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 20mil (0.508mm) High Frequency
PCB Immersion Gold
(Printed circuit boards 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 20 mil substrate for the application
of interference filter. It's a 2 layer RF PCB board at 0.6 mm thick. It's immersion gold finish
with green solder mask and white silkscreen. It's fabricated per IPC 6012 Class 2 using
Supplied Gerber data. Each 10 boards are packed for shipment. 


Features and benefits
