Flexible copper clad laminates are used in flex and rigid-flex circuits because of their mechanical properties.The FCCL circuit application is in low transmission frequency,high-frequency dielectric properties such as dielectric constant(Dk) and dielectric loss tangent(Df) which are paid less attention...
DK is the abbreviation of dielectric constant, and it can be represented by ε and εr. DK's definition can be the ratio of the capacitance of a capacitor containing a dielectric to the capacitance of a vacuum capacitor of the same volume. Its calculation formula is below: DK represents a...
Dielectric constant of water is 70 and this number will be increased when substrate absorbs more moisture. Thus, modification of impedance control will lead to badly-performed signal transmission. e. Copper foil should conform to relatively high peel strength that mustn't be compromised just due ...
摘要: In the design of high-frequency (or fast-impulse) capacitors required to hold off high voltages, one can use high-dielectric-constant materials (e.g., certain ceramics). This paper considers some of the high-frequency problems of such capacitors and techniques to mitigate them....
A region of dielectric dispersion has been found in ferroelectric lead titanate zirconate ceramics at frequencies about 1Gc/sec. The losses associated with the dispersion are quite high, the dissipation factor rising to about 0.4 at 2Gc/sec. The magnitude of the dispersion is halved in the measu...
This study focuses on the effect of different dielectric properties in the design of 3-dB planar branch line coupler (BLC) using RT5880, RO4350, TMM4 and RT6010, particularly at high frequency of 26 GHz, the fifth generation (5G) operating frequency
This means that the increase in the capacitance 𝐶𝑑Cd proportional to the dielectric constant reduced the magnitude of the impedance. Since the impedance is also affected by the dynamic characteristics of the PESA, the difference in impedance under condition (b) to those under conditions (a)...
