What is a Rogers PCB
Laminates manufactured by Rogers Corporation are used to make PCB boards. This board is often compared to FR4, the difference is that instead of epoxy and fiberglass, ceramic, teflon materials are used. Even though it is more expensive to make printed circuit boards using Rogers material, it is still considered the first choice for many projects. FS Technology gives the following reasons:
- Rogers’s performance index is the world’s top
- This material has strong compatibility
- Meet the demanding requirements of high-frequency PCBs
- Single-layer, double-layer, and multi-layer circuit structures can be constructed
- These boards have extremely low water absorption and are therefore considered the best option for wet environments
Types of Manufacturable Rogers PCBs
Rogers RO3003 is a high frequency laminate mainly used in RF and microwave applications. Its main constituent material is a ceramic-filled Teflon (PTFE) composite.

- 3003 PCB can be used in high temperature electrical projects due to its lower dielectric losses.
- It is an economical laminate that can minimize your project costs
Because the 3003 has the above advantages and characteristics, it is very suitable for use in oscillators, bandpass filters and advanced driver assistance systems (ADAS).
The 4003 laminate uses 1080 and 1674 glass fabrics having the required arrangements similar to lamination of electric features. The most special thing about 4003C is that the electrical properties of 4003C are very close to PTFE/woven glass cloth material, but its processing technology is similar to epoxy resin/glass cloth material. It can be removed using a traditional nylon brush.

Rogers 4003 PCB excels in high frequency circuits and is the best choice if your project is an application that requires the use of frequency values in excess of 300 Megahertz.
Does your project have special requirements on PCB signals? I believe the HF Rogers 4350 can meet your requirements. This type of Rogers is made of fiberglass (not PTFE) reinforced hydrocarbon resin/ceramic filler. Since RO4350B laminates do not require special THT through hole processing like PTFE’s microwave materials, it is less expensive than conventional microwave laminates. Many PCB designers complete their projects with the excellent RF performance and cost-effective board provided by the Ro4350.

- RO4350 material passes UL 94V-0 fire rating required for high voltage RF design
- Higher transmission frequency and faster signal throughput
- Rogers 4350 has the lowest temperature coefficient of dielectric constant of all PCBs
The RO4700 G3 is an antenna grade laminate that is a more economical alternative to PTFE antenna material by using ceramic hydrocarbons with less lossy copper. The RO4700 G3 PCB is more compatible with traditional FR-4 and high temperature lead-free soldering processes and does not require through-hole preconditioning. Due to its light weight and high TG value, about 80% is used for antenna processing.
- Dielectric constant of 2.55 or 3.0 +/- 0.05

- When the components are introduced into the transmission system, it will cause the loss of PCB transmission power (Insertion Loss). The 4730G3 is better in this regard, allowing the component to experience less power variation on the load before and after insertion.
The RO4830 circuit board is a thermoset laminate that can be constructed using FR4 standard technology. Common circuit boards have relatively large changes in dielectric constant due to the special weaving structure of glass fibers, especially at millimeter-wave frequencies. To study the effect of glass weaving on the antenna performance, we fabricated a cross-fed microstrip patch array antenna on RO4835 and RO4830 PCBs. Unsurprisingly, the electrical properties of the RO4830 laminate were more in line with the standard values, with better reflectance (S11 <–10dB) and boresight gain performance.

- The oxidation resistance capability of RO4830 laminate is the best among hydrocarbon based materials
RO4835 is a circuit board material specially created by Rogers for the inner layer design of multi-layer boards. This thermoset pair can slow down the increase in dielectric constant and dissipation factor of the wiring due to oxidation. Compared to traditional thermosets, RO4835T is ten times more resistant to oxidation. From a project perspective, this material is the best combination of price, performance and durability. As a member of the Ro4000 series of hydrocarbon materials, it is also outstanding in providing high frequency performance.

Rogers RT/duroid 5880 High Frequency Laminate is a combination of PTFE composite and microfiber. These fibers maximize fiber gain, providing the most valuable direction for circuit manufacturers and end applications. The performance index of this kind of 5880 filled with short glass fibers in PTFE resin is the world’s top.

Comparison of rogers pcb with other materials
Rogers is a commonly used high frequency laminate material and is therefore often compared to other types of circuit boards. FS Technology lists several circuit boards and compares them in the following article.
Rogers pcb vs FR-4
- The prices of rogers are higher than FR4 PCB
- There are fewer signal losses for roger PCB than the FR4 due to less dissipation factor
- Roger PCB can handle the high temperatures environment than other boards
- The value of the dielectric constant for roger is high than FR4 which is about 2.5 to 11 for roger and FR4 has 4.5.
Rogers pcb vs Taconic
These two boards come with features of fewer power losses and are used in high-frequency applications. But in the case of efficient Taconic is considered as best than roger PCB. But these two are used in electrical and power transmission circuits but rogers are used for circuits where less frequency is needed.
These two boards are also used for high-temperature conditions with that both come with features of reduction of electric noise for high-performance applications
common problem for rogers pcb
The common problem of roger PCB is temperature. The projects where rogers boards have to apply will explain the temperature requirements for boards. If you are creating projects that have a sensitive nature to the temperate used to make the design can handle the suitable rogers boards. If you do not consider the template measures for the board and projects will disturb the operation of your board as well as projects where it applied. Before using the Roger PCB make sure that the board has high value of temperate than the board where roger has to be applied otherwise board will damage if temperatures increases
All details have been covered for the Rogers PCB that is good for high frequency and temperature applications circuits. It sued for antenna communications systems aviation, and industry. It comes with different types that have their own features and parameters for applications. Before using the Roger PCB make sure that you have selected the temperature of boards larger than the projects where it has to apply otherwise can affect the circuit operation.
