What is Rogers PCB?
Rogers PCBs are high-frequency boards that can be used for femtoampere current circuits. It is different from the conventional PCB board—epoxy resin (FR4). It has no glass fiber in the middle and uses a ceramic base as the high-frequency material. Rogers has superior dielectric constant and temperature stability. Rogers PCBs are made from ceramic-reinforced PTFE or hydrocarbon ceramic laminates, which can minimize current leakage.
Why Rogers PCB is used?
- Low current leakage
- Rogers PCBs can minimize current leakage, which is the unintended flow of electric current between conductive elements on a PCB.
- High-frequency
- Rogers PCBs are high-frequency boards that are suitable for microwave and ultra-high-speed digital circuits.
- Temperature stability
- Rogers PCBs have superior temperature stability compared to conventional PCB boards.
- Dielectric constant
- Rogers PCBs offer a wide range of dielectric constants.
Various Rogers PCB materials
- RO4000 Series: Woven glass reinforced hydrocarbon ceramic laminates with a range of dielectric constants
- RT/duroid 6000 Series: Woven glass reinforced PTFE composites with low dielectric loss
- RO3000 Series: Woven glass reinforced ceramic filled PTFE composites
- Rogers 5880: Glass-reinforced PTFE that gives good low current and stray capacitance
- Rogers 3003: Ceramic-reinforced PTFE that is soft and bendable.
