Abstract
The utility model discloses a circuit board, comprising a substrate, a pad, fixed orifices and components, wherein the fixed orifices are installed in four corners of the substrate, the periphery of each fixed orifice is provided with a fixed ring, the components are welded on the pad, and a heat conducting silica gel is coated on one surface of the substrate and is smeared on the back surface of a corresponding component. The utility model has the following beneficial effects: 1, through installation of the fixed rings, the overall structure of the substrate is firmer, and the fixed rings are made of aluminum sheet, posing no influence on integral quality of the substrate; 2, the service life of the components is substantially prolonged through coating of a layer of the heat conducting silica gel on the back surfaces of the components installed on the substrate; and 3, the circuit board has the advantages of a simple structure, convenient installation and low cost.
Description
Technical field
The utility model relates to a kind of circuit board.
Background technology
At present, the application of circuit board in real life is very extensive, especially in electronic product, indispensable, existing circuit board generally is to be provided with a plurality of fixing holes, because fixing hole is direct perforate, is easy to make circuit board separately, insecure, next because other components and parts such as chip produce very big heat, causes significantly reduce the useful life of components and parts in existing circuit board, needs often maintenance, inconvenience very, the cost height.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of simple in structure, and is easy for installation, and fixed, the circuit board of good heat dissipation effect.
The utility model is achieved through the following technical solutions:
A kind of circuit board of the present utility model, comprise substrate, pad, fixing hole and components and parts, described fixing hole is installed in four jiaos of places of substrate, described fixing hole outer ring is equipped with retainer ring, described components and parts are welded on the pad, be coated with heat conductive silica gel on the described substrate one side, and heat conductive silica gel spreads upon the corresponding components and parts back side.
As optimized technical scheme, described retainer ring is the aluminium skin.
As optimized technical scheme, described fixing hole is counterbore.
As optimized technical scheme, described substrate and heat conductive silica gel are combined into one by adhesive.
Circuit board beneficial effect of the present utility model is: 1, by installing and fixing ring, make the substrate overall structure more firm, and retainer ring is the aluminium skin, and influenced to basic total quality portion; 2, be coated with one deck heat conductive silica gel by the back side that components and parts are installed at substrate, make big leap aheads in useful life of components and parts; 3, simple in structure, easy for installation, cost is low.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.
Fig. 1 is the front view of circuit board of the present utility model;
Fig. 2 is the upward view of circuit board of the present utility model.
Embodiment
Consult the described a kind of circuit board of the present utility model of Fig. 1 and Fig. 2, comprise substrate 1, pad 2, fixing hole 3 and components and parts 4, described fixing hole 3 is installed in 1 four jiaos of places of substrate, described fixing hole 3 outer rings are equipped with retainer ring 5, described components and parts 4 are welded on the pad 2, be coated with heat conductive silica gel 6 on described substrate 1 one side, and heat conductive silica gel 6 spreads upon corresponding components and parts 4 back sides.
Wherein, described retainer ring 5 is the aluminium skin.
Described fixing hole 3 is counterbore.
Described substrate 1 and heat conductive silica gel 6 are combined into one by adhesive.
Circuit board beneficial effect of the present utility model is: 1, by installing and fixing ring, make the substrate overall structure more firm, and retainer ring is the aluminium skin, and influenced to basic total quality portion; 2, be coated with one deck heat conductive silica gel by the back side that components and parts are installed at substrate, make big leap aheads in useful life of components and parts; 3, simple in structure, easy for installation, cost is low.
The above only is embodiment of the present utility model, but protection range of the present utility model is not limited thereto, and any variation or replacement of expecting without creative work all should be encompassed within the protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range that claims were limited.
