In the world of high-performance electronics—particularly in RF (Radio Frequency) and Microwave applications—"Rogers PCB" is a name that commands respect. For many engineers, it is not just a brand; it is synonymous with high frequency, high speed, and superior reliability.
This guide provides an in-depth look at Rogers PCBs, comparing them with standard materials and providing a detailed specification list of Rogers materials available at NextPCB.
A Rogers PCB refers to a printed circuit board manufactured using laminates produced by the Rogers Corporation. Unlike traditional FR-4 boards, which use epoxy resin and glass fiber, Rogers laminates are typically based on ceramics, hydrocarbons, or PTFE (Polytetrafluoroethylene) composites.
These materials are engineered to maintain extremely low signal loss and a highly stable Dielectric Constant (Dk) even at very high frequencies (up to 110 GHz).

While Rogers materials come at a higher cost than standard FR-4, they offer specific performance characteristics that are non-negotiable for designs operating above 500MHz.
| Feature | Rogers Material (e.g., RO4350B) | Standard FR-4 | Performance Impact |
|---|---|---|---|
| Frequency | Ideal for > 1GHz (RF/Microwave) | Typically < 1GHz | Rogers maintains signal clarity at high frequencies. |
| Dissipation Factor (Df) | Very Low (~0.0037) | Higher (~0.020) | Rogers minimizes signal transmission loss. |
| Dielectric Constant (Dk) | Stable & Precise | Fluctuates | Rogers allows for precise impedance control. |
NextPCB Expert Tip: To balance performance and budget, consider a Hybrid Buildup. Use Rogers material for critical signal layers and standard FR-4 for power/ground layers.

At NextPCB, we understand that selecting the right material is the first step to a successful RF design. NextPCB’s PCB manufacturing capabilities cover both PTFE and non-PTFE Rogers laminates for consumer to extremely high-frequency applications.
Below is a list of the most popular Rogers materials we support. For other low-loss options, you can also view our high-speed materials.
