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: Double Sided PCB Built On 10 mil 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 10mil RO4350B substrate with Tg 280°C for the
application of radar RF. Its finished thickness is 0.3mm and 1oz copper. White silkscreen and
green solder mask covers both sides and immersion gold plated are on pads. 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;
Excellent high frequency performance due to low dielectric tolerance and loss;
Long storage time,it can be stored for more than 1 year in vacuum bag;
SMT process is resistant to reflow soldering, resistant to rework;
16000 square meter workshop;
UL, ISO14001, TS16949 certified;
Strict WIP inspection and monitoring as well as working instruction;
Quick CADCAM checking and free PCB quotation;
Competitive price;
Application
Balanced mixer, Pphotocoupler,Sound control switch induction,Multicoupler
