相对介电常数在无线电通信中的应用 相对介电常数(Dielectric Constant),也称为介电系数,是衡量材料在电场中存储电能能力的一个物理量。在无线电通信领域,这一参数对信号的传输、天线的设计以及电磁兼容性等方面 2025-01-10 10:15:10 指导可穿戴PCB设计的基本原理 如果可穿戴 PCB 应用需要高速、高频材料,FR4 ...
The dielectric constant plays a crucial role in a wide range of applications. In capacitors, it determines the ability of the material between the plates to store electrical energy. Higher dielectric constant materials allow for increased energy storage, which is desirable in applications such as hig...

Dielectric Constant and Dissapation Factor of Fr4 Laminates Produced Using Specific Vendors of Fiberglass YarnCurrently there is not a specification within the IPC for the DK and DF of E-Glass reinforcements and there is no requirement to report the DK and DF of the glass formulation used to ...
Since this is a classification of materials, the compositions of FR4 variants, and thus the requirements for cutting the material, can differ significantly. Due to the composition, for example, the material properties in terms of water absorption, melting temperature or dielectric constant can vary ...
