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 ºC;
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
