Fortunately, its effect can be minimized by reducing the number of discontinuities in a circuit design, and by carefully weighing the choice of circuit substrate material in terms of thickness and dielectric constant, where thinner materials and higher dielectric constants can both contribute to lower .
PCB materials can degrade signal power in three ways: radiation losses, dielectric losses, and conductor losses. Losses through radiation of EM energy largely depend on the circuit architecture, so even the lowest-loss PCB material may not save a circuit configuration that has a tendency to radiate energy., Considerations when choosing the thickness of Rogers 5880 material 1.Electrical Properties Electrical properties are one of the primary considerations when selecting material thickness.The dielectric constant (Dk) of Rogers 5880 helps reduce delay and loss in signal propagation., Common Rogers PCB Stackup Structures. Common Rogers PCB stackup structures often include combinations of these configurations, tailored to specific applications. For instance, a typical Rogers stackup might feature several layers of Rogers material sandwiched between standard prepregs, optimizing performance while managing costs., Rogers PCB is used to describe PCBs manufactured from Rogers PCB material, a high-performance laminate for use where stable electrical properties are needed. In contrast to the conventional FR-4 based on glass fabric and epoxy resin, Rogers materials use ceramic-filled PTFE or hydrocarbon resin systems., , .
