a printed circuit board

Abstract

The invention provides a printed circuit board and relates to the technical field of printed circuit boards. The printed circuit board includes a printed circuit board body, the outer surface of the printed circuit board body is uniformly provided with a plurality of first conductive contacts, and one side of the outer surface of the printed circuit board body is fixedly connected with a first cable The first cable connector is embedded with a conductive cable, and the side of the conductive cable away from the printed circuit board body is provided with a fixed protective cover. The turbo cooling fan on the air guide fixed cover starts to be energized and rotates, and the cold air from the outside is continuously sent into the inside of the air guide fixed cover through the fan-shaped exhaust cover, and the cold air is blown between the copper fins through the fan-shaped exhaust cover , so that it is convenient to complete the heat that is derived from the surface of the heat dissipation copper plate cover from the chip through the exhaust port, and then achieve heat dissipation to the printed circuit board body, which is beneficial to prolonging the service life of the printed circuit board body and the entire electronic device.

Description

technical field [0001] The invention relates to the technical field of printed circuit boards, in particular to a printed circuit board. Background technique [0002] Printed circuit board, also known as printed circuit board, is a provider of electrical connections for electronic components. Its development has a history of more than 100 years. Its design is mainly layout design. The main advantage of using circuit boards is that it greatly reduces wiring and Assembly errors improve the automation level and production labor rate. According to the number of layers of circuit boards, they can be divided into single-sided boards, double-sided boards, four-layer boards, six-layer boards and other multi-layer boards. [0003] At present, the existing printed circuit boards have heat dissipation problems. Due to the physical reason that part of the electric energy will be converted into heat energy when circulating on the printed circuit board, the printed circuit board itself wi...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a printed circuit board, which solves the problem that the printed circuit boards in some relatively large electronic devices with stacked internal structures will be caused by the accumulation of closed electronic components. The heat accumulation problem of the printed circuit board heat dissipation itself
