Description

Technical Field

[0001] The utility model relates to the technical field of substrates, in particular to a multi-layer composite substrate. Background Art

[0002] Substrate is the basic material for manufacturing PCB. Generally speaking, substrate is copper-clad laminate. Single-sided and double-sided printed circuit boards are made of substrate materials during manufacturing. Printed circuit boards related to electronic products integrate the conductive functional layer with the substrate.

[0003] In the prior art, when a substrate is actually used after the conductive functional layer is integrated, since the substrate does not have a dual-channel multi-layer composite structure and a substrate edge surrounding press-fit assembly structure, the substrate cannot be used for efficient heat dissipation and the substrate edge cannot be protected from damage, thereby affecting the service life of the circuit board.

[0004] Therefore, it is necessary to design a multi-layer composite substrate to solve the above-mentioned problems. Summary of the invention

[0005] The purpose of the utility model is to provide a multi-layer composite substrate to improve the substrate with a dual-channel multi-layer composite structure and a substrate edge surrounding press-fit assembly structure, to ensure efficient heat dissipation of the substrate and protection of the substrate edge from damage, thereby solving the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A multi-layer composite substrate comprises a composite substrate body, both sides of which are sleeved with fixed frames, front and rear ends of which are sleeved with fixed end covers, the composite substrate body comprises a centrally arranged reinforcing plate core, the top of the reinforcing plate core is fixedly connected with a first insulating heat dissipation mesh layer, the top of the first insulating heat dissipation mesh layer is fixedly connected with a first substrate layer, the bottom of the reinforcing plate core is fixedly connected with a second insulating heat dissipation mesh layer, and the bottom of the second insulating heat dissipation mesh layer is fixedly connected with a second substrate layer.

[0008] As a preferred solution of the utility model, the reinforcing plate core is composed of a resin layer with built-in glass fiber cloth.

[0009] As a preferred solution of the utility model, the fixed frame is a U-shaped frame structure, and there are two fixed frames in total. The outer surfaces of the two fixed frames are provided with two first heat dissipation grooves on one side corresponding to the first insulating heat dissipation mesh layer and the second insulating heat dissipation mesh layer.

[0010] As a preferred solution of the utility model, there are two fixed end covers in total, and two second heat dissipation grooves are provided on one side of the outer surface of the two fixed end covers corresponding to the first insulating heat dissipation mesh layer and the second insulating heat dissipation mesh layer.

[0011] As a preferred solution of the utility model, the outer edges of the bottom of the second substrate layer and the top of the first substrate layer are both provided with an adhesive layer fixedly connecting the fixed frame and the fixed end cover.

[0012] As a preferred solution of the present invention, a protective coating is coated on the bottom of the second substrate layer and the center of the top of the first substrate layer.

[0013] Beneficial effect: In view of the problem in the prior art that the substrate does not have a dual-channel multi-layer composite structure and a substrate edge surrounding and pressing assembly structure, so that the substrate cannot be used for efficient heat dissipation and the substrate edge cannot be protected from damage, in the utility model, a composite substrate body is formed by arranging a reinforced core, a first insulating heat dissipation mesh layer, a first substrate layer, a second insulating heat dissipation mesh layer, and a second substrate layer, and a fixed frame with a first heat dissipation groove and a fixed end cover with a second heat dissipation groove are arranged around the composite substrate body, so that the entire substrate has a dual-channel multi-layer composite structure and a substrate edge surrounding and pressing assembly structure, thereby facilitating the efficient heat dissipation of the substrate and the protection of the substrate edge from damage.
