resources, fundamentally improving product quality.

Why choose Rogers PCB?

Rogers PCB VS FR-4 Material

FR-4 material is cheaper than Rogers material.

Compared with FR-4 material, Rogers material has high high-frequency performance.

3. FR-4 material has a higher Df or dissipation coefficient than Rogers material and suffers greater signal loss.

In terms of impedance stability, Rogers material has a wider range of Dk values than FR-4 material.

In terms of dielectric constant, the Dk of FR-4 is about 4.5, which is lower than the Dk of Rogers material, which is about 6.15-11.

In terms of temperature management, Rogers material has less variation compared to FR-4 material.

Rogers PCB is a high-performance high-frequency circuit board widely used in fields such as communication, electronics, and satellite navigation due to its excellent dielectric properties, reliability, and excellent mechanical properties. The dielectric constant of Rogers PCB board is very stable, able to work over a wide temperature range, has excellent high-temperature resistance, and can operate normally in complex environments with stable accuracy. In addition, the Rogers PCB board also has extremely high rigidity and wear resistance, which can ensure the mechanical properties of the circuit board and ensure its normal operation under harsh conditions.
