Cost is the first difference to consider in this section. The ultimate goal of any PCB manufacturer is to introduce a cost-effective circuit board with the best performance. FR4 PCB is the most affordable PCB on the market. This is effective if your design is for the best conditions with low frequency and nominal temperature settings. If your application requires high-speed or extreme temperature operation, you may have to ignore the cost and choose the expensive Rogers PCB.
Impedance stability is the next difference between FR4 and Rogers PCB. The dielectric constant of the substrate is one of the important factors that define the impedance and stability of the circuit board. The higher the dielectric constant, the higher the impedance stability. Although FR4 is the cheapest substrate available, its maximum dielectric value is 4.5. And Rogers PCB has a higher and wider dielectric value range, such as 6.5 to 11. This feature makes Rogers PCB the best choice for high-heat applications where stable impedance is critical.
Thermal management remains a critical consideration in PCB design, especially in high-speed applications where PCBs generate significant heat. A reliable thermal management system is essential for efficient heat dissipation. Among the available options, the thermostat-based laminate in Rogers PCB stands out as the most suitable choice due to its ability to withstand high temperatures. In contrast, FR4 PCBs are not suitable for high-temperature environments and should be avoided in such applications.
The dissipation factor, which indicates signal loss in the PCB, is significantly lower in Rogers PCB compared to FR4 PCB. The loss factor of FR4 PCB is 0.02%, whereas Rogers PCB boasts a mere 0.004% signal loss. As a result, Rogers PCB offers improved performance with minimal signal loss compared to FR4 PCB.
Moisture absorption directly impacts the electrical and thermal properties of the PCB substrate material, ultimately affecting circuit board performance. With its minimal moisture absorption, Rogers PCB excels in providing consistent efficiency under varying environmental conditions.
When considering application and performance, FR4 PCB is a solid choice for medium and low frequency applications, offering durability, good electrical stability, and compatibility with various manufacturing processes in the PCB industry. On the other hand, Rogers PCB is better suited for specialized applications such as space applications, thanks to its superior performance characteristics including temperature stability and low outgassing. In critical applications like space and aerodynamics, Rogers PCB emerges as the top choice for ensuring reliability and performance.
