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: High Frequency PCB Built On 60mil RO4350B
With 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 double sided PCB built on high frequency material with Tg 280°C for the application
of satellite receiver. It's 1.60 mm thick, no solder mask on top layer and bottom layer, immersion gold
covering pads on top side and entire bottom side. The base material is used from RogersCorp.,
60mil (1.524mm) RO4350B, entire board supplying single up. They're fabricated per IPC 6012
Class 2 using supplied Gerber data. Each 25 boards are packed for shipment.
Features and benefits
The temperature coefficient of dielectric constant is among the lowest of any circuit board
material, making it ideal for temperature sensitive applications;
Good high temperature and low temperature resistance(-192ºC-260ºC);
Superior corrosion resistance;
Low thermal coefficient of dielectric constant;
Low Z-Axis expansion;
Delivery on time: >98%
Customer complaint rate: <1%
No quality complaint is meant to save money;
No MOQ, low cost for prototypes and small runs quantity;
Free stencil shim sent for new user;
Application
Preamplifier, Photocoupler, Relay Stations, Base station antenna
