Abstract

The invention discloses a heat dissipation device of a multilayer circuit board. The heat dissipation device comprises a plurality of circuit board bodies with the same specification, the circuit board bodies are provided with a plurality of electronic chips, a plurality of heat dissipation rods and at least one heat radiator, one ends of the heat dissipation rods are attached to the electronic chips; and the other ends of the heat dissipation rods sequentially pass through the multilayer circuit board to reach the at least one heat radiator. The heat dissipation device of the multilayer circuit board can quickly and effectively conduct heat generated by the electronic chips on the multilayer circuit board, can achieve the heat dissipation, can avoid heat accumulation and can prolong the service life of the circuit board component.

Description

technical field [0001] The invention relates to the field of circuit board heat dissipation, in particular to a heat dissipation device for a multilayer circuit board. Background technique [0002] In electronic system products, generally known printed circuit boards are used to carry electronic components, usually using a flat substrate composed of glass fiber cloth or a soft substrate, and then printing a conductive layer on the substrate, or forming a circuit on the substrate After that, multiple circuit layers and insulation layers are laminated by gluing the work clothes, and processed to complete the production of multilayer printed circuit boards. As electronic products move towards the design concept of "thin, thin and small", printed circuit boards are also developing in the direction of small aperture, high density, multi-layer, and thin lines. Among them, multi-layer circuit board is a good solution to increase circuit density. [0003] However, the thermal cond...
