What is the difference between FR 4 material and Rogers material?

 The difference between FR-4 material and Rogers material
1. FR-4 material is cheaper than Rogers material.
2. Compared with FR-4 material, Rogers material has a very high frequency.
3. The Df or dissipation factor of FR-4 material is higher than Rogers material, and the signal loss is greater.
4. In terms of PCB impedance stability, Rogers material has a larger Dk value range than FR-4 material.
5. For the dielectric constant, the Dk of FR-4 is about 4.5, which is lower than the Dk of Rogers material (about 6.15 to 11).
6. In terms of temperature management, compared with FR-4 material, Rogers material has less changes.

Why use Rogers PCB material?
FR-4 material provides the basic standard for PCB substrates, maintaining a broad and effective balance between cost, durability, performance, manufacturability and electrical characteristics. However, because performance and electrical characteristics play an important role in your design, Rogers Materials has the following advantages:
PCB low electrical signal loss
low cost pcb manufacturing
Low dielectric loss
Better thermal management
Dk (dielectric constant) has a wide range of values (2.55-10.2)
Low outgassing in aerospace applications
Improve PCB impedance control
