Description
Technical field
The utility model is related to FPC field, and in particular to a kind of high efficiency and heat radiation FPC.
Background technology
FPC is subject to extensive use due to its flexible, its small volume, can bend repeatedly such that it is able to
It is applied on numerous electronic products such as mobile phone, camera, computer.With the integrated level more and more higher of FPC, electronics is produced
The performance of product is more and more stronger, but integrated excessive original paper causes heat to be collected on FPC, if can not be timely
Radiating, causes the service life of FPC to reduce.
Utility model content
Utility model purpose：The utility model is intended to overcome the defect of prior art, there is provided a kind of high efficiency and heat radiation flexible wires
Road plate.
Technical scheme：A kind of FPC, from top to bottom successively include the first cover layer, the first circuit layer, basic unit,
Second circuit layer and the second cover layer, the upper surface of the basic unit has multiple first blind holes, the following table mask of the basic unit
There are multiple second blind holes, the basic unit also has hot channel, and the top surface of the hot channel has multiple first grooves, described
The bottom surface of hot channel has multiple second grooves, and heat conductive silica gel is full of in first blind hole and the second blind hole.
Further, first groove and the second groove are hemispherical groove.
Further, first blind hole and the second blind hole are blind cylindrical hole.
Further, first circuit layer and second circuit layer are Copper Foil.
Further, the multiple first blind hole includes ranked first blind hole and the blind hole of multiple row first more；The multiple second
Blind hole includes ranked second blind hole and the blind hole of multiple row second more.
Further, hot channel has many, and parallel to each other.
Beneficial effect：FPC good heat dissipation effect of the present utility model, coordinates blowing apparatus, radiating effect to add all the more
By force.
Brief description of the drawings
Fig. 1 is FPC schematic diagram.
Specific embodiment
Reference：1 first cover layer；2 first circuit layers；3 basic units；4 second circuits layer；5 second cover layers；
3.1 first blind holes；3.2 second blind holes；3.3 hot channels；3.3.1 the first groove；3.3.2 the second groove.
A kind of FPC, includes the first cover layer 1, the first circuit layer 2, the electricity of basic unit 3, second successively from top to bottom
The cover layer 5 of road floor 4 and second, the upper surface of the basic unit 3 has multiple first blind holes 3.1, the following table mask of the basic unit 3
There are multiple second blind holes 3.2, the basic unit 3 also has a hot channel 3.3, the top surface of the hot channel 3.3 has multiple the
One groove 3.3.1, the bottom surface of the hot channel 3.3 has multiple second groove 3.3.2, first blind hole 3.1 and second
Heat conductive silica gel is full of in blind hole 3.2.The first groove 3.3.1 and the second groove 3.3.2 are hemispherical groove.Described first
Blind hole and the second blind hole are blind cylindrical hole.First circuit layer and second circuit layer are Copper Foil.The multiple first
Blind hole includes ranked first blind hole and the blind hole of multiple row first more；The multiple second blind hole includes ranked second blind hole and multiple row second more
Blind hole.Hot channel has many, and parallel to each other.
First blind hole and the second blind hole in array-like arrangement, coordinate heat conductive silica gel, so that more by the heat of circuit layer
Amount is transferred in hot channel, has groove in hot channel, and so as to increase area of dissipation, and hot channel can be with external
Blowing device, so as to accelerate the air flow in pipeline, so as to accelerate to set groove in radiating, hot channel, and is not provided with convex
Rise, both increased area of dissipation, the circulation of radiation air will not be hindered again.
Although the utility model is illustrated and described with regard to preferred embodiment, those skilled in the art should manage
Solution, without departing from claim limited range of the present utility model, the utility model can be carried out various change and
Modification.
