Rogers RO4400 Series(RO4450F, RO4450T, and RO4460G2) dielectric materials have long been used in combination with FR-4 cores and prepreg as a means to achieve a performance upgrade of standard FR-4 multi-layer designs.
Rogers RO4003C, Rogers RO4350B, and Rogers RO4000 LoPro glass reinforced hydrocarbon/ceramic laminates have been used in layers where RF/microwave frequency, dielectric constant (DK), or high-speed signal requirements dictate high-performance materials. FR-4 cores and prepreg are still commonly used to inexpensively formless critical signal layers.
