Abstract

The present invention provides a PCB for inhibition of a transmission line weaving effect and a design method thereof. The PCB comprises a transmission dielectric layer which is provided with a transmission line, the transmission dielectric layer comprises a fiberglass piece and adhesive piece materials, the fiberglass piece is formed by weaving glass fiber yarns, the weaving densities of the glass fiber yarns are a length X and a width Y, the window sizes of the adhesive piece materials between the glass fiber yarns is a length A and a width B, distances a pair of difference lines P and N inthe transmission line comprises a distance in a parallel direction and a distance in a vertical direction, the distance in the parallel direction is A+X value, and the distance in the vertical direction is B+Y value to ensure the impedance matching of the difference lines P and N. According to the PCB for inhibition of the transmission line weaving effect and the design method thereof, the impedance line width is designed according to the weaving density of the transmission dielectric glass fiber yarns to solve the design difficulty of a current PCB transmission line, inhibit the weaving effect and ensure the integrality and signal propagation quality of high-speed signal transmission.

Description

technical field [0001] The invention relates to a PCB board, in particular to a PCB board and a design method for suppressing the weaving effect of transmission lines. Background technique [0002] As the system architecture becomes more and more complex and the signal rate is higher and higher, the signal integrity of the high-speed bus becomes more and more important. How to ensure that the PCB board design has the least impact on the signal integrity of the high-speed signal? The first thing to consider, the layout design of the transmission line on the PCB is the top priority of optimization. [0003] The common transmission line on the PCB is an etched copper wire, and the transmission medium is underneath the transmission line. Different transmission media can be characterized by relative permittivity. The relative dielectric constant around the transmission line determines the transmission delay of the signal on the PCB board. The higher the dielectric constant, the...
