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
The temperature coefficient of dielectric constant is among the
lowest of any circuit board material, making it ideal for
temperature sensitive applications;
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;
Reducing signal loss in high frequency application meets the
development needs of communication technology;
Low in-plane expansion coefficient;
Excellent dimensional stability;
Products and Manufacturing are certified by authorized
organizations;
UL, ISO14001, TS16949 certified;
On-time service;
More than 15 years of PCB experience;
Application
UHF radio, power divider, Relay Stations, base station antenna
