RO4450F By Thickness and Panel
The 20 mil Thickness that we integrate into this laminated board has been considered a standard density in the industry; it can hold an almost average type of components. In addition, they can be ideal for compact radio devices.
The 40 mil Thickness that we incorporate in this laminated board is still part of the standard density in the industry; however, it is already capable of withstanding almost heavy components. Thus, they are used in the industrial sector.
The 16″ X 18″ (406 X 457mm) panel size that we integrate into this laminated board can be ideal for small to medium average-size devices, including automotive, wearables, and medical apparatus; it is commonly partnered with multilayer board type.
The 24″ X 18″ (610 X 457mm) panel size that we incorporate in this laminated board is suitable for applications that are on average size devices. In addition, you can pair this size into different thicknesses depending on the purpose.
The 24.5″ X 18.5″ (622 X 470mm) panel size that we integrate into this laminated board is highly compatible with almost large-size devices, including aircraft and marine controls. In addition, it can be paired with different thicknesses.
The 24″ X 36″ (610 X 915 mm) panel size that we incorporate in this laminated board can support large-size devices, such as aerospace and other industrial equipment. Similar to the different sizes mentioned previously, it is suitable for any thickness.
What is RO4450F?
As mentioned previously, the Rogers RO4450F falls under a dielectric material that is combined with FR4 cores and prepreg that acts as a way to enhance the quality and performance of the traditional FR4 multilayered design.
Additionally, glass-reinforced hydrocarbon/ceramic laminates from the same line of dielectrics have been employed in layers where RF, microwave frequency, dielectric constant (DK), or high-speed signal demands call for superior materials. In less essential signal layers, FR-4 cores and prepreg are still frequently employed.
