Rogers PCB Stackup vs. FR-4
Key Differences in Stackup Design
When it comes to stackup design, Rogers PCBs and FR-4 boards are like apples and oranges. Each material serves its own niche, particularly in high-frequency applications. Understanding these differences can make or break a project, especially for engineers looking to maximize performance.
Dielectric Properties Rogers materials typically feature lower dielectric constants than FR-4, which is crucial for minimizing signal loss at high frequencies. For instance, while FR-4 generally has a dielectric constant of around 4.5, Rogers materials can have values as low as 3.0. This difference allows for tighter control of impedance and improved signal integrity.
Layer Configurations The configuration of layers in Rogers PCBs is also distinctly different. While FR-4 boards might use a simpler two-layer or four-layer setup, Rogers designs often employ multi-layer configurations to handle complex RF designs. For example, a typical Rogers stackup may include multiple microstrip and stripline layers, which optimize performance in dense circuitry.
| Feature | Rogers PCB | FR-4 Board |
| Dielectric Constant | Typically 3.0 or lower | Around 4.5 |
| Layer Configurations | Multi-layer options for RF applications | Simpler configurations, usually 2-4 layers |
| Signal Loss | Lower due to advanced materials | Higher, especially at high frequencies |
Temperature Stability Rogers materials are also designed to withstand higher temperatures without losing performance. For instance, while standard FR-4 can start to deform at temperatures above 130°C, Rogers materials can operate effectively at temperatures up to 200°C or more. This is particularly advantageous in applications like aerospace and telecommunications, where thermal stability is key.
Rogers PCB Stackup vs FR4
Rogers PCB layers can be mixed together with FR4 layers to provide better performance at a minimum cost vs. all layers are Rogers materials. If this is the case, then the signals must be placed on the Rogers PCB core, not on the prepreg.
A common FR4 6-layer stack-up is illustrated below. The prepreg is located in the outer layer to lower costs since prepreg has cheaper than cores. This is commonly referred to as”foil build”
But it is the case that when the Rogers layer is required, the core is placed on the layers that require it, which are typically the outer layers. Check out the example below that has three cores instead of two, like the example above. This type of configuration is often called”Cap Construction “, Cap Construction” board or”core build” “core build”.
