Stable dimensional stability: With a CTE that is closely aligned with copper, Rogers 4350 offers exceptional dimensional stability and accuracy, even over long periods of time. This is important for high-speed digital and RF circuits that must maintain a stable connection between copper layers to prevent unwanted electromagnetic interference (EMI).
Low cost: Compared to other microwave materials, such as FR-4, Rogers 4350 is less expensive because it does not require a special fabrication process. In addition, it is fully compatible with lead-free solders and standard assembly processing like etching and spray painting.
Enhanced tensile strength: The unique combination of fiberglass and ceramic filler in the Rogers 4350 core provides superior tensile strength that can withstand the stresses of high-speed digital and RF circuits. Its higher glass content also provides improved bending and twisting endurance, helping ensure that the printed circuit board will not warp under the strain of high-speed signals.
Its high-temperature resistance also helps prevent the oxidation of copper which can occur at high temperatures. This oxidation is an undesirable effect that can lead to decreased reliability and increased failure rates in high-speed electronic components, such as processors and memory.
Rogers 4350 is used in a variety of communication and industrial applications, including cellular base stations, 5G infrastructure, and radar systems. Its ability to withstand high-speed signal transmission and low loss tangent enable the fast data throughput necessary for advanced wireless communication networks. It is also a preferred choice for aerospace electronics, such as avionics and satellite payloads, where precise signal processing and durability are paramount. Moreover, Rogers 4350B is often utilized in medical devices such as MRI machines and ultrasound systems to improve diagnostic and treatment capabilities.
