Abstract

The invention provides a multilayer HDI printed circuit board capable of rapidly dissipating heat. Heat generated by working of a circuit board body is transmitted to a heat conducting plate through a heat conducting layer of the circuit board body and finally transmitted to an annular heat conducting pipe. And the pressure pump works to enable the refrigerant to circularly flow among the annular heat conduction pipe, the output heat conduction pipe and the backflow heat conduction pipe. The refrigerant transmits heat of the annular heat conduction pipe to the output heat conduction pipe and the backflow heat conduction pipe. On one hand, the heat conduction plate, the annular heat conduction pipe, the output heat conduction pipe and the backflow heat conduction pipe can effectively dissipate heat, and on the other hand, the cooling fan works to accelerate the heat dissipation process of the output heat conduction pipe, so that the temperature of a refrigerant flowing through the output heat conduction pipe is reduced, and the refrigerant with the reduced temperature flows into the annular heat conduction pipe again. According to the multilayer HDI printed circuit board capable of rapidly dissipating heat, heat dissipation processing can be efficiently carried out on the circuit board body in an air cooling mode and a water cooling mode at the same time, normal work of all electronic elements can be guaranteed, and the service life of the circuit board body is prolonged.

Description

technical field [0001] The invention relates to the field of circuit board processing, in particular to a fast heat dissipation multi-layer HDI printed circuit board. Background technique [0002] A printed circuit board, also known as a printed circuit board, is a provider of electrical connections for electronic components. The printed circuit board is mostly represented by "PCB", and its development has a history of more than 100 years. The design of circuit boards is mainly layout design. The main advantage of using circuit boards is to greatly reduce wiring and assembly errors, and improve the automation level and production labor rate. According to the number of layers of the circuit board, it can be divided into single-sided, double-sided, four-layer, six-layer and other multi-layer circuit boards. Before the advent of printed circuit boards, the interconnections between electronic components depended on the direct connection of wires to form a complete circuit. In...
