Microwave pcb Circuit Boards General informationMicrowave define: Microwaves are electromagnetic spectrum allocations by definition it refers to the wavelength range from 1m to 0.1mm electromagnetic waves, the corresponding frequencies from 0.3GHz to 3000GHz. This electromagnetic spectrum includes decimeter (frequency from 0.3GHz to 3GHz) \ centimeter wave (frequency from 3GHz to 30GHz) \ millimeter wave (frequency from 30GHz to 300GHz) and sub-millimeter wave (frequency from 300GHz to 3000GHz, some literature This paragraph does not contain the definition of microwave) four bands (including caps, excluding the lower limit). Like having light resistance, like the sound of nature, penetrating, non-ionizing, informative five characteristics. So most of microwave field must use high frequency pcb(＞1GHZ),means microwave pcb must use high frequency printed circuit boards(rogers/Taconic/arlon/isola etc) XCEPCB are professional manufacturer in high frequency pcb Generally high frequency pcb have rogers and Teflon(Taconicand f4b)Microwave pcb information: Base materialRogers 4350Board THK0.8mmLayer2Board size9*12cmSurface finishImmersion goldLine space6milCopper THK1OZLine width6milMicrowave pcb material: Rogers4003C: thickness(0.254 0.508,0.813,1.524) DK 3.38 Rogers4350B: thickness(0.254 0.508,0.762,1.524) DK 3.5 Rogers5880: thickness(0.254 0.508,0.762) DK 2.2 Rogers3003: thickness(0.127,0.508,0.762,1.524) DK 3 Rogers3010: thickness(0.635) DK 10.2 Rogers3206: thickness(0.635) DK 10.2 Rogers3035: thickness(0.508) DK 3.5 Rogers6010: thickness(0.635,1.27) DK 10.2
