Hybrid PCB | Mixed Material 4-layer PCB Made On 20 mil RO4350B + FR4 With Blind Via

(Printed circuit boards are custom-made products, the picture and parameters shown are just for reference)


Layer 1 to layer 2 is the core of 20mil (0.508mm) RO4350B high frequency material, the signal transmission lines are on first layer copper, then layer 3 to layer 4 is another core of epoxy glass material. The 2 cores are bonded by a sheet of adhesive (prepreg).


20mil RO4350B+FR4 PCB


Basic specifications:


Layer count: 4 layers

Panel: 75mm x 82mm = 1 type = 1 piece

Stackup 0.508mm RO4350B_FR4


Features and benefits:  


1) The temperature coefficient of dielectric constant is among the lowest of any circuit board material, making it ideal for temperature sensitive applications;

2) RO4350B exhibits a stable dielectric constant over a broad frequency range. This makes it an ideal substrate for broadband applications;

3) Signal integrity performance improvement over the stack-ups with all FR4 board;

4) ISO9001, ISO14001, IATF16949, UL Certified factory

5) Prototype to mass production capability;


Applications:


Mixer, Radar data acquisition converter, Spread spectrum, Duplexer
