Problems solved by technology

[0004] However, cutting the power layer can only suppress low-frequency noise, but cannot isolate high-frequency resonance noise
The high-frequency resonance noise that has not been eliminated will cause incomplete signals transmitted by the circuit board, or generate electromagnetic interference and other problems

Embodiment Construction

[0020] The power layer board of the following embodiments can transmit DC potential and effectively filter out high-frequency noise.

[0021] Please refer to FIG. 1 , which is a power layer board according to an embodiment of the present invention. The power layer board 100 includes a first circuit block 109 and a second circuit block 111 coupled thereto. Each circuit block can be a printed circuit board. When the potential signal is transmitted from the input terminal (noise terminal) 113 to the receiving terminal (disturbed terminal) 115, the noise can be filtered out.

[0022] The length 101 of the first circuit block 109 and the length 105 of the second circuit block 111 are related to the noise frequency to be filtered. The relationship between the length 101 and the length 105 and the noise frequency is:

Abstract

The invention discloses a power supply layer plate, which provides a DC potential and filter noise on the power supply layer plate. The power supply layer plate includes a first circuit block and a second circuit block. The length of the first and second circuit blocks is related to frequency of the noise to be filtered. The second circuit block is coupled with the first circuit block, and the width of the second circuit block is bigger or smaller than that of the first circuit block.

Description

technical field [0001] The invention relates to a power laminate and a manufacturing method thereof, in particular to a power laminate capable of suppressing high-frequency noise and a manufacturing method thereof. Background technique [0002] In high-speed digital circuits, when high-speed signals pass through unideal transmission paths such as signal vias or discontinuous signal reference planes, noise will be caused between power layer boards and ground planes. Noise from the power plane / ground plane can also propagate to other locations in the digital circuit in the form of parallel plate waveguides. [0003] In order to avoid the influence of the noise between the power layer board / ground plane on the electronic components on the digital circuit, the power layer board is traditionally cut, that is, the circuit board that provides power is cut, and then connected to the cut circuit board with a conductor or a coupling capacitor. Between the circuit boards to filter out...
