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;


Mixer, Radar data acquisition converter, Spread spectrum, Duplexer
