Abstract

The invention relates to the technical field of PCB manufacturing and production, in particular to a PCB and a manufacturing method thereof. The PCB includes a heat dissipation substrate, and a firstcircuit layer, a second circuit layer and a third circuit layer arranged in turn on the heat dissipation substrate. A heat dissipation insulating dielectric layer is arranged between every two adjacent circuit layers. Each circuit layer is electrically connected with the other circuit layers through electricity conduction and heat conduction connectors. The third circuit layer is provided with anouter line which is electrically connected with the third circuit layer through a connector. The heat dissipation substrate and the insulating dielectric layer of the PCB have both the functions of insulation and heat dissipation, and the connectors have the functions of electricity conduction and heat conduction. Each circuit layer is electrically connected with the other circuit layers through connectors, and a smooth heat dissipation channel is formed. Therefore, the PCB has a better heat dissipation effect, which is conducive to high integration of electronic products.

Description

technical field [0001] The invention relates to the technical field of PCB board manufacturing and production, in particular to a PCB board and a manufacturing method thereof. Background technique [0002] The Chinese name of PCB is printed circuit board, also known as printed circuit board. It is an important electronic component, a support for electronic components, and a carrier for electrical connections of electronic components. Because it is made using electronic printing, it is called a "printed" circuit board. At present, the development trend of electronic products is high performance and miniaturization, which puts forward corresponding requirements for the PCB board as the support body of electronic components, requiring the PCB board to be as small as possible in size and high in integration. At the same time, as the functions of electronic components loaded with chips increase, the power of the chips increases, and more and more heat is generated on the PCB. If...
