Abstract

The invention relates to a high heat radiating circuit substrate and a manufacturing method thereof. The high heat radiating circuit substrate comprises a conducting wire layer, an insulating layer and a graphite heat conducting layer, wherein at least one electronic component can be arranged on the conducting wire layer, and wires are arranged on the conducting wire layer for connecting the electronic component; the insulating layer is positioned at one side of the conducting wire layer; and the graphite heat conducting layer is arranged at one side of the insulating layer and can uniformly radiate the heat generated by the electronic component. The manufacturing method of the high heat radiating circuit substrate comprises the following steps: firstly, using a metallic substance or an alloy thereof to manufacture the conducting wire layer; secondly, forming at least one wire on the conducting wire layer; thirdly, using an insulating substance to manufacture the insulating layer; andfourthly, jointing the graphite heat conducting layer to the other side of the insulating layer. Since the heat conducting layer of the high heat radiating circuit substrate and the manufacturing method thereof use the graphite material, not only the manufacturing cost can be reduced, but also the heat can be radiated uniformly to increase the heat radiating rate, and the like.

Description

【Technical field】 [0001] The invention relates to the field of circuit boards and manufacturing methods, in particular to a high heat dissipation circuit substrate and a manufacturing method thereof. 【Background technique】 [0002] As oil prices continue to rise, there is a trend of energy saving and carbon saving, in order to reduce energy consumption and slow down the speed of global warming. [0003] In order to save energy and carbon, manufacturers from all over the world have taken full advantage of their rights to launch various energy-saving and carbon-saving products. For example, automobile manufacturers launch hybrid vehicles or electric vehicles; and electrical appliance manufacturers launch various environmentally friendly appliances or lamps. Among them, the most popular What is optimistic about is LED lamps, such as LED street lamps or LED bulbs. According to research, the use of LED street lamps or LED bulbs can greatly reduce power consumption, so that the p...
