Rogers substrate PCB price and FR4 PCB price are the first differences to consider. The ultimate goal of any PCB manufacturer is to introduce cost-effective PCB prototypes with optimal performance. FR4 PCB prototypes are the most affordable PCB prototypes on the market. If your design is optimised for low frequency and temperature rated settings, it is wise to use FR4 PCB prototypes. If your application requires a high-speed PCB or extreme temperatures, you may have to overlook the price of Rogers PCBs and opt for an expensive Rogers PCB prototype.
Impedance stability is another difference between FR4 PCB prototypes and Rogers PCB prototypes. The dielectric constant of a Rogers substrate PCB is one of the most important factors in determining the impedance and stability of the PCB. The higher the dielectric constant of the Rogers PCB prototype, the higher the impedance stability. Although FR4 is the cheapest PCB prototype available, it has a maximum dielectric value of 4.5. Roger PCBs have a higher and wider range of dielectric values, for example, Rogers PCB dielectric constants range from 2.2 to 16. The dielectric constant characteristics of Rogers PCBs make Rogers PCBs the choice of Rogers PCB laminates for use in high heat dissipation applications where impedance stability is critical. for high heat dissipation applications where impedance stabilisation is critical.
Thermal management is also the difference between Rogers PCB prototypes and FR4 PCB prototypes. In high-speed PCB applications, PCB prototypes generate significant heat that must be handled carefully with a good thermal management system. In this case, thermostat-based laminates in Rogers PCBs are the best choice. FR4 PCBs cannot withstand high temperatures and therefore cannot be used in these applications.
The dissipation factor indicates the signal loss in the PCB. Rogers PCBs have much lower signal loss compared to FR4 PCBs. The FR4 PCB has a loss factor of 0.02% while the Rogers PCB has a loss factor of 0.004%. Therefore, Rogers PCBs provide reliable results with minimal electrical signal loss compared to FR4 PCBs.
The moisture absorption of Rogers PCB prototypes is directly related to the electrical and thermal properties of the substrate material. This in turn affects the effectiveness of the PCB prototype. Rogers PCBs have the least amount of hygroscopicity so it can provide optimum efficiency in a variety of environmental conditions.
The application and effectiveness of Rogers PCBs is based on overall effectiveness. FR4 PCBs are considered the lowest cost PCBs and Rogers substrate PCBs excel in performance. Therefore, FR4 PCBs are best suited for low to medium frequency applications. They are rugged, well balanced in terms of power stability, and PCBs can be easily fabricated in virtually any process available in the PCB industry. Roger substrate PCBs are suitable for applications with advanced performance requirements.
