Rogers 4350 contribute to impedance control
When working with high-frequency PCBs, precision materials are key for impedance control. Rogers 4350 provides a wide range of properties that enable PCB designers to accurately model and predict circuit behavior, eliminating costly design iterations caused by material parameter variations.
The RO4350B series of Rogers laminates are ideal for high-speed traces with low loss tangents, which are essential for achieving the performance requirements of modern electronic devices. The precise dielectric constant of these materials helps ensure that the impedance is matched to the required value, which enables PCBs to work at higher speeds with more stability and reliability.
Unlike traditional microwave laminates such as FR-4, which have significant variation in their dielectric constant properties over frequency and temperature conditions, rogers 4350 laminates offer consistent, stable dielectric constants with tolerances of +-0.05 across all lots and panels. This consistency enables high-frequency circuits to achieve electrical performances that closely match simulations, reducing costly iterations in design.
How does Rogers 4350 contribute to impedance control
The precise dielectric constant of the Rogers 4350b peel laminate also enhances the efficiency of electromagnetic waves that pass through the substrate. This is especially important for high-speed signals, such as those used in data transmission and radar systems.
Its high withstand voltage and insulation performance can help prevent current leakage, which can cause equipment damage or fires. In addition, it can prevent current overload, which can result in the destruction of copper foil and conductive patterns. These characteristics make rogers 4350b peel pcb suitable for use in many different applications.
Rogers microwave materials are widely used in commercial wireless, aerospace, and defense applications where precise materials are critical to reliable operation. Their robust constructions withstand the harsh environments of space and combat the challenges of radiation, outgassing, and thermal shifts. They are also highly compatible with the rigorous requirements of military and aerospace standards, enabling unambiguous functionality.
Compared to conventional FR-4, the dielectric constant of 4350b rogers is lower, which enables more efficient signal transmission and reduces the delay in the signal propagation process. Moreover, it can be fabricated using standard PCB manufacturing techniques, including etching, solder resist, and solder reflow. Additionally, it is compatible with conventional aluminum and pressed phenolic entry and exit materials for vias, and its surfaces can be bonded to standard direct-screened and photo-imageable copper.
High-performance printed circuit boards (PCBs) made with a 4350b rogers peel pcb can support 5G NR connectivity and ADAS (advanced driver assistance system) functionality, as well as mmWave radars. These radars rely on microwave components based on Rogers materials to meet mmWave performance requirements, enabling collision avoidance and other advanced features.
High-performance mmWave and radars require high-speed connectivity and a stable structure. Rogers PCB materials are engineered to deliver the speed, reliability, and performance necessary for mmWave and radar systems, with the stability to withstand vibration and radiation. The material’s low-temperature expansion and high-frequency performance enables radars to operate in challenging environmental conditions, such as in crowded spaces or in moving vehicles. Moreover, it can be fabricated with a standard FR-4 process, without the need for special pre-treatments for through-hole copper plating or plasma treatments for PTFE plates.
