High frequency speed PCB substrate material
At present, the production and development of epoxy printed circuit board (PCB) substrate materials for high-speed, high-frequency, has become the world’s epoxy printed circuit board (PCB)

manufacturers, as well as epoxy printed circuit board (PCB) substrate material substrate manufacturers an important issue. China Epoxy Resin Industry Association experts said that more in-depth

research on the theory and characteristics of high-speed and high-frequency substrate materials, understand the development progress of foreign countries and achieve the best choice and

application of such substrate materials in the manufacture of epoxy resin printed circuit board (PCB). It is a very important and necessary technical work that needs to be carried out at present. pcb

Above, the experts of China Epoxy Resin Industry Association discussed the varieties and characteristics of high-speed and high-frequency substrate materials and how to evaluate and select them.

Its discussion focuses on the common aspects of the two characteristics of “high speed” and “high frequency”. China Epoxy Resin Industry Association experts said that combined with the actual in-

depth study, you can also get the understanding on the other hand – the particularity between them pcb processing multi-layer pcb circuit board four-layer pcb board.

In the development of high-speed and high-frequency substrate materials selection and application by epoxy resin printed circuit board (PCB) manufacturers, in order to solve technical difficulties

and reduce manufacturing costs, PCB designers and manufacturers are forced to have more and broader understanding and grasp the characteristics of high-frequency circuits of substrate materials.

At the same time, it is necessary to master the characteristics of high-speed transmission of substrate materials. And understand, grasp the difference between the two aspects. According to their

differences (that is, the special aspect) to more accurately grasp the principle of selecting the substrate material suitable for it pcb processing multi-layer pcb circuit board four-layer pcb circuit

board.

At present, many epoxy printed circuit board (PCB) manufacturers have realized from theory and practice that when selecting the substrate material used in PCB for high-frequency circuits, special

attention should be paid to the characteristics of the substrate material to investigate its tan delta and how the characteristics change at different frequencies. When the PCB focuses on the

requirements of high-speed signal transmission, or the PCB focuses on the requirements of high precision control with characteristic impedance, it should focus on the ε characteristics of the

substrate material used and other performance conditions under changes in frequency, humidity, temperature and other conditions. China Epoxy Resin Industry Association experts said that some

of the world’s substrate material manufacturers, on the basis of further in-depth understanding of this aspect, but also timely development and market suitable for high-speed and high-frequency

series of low ε and low tanδ varieties of pcb.
