    PTFE High Frequency PCB F4B Microwave PCB

    Hello everybody,

    Today we talk about F4B (PTFE) high frequency circuit board.


    F4B is a series of PTFE based high frequency materials which is brand of China. It has advantages on price and quality in the application of navigation, radar, satellite communication, 4G communications, 5G communications and the like.


    The common dielectric constant available are 2.2, 2.55 and 2.65, other value of dielectric constants are 2.17, 2.45, 2.75 and 3.0 etc; Copper weight available are 0.5oz, 1oz and 2oz and 3oz; the thickness of board ranges from 0.17mm to 5.0mm.
