RF board stands for Radio Frequency Printed Circuit Boards. The frequency for RF board is normally between 300MHz ~ 3GHz, or much bigger, so normally FR4 board cannot meet the requirements, so we need to use special material to achieve the high frequency and we named this kind of boards as RF boards. RF board is excellent in high frequency performance due to its low dielectric tolerance and loss of material.

RF board is ideal for applications with higher operating frequency requirements. Right now, we normally use following material:

• Rogers. (Copper from 1/4 OZ to 2 OZ). Click here for PDF file for "Rogers-High-Frequency-Circuit-Materials" such as RO4233, RO4350, RO4003, and so on.
• PTFE (Dupon Telfon)

The fabricate process is similar like FR4, but the copper plating is more complex than FR4, because material characteristics, it’s much harder to metalize the through hole (copper plating), and other process is complex than FR4, so need unique handling method and experienced workers.
