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.

General description
This is a type of double sided PCB built on 10mil RO4350B substrate with Tg 280°C for
the application of antenna. It's 0.3mm thick finished with white silkscreen over green solder
mask and immersion gold are plated on pads. The base material is used from Rogers Corp.,
entire board supplying 1 up per panel. They're fabricated per IPC 6012 Class 2 using supplied
Gerber data. Each 100 panels are packed for shipment.
Features and benefits
A. The temperature coefficient of dielectric constant is among the lowest of any circuit board
material, making it ideal for temperature sensitive applications;
B. Delamination of copper foil will not be caused by the change of cold and heat due to the
consistency with the thermal expansion coefficient of copper foil;
C. Reducing signal loss in high frequency application meets the development needs of
communication technology;
D. Low in-plane expansion coefficient;
E. Excellent dimensional stability;
F. Products and Manufacturing are certified by authorized organizations;
G. UL, ISO14001, TS16949 certified;
H. On-time service;
I. More than 15 years of PCB experience;
Application
UHF radio, power divider, Relay Stations, base station antenna
