High frequency board refers to special circuit boards with high electromagnetic frequency, used in the field of high frequency (frequency greater than 300MHZ or wavelength less than 1 meter) and microwave (frequency greater than 3GHZ or wavelength less than 0.1 meters) PCB, is a circuit board produced by using part of the process of the manufacturing method of ordinary rigid circuit boards or by using a special treatment method on the copper-clad laminated boards of the microwave substrate. Generally speaking, High frequency board can be defined as the frequency of 1GHz or more circuit boards.

Since its founding in 1912, Isola has been an industry leader in the development and manufacture of laminated copper-clad laminate substrates. They have an optimal balance between cost and performance when selecting substrates. Key factors that microwave and millimeter wave board designers must consider when selecting high speed RF or microwave laminates include dielectric thickness, dielectric constant and loss factor, as well as small tolerances between batches.


High frequency PCB boards are characterized by their excellent transmission performance in High frequency operating environments. At the same time, the board thickness of High frequency boards is thinner, and the line width and line spacing are finer than those of ordinary PCB circuit boards. In addition, the dielectric constant of High frequency boards is particularly small, so it can reduce signal loss and improve signal transmission rate and reception sensitivity. High frequency PCB boards generally use materials such as RO4350B, RO4003C and F4B.
