Rogers 4350 Can Be Used in Satellite Communications

Rogers 4350 is a glass-reinforced hydrocarbon and ceramic laminate that’s frequently used in high-frequency circuit boards. Its superior electrical properties, including a stable dielectric constant around 3.48, enable RF circuits to operate with precise impedance control and minimize signal distortion.

The material also offers robust temperature stability, allowing electronics to function under harsh conditions. These characteristics make Rogers 4350 a powerful choice for applications such as 5G infrastructure, radar systems, and satellite communications.

A dielectric is an insulator that slows down or stops electricity flow when it encounters an electric field, preventing electrostatic discharge and the consequent destruction of equipment. rogers 4350 superior dielectric performance enables it to block more energy than other PCB materials, such as FR-4 and fiberglass, protecting circuitry from damage caused by over-voltage. The low dielectric loss of the material also improves its ability to disperse heat, which is important for RF and microwave components that may require high levels of thermal management.

Exceptional dimensional stability allows circuits built with the material to maintain their integrity over a range of temperatures and operating conditions. This durability enables a higher level of reliability in aerospace and automotive electronics, reducing maintenance costs and overall operational downtime. It is also highly compatible with a range of fabrication methods, making it easy for engineers to produce reliable and consistent boards in mass production programs.

Ultrathin PCBs made with Rogers 4350 have significantly reduced thicknesses, enabling sleek and compact electronic devices that can fit into tight spaces without sacrificing performance. They also have low loss tangent and consistent dielectric constant throughout their rated frequency range, ensuring efficient signal transmission with minimal distortion.

Rogers 4350 is available in a variety of pre-pregs, laminates, and bondplies that provide flexibility for the circuit board designer. However, it’s critical to discuss required deliverables, tolerances, testing needs, volumes and any other special considerations with a trusted manufacturing partner to get accurate pricing quotes.

Combining a mix of Rogers 4350 and standard FR-4 substrates in a hybrid circuit board enables designers to optimize cost, performance, and reliability. This approach allows them to design the outermost layers using Rogers materials for maximum efficiency, while utilizing traditional FR-4 for inner and center layers to reduce overall assembly costs.

Mixed medium PCBs can also simplify the manufacturing process by eliminating the need for separate high-frequency and conventional layers, which lowers component counts, assembly time, and potential points of failure.

Engineers designing a hybrid circuit board with Rogers 4350 should carefully plan the layer stackup to ensure that high-frequency signals propagate effectively through the Rogers layers, while routing low-frequency components through the FR-4 layers. A seasoned fabrication partner will be able to advise on the most strategic layer stackup, leveraging the unique properties of each material to create a high-performance, reliable, and robust PCB. Ideally, the top and bottom layers of the PCB should be composed of the higher-frequency Rogers materials to maximize signal transmission quality and prevent interference between layers.
