Abstract

The invention relates to a PCB (Printed Circuit Board), comprising a conduction layer (1), an insulation layer (2) and a heat radiation layer, wherein the three layers are sequentially fixed from top to bottom. The PCB is characterized in the heat radiation layer is a carbon layer (6) which is in a plate-shaped structure formed by pressing a carbon material. The PCB provided by the invention has a better heat radiation property and is convenient to install.

Description

technical field [0001] The invention relates to the technical field of PCB board heat dissipation, in particular to a PCB board with a heat dissipation structure. Background technique [0002] PCB (Printed Circuit Board), the Chinese name is printed circuit board, also known as printed circuit board, printed circuit board, is an important electronic component, a support for electronic components, and a provider of electrical connections for electronic components. PCB boards are widely used in the prior art. It is well known that electronic components will generate heat during work, so the heat dissipation of the PCB board is an important indicator. Taking the single-sided PCB board commonly used in the prior art as an example, as attached figure 1 As shown in , it includes a conductive layer 001, an insulating layer 002, and a heat dissipation layer 003 (it also includes conventional layers such as a printing layer during specific implementation). The insulating layer 002 ...
