Problems solved by technology

[0005] In view of the fact that in the prior art, metal-based printed circuit boards (MCPCB; Mental Core PCB) are usually used to solve the problem of heat dissipation, but the technology of metal-based printed circuit boards is mostly limited to single-sided single-layer, single-sided double-layer Or double-sided single-layer and other thin-film PCB structures cannot be applied to multi-layer circuit boards with more than 4 layers

Abstract

The invention relates to a high heat conduction apparatus for a multilayer circuit. The high heat conduction apparatus comprises a heat conduction substrate, a multi-layer circuit board, and a chip packaging module. The heat conduction substrate includes a setting surface and at least one boss protruded from the setting surface. The multi-layer circuit board is arranged at the heat conduction substrate and has at least one through hole; and the boss passes through the through hole correspondingly. The chip packaging module has at least one hear radiation zone and a plurality of pins; the heat radiation zone is contacted to the boss correspondingly; and the pins arranged around the heat radiation zone are electrically connected to the multi-layer circuit board.

Description

technical field [0001] The present invention relates to a high heat conduction device of a multilayer circuit, especially a kind of perforation through which a boss of a heat conduction substrate is inserted in a multilayer circuit board, so that a chip package module is arranged on the boss and the multilayer circuit board. High thermal conductivity device for layer circuits. Background technique [0002] With the increasingly sophisticated technology development, LED lighting technology has become increasingly mature and has become a necessity for human daily life. However, its power consumption and heat generation will also increase significantly. If the heat cannot be effectively reduced or dissipated, the brightness of the LED will decrease and the deterioration of the components will be accelerated. Therefore, the quality of the heat dissipation substrate is an important part of LED thermal management. [0003] In the existing technology, the metal printed circuit boa...
