RO4835 PCB By Feature
Using this material, the need to reduce signal distortions in devices is answered. This makes it an Impedance Control PCB.
This type of laminate makes it possible to obtain the desired threshold for impedance measurements suitable for High Frequency boards.
Aside from being used in RF circuits, this type of material is equally useful for related products like point-to-point connectors. RF applications need precision in signal integrity.
Specific devices for high-speed applications will not function without the use of High Tg, for example, those used in telecom tools.
This material is a really suitable product for Multilayer PCBs, ranging from 4-Layer to 40 Layer PCB, even 3-Layer PCB.
In order to ensure quality, rigid PCBs must be examined thoroughly; this is particularly true for more expensive Rogers material.
What is RO4835 Material in PCB?
The RO4835 is a part of Rogers Corporation’s line of RO4000 laminates.
This material is hydrocarbon ceramic in composition.
It does not require specific via treatment like the other ceramic PCBs because of this special composition.
Even though the material is intended for high frequency use, Rogers markets this product as being FR4-process friendly, which lowers the cost.
It’s similar to high-end high frequency materials composed of ceramic and/or PTFE, also produced by Rogers.
The RO4835 boasts of its effectiveness in delaying oxidation.
What are the Advantages of Using RO4835?
The benefits of using the material on your boards are as follows:
- Less expensive compared to Rogers 5870, 5880, 6002 and 6006
- In the same way as the other, more expensive Rogers products, you can use it in Microwave and RF applications.
- It carries the UL 94 V-O certification for flame resistance.
- Wonderful performance for Plated Through Hole board designs
- Useful for multilayer PCB stack-ups with a 4, 5, 8 and higher layer count
Applications that Use RO4835
This material is used in a wide-range of circuit boards.
The following sectors of industry are applicable:
- Automotive applications – such as toll collection, GPS, navigation & safety
- RF applications – including short-range and long-range communication
- Power applications, especially amplifiers with high voltage capacity
- Military use – missile guidance & telemetry systems
Since these are advanced applications, the PCBs you order should be handled carefully by seasoned engineers and staff who follow hygienic procedures.

The most economical PCB material is the FR4 laminate and prepreg.
- However, the R04835 is preferable to it due to the following reasons.
- It can be utilized for high-frequency circuits because of its low dielectric loss.
- It is a mechanically robust material because of its dimensional stability.
- In contrast to some FR4 materials, it is CAF resistant.
However, there is a similarity between the RO4835 and FR4.
This cutting-edge Rogers material works with FR4 procedures such as automated handling systems for FR4 copper clad material.
Some PTFE and Ceramic PCB devotees have switched to using RO4835 laminates and prepreg.
- It is because, despite having performance characteristics comparable to those of Rogers’ High Frequency materials, this Rogers material is more affordable.
- It is possible to use the Rogers 4000 series for microwave applications.
- Excellent heat performance, similar to PTFE and Ceramic PCB.
- You can also install blind via and buried via on the RO4835. SMD mounting and BGA mounting are both options.
Lastly, RO4835 is as customizable as its premium counterparts.
