Abstract
The invention discloses a flexible circuit board preventing elements from being overheated. The flexible circuit board preventing the elements from being overheated comprises a top insulating layer and a circuit layer, wherein the circuit layer is arranged below the top insulating layer; a heat dissipation assembly is arranged in the top insulating layer in the length direction and comprises a plurality of ventilating pipes which are arranged at intervals; the elements which are connected with the circuit layer are arranged on the top insulating layer; connecting holes are respectively formed below the elements; the connecting holes downwards extend from spaces among the adjacent ventilating pipes; and a bottom insulating layer is arranged below the circuit layer. By the mode, the ventilating pipes of the flexible circuit board preventing the elements from being overheated can be externally connected with ventilating equipment to conduct heat of the top insulating layer and cool down the top insulating layer, so that heat of the elements and heat of the circuit layer are taken away, the problem of local overheating is avoided, the elements are not directly blown, damage of the elements is reduced, and the service lives of the elements are prolonged.
Description
Technical field
The present invention relates to field of circuit boards, particularly relate to a kind of FPC avoiding element over-temperature.
Background technology
Along with the progress of production technology, the volume controlling casing of part numerical control device is more and more less, just towards lightening development.Due to reduced space, installing space is limited, generally uses FPC to carry out the hardboard that Substitute For Partial is traditional in control cabinet body.
FPC space availability ratio is high, flexible arrangement, and the control casing being suitable for narrow space uses, but due to limited space, the heat that element produces is assembled and is difficult to dispel the heat, and easily causes hot-spot and the problem damaged, needs improvement.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of FPC avoiding element over-temperature, the heat radiation at reinforcing element, it is to avoid the problem that local stability is too high.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of FPC avoiding element over-temperature, including: top layer and line layer, described line layer is arranged on the lower section of top layer, described top layer is provided with radiating subassembly along its length, described radiating subassembly includes several spaced ventilation duct, the element being connected with line layer it is provided with in described top layer, described element be respectively arranged below connecting hole, described connecting hole downwardly extends between adjacent ventilation duct, the lower section of described line layer is provided with bottom insulation layer.
In a preferred embodiment of the present invention, described ventilation duct is the copper pipe of hollow.
In a preferred embodiment of the present invention, described top layer and bottom insulation layer are respectively polyimides soft board.
In a preferred embodiment of the present invention, it is provided with the first tack coat between described top layer and line layer and is connected.
In a preferred embodiment of the present invention, it is provided with the second tack coat between described bottom insulation layer and line layer and is connected.
The invention has the beneficial effects as follows: a kind of FPC avoiding element over-temperature that the present invention points out, ventilation duct can carry out heat conduction and cooling with external ventilation equipment to top layer, thus taken away the heat of element and line layer, the problem avoiding hot-spot, and directly element is not blown, decrease the damage of element, extend the service life of element.
Accompanying drawing explanation
For the technical scheme being illustrated more clearly that in the embodiment of the present invention, in describing embodiment below, the required accompanying drawing used is briefly described, apparently, accompanying drawing in describing below is only some embodiments of the present invention, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of a kind of FPC one preferred embodiment avoiding element over-temperature of the present invention.
Detailed description of the invention
Technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
Referring to Fig. 1, the embodiment of the present invention includes:
A kind of FPC avoiding element over-temperature, including: top layer 2 and line layer 5, described line layer 5 is arranged on the lower section of top layer 2, described top layer 2 is provided with radiating subassembly 3 along its length, described radiating subassembly 3 includes several spaced ventilation duct, ventilation duct can carry out heat conduction and cooling with external ventilation equipment to top layer 2, thus taken away element 1 and the heat of line layer 5, the problem avoiding hot-spot, and directly element 1 is not blown, facilitate top layer 2 and the sealing and dustproof of element 1, promote safety in utilization and stability.
The element 1 being connected with line layer 5 it is provided with in described top layer 2, described element 1 be respectively arranged below connecting hole 21, described connecting hole 21 downwardly extends between adjacent ventilation duct, leaves the gap of connecting hole 21 test between adjacent ventilation duct, facilitates the installation of element 1.
The lower section of described line layer 5 is provided with bottom insulation layer 7, described top layer 2 and bottom insulation layer 7 and is respectively polyimides soft board, and the insulation effect of polyimides soft board is good, strengthens the protection to line layer 5, and flexible, facilitates the bending of wiring board to construct.
Described ventilation duct is the copper pipe of hollow, and the thermal conductivity of copper pipe is good, and flexible, can bend to arc, and the convenience of bending construction is good.
It is provided with the first tack coat 4 between described top layer 2 and line layer 5 to be connected, is provided with the second tack coat 6 between described bottom insulation layer 7 and line layer 5 and is connected.Line layer 5 both can be positioned by the first tack coat 4 and the second tack coat 6, again can connection between reinforced top insulating barrier 2 and bottom insulation layer 7, structure is more firm.
In sum, a kind of FPC avoiding element over-temperature that the present invention points out, sound construction, flexible, convenient bending construction, and also the performance of ventilation and heat dispersion of top layer 2 is good, improves the stability in use of element.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the invention content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical field, the most in like manner it is included in the scope of patent protection of the present invention.
