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: Dual Layer PCB On 30 mil RO4350B With Immersion ROHS
Compliant
(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 WiFi attenuator.
It's 0.8 mm thick, white silkscreen over green solder mask. All
via's are open to air. Pads are covered 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
RO4350B exhibits a stable dielectric constant over a broad
frequency range. This makes it an ideal substrate for broadband
applications;
Tg > 280 ℃;
Stable electrical properties verus frequency;
Low thermal coefficient of dielectric constant;
Low Z-Axis expansion;
High solderability, no stressing of circuit boards and less
contamination of PCB surface;
SMT process is resistant to reflow soldering, resistant to rework;
30000 square meter month capability;
Application
GPS antenna, directional coupler, spread spectrum, Tower Mounted
Amplifier
