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: RO4350B 30 mil Double Sided PCB 1oz Copper
Immersion Gold
(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 RO4350B 30 mil substrate for the application
of combiner. It's a 2 layer RF PCB board at 0.8 mm thick. It's immersion gold finish with green
solder mask and white silkscreen. It's fabricated per IPC 6012 Class 2 using supplied Gerber
data. Each 10 boards are packed for shipment.
Features and benefits
The characteristic of low dielectric loss makes the signal loss at a lower level, which makes
the signal transmission of the whole equipment excellent.
Heat resistance, chemical resistance, impact strength and peeling strength are good.
The temperature coefficient of dielectric constant is among the lowest of any circuit board
material, making it ideal for temperature sensitive applications.
ENIG has long storage time (It can be stored for more than 1 year in vacuum bag)
Make delivery on time keeping 98% on-time-delivery rate.
Products and Manufacturing are certified by authorized organizations.
More than 15 years' experience
Fast and flexible to save the time of production from prototype to standard production
UL recognized and RoHS Directive-compliant
Application
LNA, WiFi amplifier, RF Switches, Trunk amplifier
