Method for implementing single point grounding design, single-point grounding PCB package and printed circuit board

Abstract

The invention discloses a method for implementing a single point grounding design, a single point grounding PCB package and a printed circuit board. The method comprises the steps that a PCB is provided and at least comprises a signal layer and a main horizontal layer; the single-point grounding PCB package is designed on the PCB, including a single-point grounding device and a single-point grounding vent hole; the single-point grounding device is arranged on the main horizontal layer, and is communicated with the horizon of the main horizontal layer; the single-point grounding vent hole runs through the signal layer, is communicated with the single-point grounding device, and is isolated from the signal region in the signal layer; and the single-point grounding PCB package is called when single-point grounding design is required to implement. Therefore, single-point grounding is used as an independent device for processing, and the device is provided with graphic symbols corresponding to a schematic circuit diagram and a package structure corresponding to PCB, so that standard design and automatic processing of single-point grounding can be realized, and the design efficiency and reliability of PCB can be improved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method for realizing a single-point grounding design, a single-point grounding PCB package and a printed circuit board. Background technique [0002] As more and more functions are integrated in the design of various electronic products, there are more and more designs for integrating baseband, radio frequency, audio, power management and other module circuits on a printed circuit board (PCB). In these module circuits, most of the baseband circuits are digital circuits; while most of the circuits such as radio frequency, audio frequency, and power management involve analog circuits. In the design scheme with both digital circuits and analog circuits, it is usually necessary to use single-point grounding for low-frequency circuits such as analog and audio, that is, to connect the ground wires of each circuit module to the main ground plane at a certain point. .
