Power supply layer of multilayer circuit board and circuit structure of computer system

Abstract

The invention discloses a source layer containing the power block with smooth arc edge. It provides a multilayer circuit board, which includes at least a grounidng layer, at least a signal layer containing multiple traces to transmit signals, at least a source layer containing multiple power blocks, used to provide multiple voltage levels, and at least a connection hole, used to link the traces with the source or grounding layer. The adjacent power blocks with different voltages levels is separated by the insulating line which contains multiple first separating line segments and multiple smooth-curve second separating line segments, the second one used to link with adjacent first one whose tangent included angle is larger than a preset angle.

Description

technical field [0001] The present invention relates to a power supply layer of a multi-layer printed circuit board, in particular to a power supply layer including a power supply block with smooth arc-shaped boundary and a circuit structure of a computer system. Background technique [0002] Generally speaking, a printed circuit board (PCB) has been commonly used to assist the electrical connection between various electronic components, so as to facilitate the transmission of signals by the various electronic components. In the past, the printed circuit board was a single layer with only one signal plane on its surface, and the traces on the signal layer were used to connect all the mounts on the printed circuit board. The electronic component, that is, the output or input signal of the electronic component is transmitted through the trace. However, when a plurality of different signals are included between the electronic components, the signal layer...

Problems solved by technology

[0005] like image 3 As shown, the insulated line itself can be regarded as the boundary of the power supply block 32. Since the insulated line is not a smooth curve at the turning point, an acute angle will be generated at the boundary of the two adjacent power supply blocks 32a, 32b, and 32c. Adjacent power supply blocks 32 provide different voltage levels, so there is a voltage difference between two adjacent power supply blocks 32, so the acute angle of its boundary will further produce the effect of tip discharge, thus causing the voltage level of the power supply block 42 Because the power supply block 32 is used to provide the operating voltage of the computer components, if the operating voltage is unstable, it will cause fluctuations in the signal level and affect the stability of the overall system
