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: Immersion Gold PCB On 30 mil RO4350B With Double Layers
(Printed circuit boards are custom-made products, the picture and
parameters shown are just for reference)
General description
This is a type of double sided PCB built on high frequency
substrate with Tg 288°C for the application of 4G WiFi Module. It's
0.8 mm thick, white silkscreen over green solder mask. All via's
are open to air. Pads are plated by immersion gold. The base
material is used from Rogers RO4350B, entire board supplying 1 PCB
up. They're fabricated per IPC 6012 Class 2 using supplied Gerber
data. Each 25 panels are packed for shipment.
Features and benefits
The dielectric constant (DK) is low and stable, so the signal
transmission is good without delay;
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;
Excellent dimensional stability;
Good high temperature and low temperature resistance(-192℃-260℃);
UL recognized and RoHS Directive-compliant;
Electrical test and high voltage test;
Impedance control test and solder-ability test;
Micro-section and thermal stress test;
Reliability test, insulation resistance test and ionic
contamination test;
Meeting your PCB needs from prototype to mass production;
Application
Low noise amplifier, acoustic detection sensors, Optoelectronic
Transmitters, 4G antenna
