WebThe Dielectric Constant is a convenient way of discussing the permittivity of materials. Recall that the permittivity of a vacuum (that is, in outer space or where there is no atoms or material in a volume - also known as Free Space) is 8.854*10^-12 [Farads/meter]. Suppose the permittivity of a material such as FR4 is to be determined. WebThe dielectric constant of FR4 is a vital determinant of mechanical and thermal reliability. As a result, FR4 dielectric constants are a critical component of circuit boards used in high-temperature environments, such as engine compartments. Luckily, modern PCB designers can perform FR4 simulations using Altium Designer.
