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(-192ºC-260ºC);
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
