What is Rogers PCB material
Before we introduce about the RO4350B, we need to know about the Rogers PCB and materials. Rogers PCB board is a material produced by Rogers Company dedicated to high-frequency PCB and RF PCB. It is different from traditional printed circuit board epoxy resin. No glass fiber in the middle is a ceramic-based high-frequency material, and has excellent dielectric constant and temperature stability, making it ideal for harsh environments exposed to extreme temperatures and vibrations, and can be widely used in high-frequency power distribution and circuit boards of CPUs, switches, connectors, etc.
The materials of Rogers series is mainly classified as RO3000 series, RT6000 series and TMM series. In addition, RO4350B in the RO4000 series has advantages over ordinary circuit materials in high-frequency applications due to its low dielectric loss, and the dielectric constant of temperature fluctuations is almost the lowest in the same material.
What is RO4350B material
What is the advantage of RO4350B
RO4350B ensures good thermal stability, achieves the optimization of cost and high frequency performance, and is the most cost-effective low-loss high-frequency plate. The dimensional stability and high reliability of the whole product in PCB processing and assembly will bring more benefits to the design of multilayer circuits.
1- Low RF loss: Df: 0.0037@10GHz
2- Low dielectric constant: Dk: 3.48+/-0.05 and fluctuate with temperature
3- Low expansion coefficient
4- Low dielectric constant tolerance
5- Excellent dimensional stability
6- Stable electrical characteristics.
7- The processing technology is similar to FR-4, and it is easy to mass produce and multi-layer mixing of FR4, so it has a great price competitive advantage
What is the application of RO4350B
Rogers is a high-frequency board material produced by Rogers in the United States, which is mainly used in radar, communications, aviation and other high-frequency and high-speed PCB fields. Among them, Rogers RO4350B meets the requirements of commercial-grade equipment manufacturers for high-frequency microwave RF PCBs as a hydrocarbon/ceramic laminate with a dielectric constant of 3.48. The following are specific application areas：
RF and microwave products
Cell base station antennas
Microwave point-to-point connection (P2P)
Automotive radar and sensors
Radio frequency identification (RFID) tags
High frequency head (LNB)
Communication and satellites
What is the dielectric constant of RO4350B
The dielectric constant (Dk: 3.48+/-0.05) of Rogers RO4350B high-frequency sheet has tight tolerance control, low loss characteristics (Df:0.0037@10GHz), easy to mass produce CAF resistance (ion migration resistance), and RO4350B processing technology can be the same as standard epoxy/glass cloth.
What is the thickness of RO4350B
Comparison of parameters of high-frequency laminate Rogers RO4003C and RO4350B
RO4003C and RO4350B both are glass-cloth-reinforced ceramic/hydrocarbon laminates that are widely used in RF/microwave frequency circuits or high-speed signals where dielectric constant (Dk) stability is required. There are many factors that should be considered when choosing a board when designing a circuit board. The following is the parameter table of Rogers RO4003C and RO4350B, I hope it can help you choose.
