Brief Introduction
RO4350B High Frequency Circuit Material is glass reinforced hydrocarbon/ceramic laminates
(Not PTFE) designed for performance sensitive, high volume commercial applications. Currently
Double sided and multilayer RO4350B PCB's are available at Bicheng company. Double sided
RO4350B PCB with thickness 10mil (0.254mm), 20mil (0.508mm), 30mil (0.762mm) and 60mil
(1.524mm) are the bestsellers. We provide prototype runs, small batches and volume production
Services.

Advantages
1) Excellent high frequency performance due to low dielectric tolerance and loss;
2) Excellent dimensional stability.
3) Low thermal coefficient of dielectric constant;
4) Low Z-Axis expansion;
5) Low in-plane expansion coefficient;
6) Stable electrical properties verus frequency;

Applications
1) Attenuator, Automatic gate induction;
2) LNB's for direct broadcast satellites;
3) Microstrip antenna, spread spectrum;
4) Microstrip and cellular base station antennas and power amplifiers;
5) RF identifications tags
6) Spread spectrum communications systems
7) Trunk amplifier, splitter module etc.


PCB Case: RO4350B 60 mil High Frequency PCB
Immersion Gold
(PCB's are custom-made products, the picture and parameters shown are just for
Reference)

General description
this is a type of high frequency PCB built on RO4350B for the application of LTE. It's a
2 layer RF PCB board at 1.6 mm thick. It's immersion gold finish with solder mask and
Silkscreen from Taiyo. It's fabricated per IPC 6012 Class 2 using supplied Gerber data.
Each 10 boards are packed for shipment. 


Features and benefits
the temperature coefficient of dielectric constant is among the lowest of any circuit board
Material, making it ideal for temperature sensitive applications.
RO4350B exhibits a stable dielectric constant over a broad frequency range. this makes it
An ideal substrate for broadband applications.
RO4003C exhibit a stable dielectric constant over a broad frequency range. this makes it
An ideal substrate for broadband applications.
ENIG has long storage time (It can be stored for more than 1 year in vacuum bag)
Whole fabrication processes are totally controlled.
