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: Antenna PCB Built On 10mil RO4350B With
Immersion Gold on Both Sides
(Printed circuit boards are custom-made products, the picture and parameters shown are just
for reference)
General description
This is a type of high frequency PCB built on 10mil (0.254mm) RO4350B substrate with Tg 280°C
for the application of RF antenna. It's double sided board at 0.30 mm thick, white silkscreen over
green solder mask on bottom side and immersion gold is on pad for soldering. The base material
is from Rogers Corp, entire board supplying 1 PCBs per panel. They're fabricated per IPC 6012
Class 2 using supplied Gerber data. Each 50 panels are packed for shipment.
