Abstract
The utility model is related to aluminium base design field, more particularly to a kind of bent aluminium base, including flexible PCB and aluminium sheet, the size of flexible PCB and aluminium sheet, shape all same, the side plate face of flexible PCB is fixed with component, another lateral plates and the plate face of aluminium sheet fit fixation, become into a bent shape by bending special plane after flexible PCB and aluminium sheet laminating, flexible PCB and aluminium sheet are superimposed together in the utility model and are used as aluminium base, wherein, aluminium sheet thermal diffusivity is preferable, the bending of flexible PCB is preferable, therefore the aluminium base that is overlapped into not only perfect heat-dissipating, when the aluminium base being overlapped into is bent, component, which is fixed on flexible PCB, just will not damage, also be not in leakage copper, short-circuit situations such as, the cost of flexible PCB and aluminium sheet is relatively low.
Description
Technical field
The utility model is related to aluminium base design field, more particularly to a kind of bent aluminium base.
Background technology
Aluminium base is a kind of metal-based copper-clad plate with good heat radiating function, is used frequently as LED lamp with wiring board,
Aluminium base is the most widely used one kind of metal substrate, with good thermal conductivity, electric insulating quality, to thermal expansion in circuit design
Dissipating has extremely effective processing, without radiator, with reduction product running temperature, improves product power density and reliable
Property, extend product service life, reduce small product size, reduction hardware and assembly cost, replace frangible ceramic substrate, obtain more
Good mechanical endurance.But when the moulding and matching requirements by structural member, it is necessary to bending be carried out to aluminium base, according to one
As mask-making technology flow, directly to monoblock aluminium base carry out bending will occur leakage copper, component damage, short circuit situations such as；
And if carrying out bending using the aluminium base of special material, Master Cost is too high；If being spliced into two pieces of single aluminium bases,
The need for moulding and statutory standard can not be met again.
Utility model content
The purpose of this utility model be overcome prior art exist defect there is provided a kind of bent aluminium base, cost
It is relatively low and component will not be damaged.
The utility model solves the technical scheme that its technical problem used：A kind of bent aluminium base, including it is soft
Size, the shape all same of property circuit board and aluminium sheet, flexible PCB and aluminium sheet, the side plate face of flexible PCB are fixed with member
The plate face of device, another lateral plates and aluminium sheet fits fixation, is become after flexible PCB and aluminium sheet laminating by bending special plane
Bending.
Beneficial effect：Flexible PCB and aluminium sheet are superimposed together as aluminium base in the utility model, wherein, aluminium sheet
Preferably, preferably, therefore the aluminium base being overlapped into not only perfect heat-dissipating will be overlapped into thermal diffusivity for the bending of flexible PCB
Aluminium base when being bent, component, which is fixed on flexible PCB, just will not damage, and also be not in the feelings such as leakage copper, short circuit
The cost of condition, flexible PCB and aluminium sheet is relatively low.
Brief description of the drawings
Fig. 1 is stereogram of the present utility model.
In figure：10- flexible PCBs；20- aluminium sheets；30- components.
Embodiment
With reference to Fig. 1, the utility model will be further described.
A kind of bent aluminium base, including flexible PCB 10 and aluminium sheet 20, flexible PCB 10 and aluminium sheet 20 it is big
Small, shape all same, the side plate face of flexible PCB 10 is fixed with the plate face phase of component 30, another lateral plates and aluminium sheet 20
Laminating is fixed, and is become into a bent shape by bending special plane after flexible PCB 10 and the laminating of aluminium sheet 20.
In the utility model, flexible PCB 10 and aluminium sheet 20 are superimposed together as aluminium base, wherein, flexible circuit
Plate 10 is that be made by base material of polyimides or polyester film a kind of has height reliability, excellent pliable printed circuit
Plate, and good, Distribution density is high, lightweight with bending property, thickness of thin the features such as, in addition, the thermal diffusivity of aluminium sheet 20 is preferably, therefore folded
The aluminium base of synthesis not only perfect heat-dissipating, and when the aluminium base being overlapped into is bent, because of flexible PCB 10
Body has good bending, and component 30 is fixed on flexible PCB 10 and just will not damaged, and is also not in leakage copper, short circuit
Situations such as, the service life of component 30 and whole aluminium base is longer, in addition, the cost of flexible PCB 10 and aluminium sheet 20 is equal
Relatively low, so the cost of whole aluminium base is relatively low, and the utility model is set with more ripe Mechanized Processing and detection
Standby production, improves the efficiency of production, the quality of product is also guaranteed.
It is used as further preferred scheme：Between the flexible PCB 10 and aluminium sheet 20 via adhered by double sided plaster together
And fixed by crimp connection fixture pressurization, more convenient using adhered by double sided plaster, the use of crimp connection fixture ensures flexible PCB 10
Together with the good bond of aluminium sheet 20.
Further, the component 30 is fixed on flexible PCB 10 by tin cream.
It should be appreciated that specific embodiment described above is only used for explaining the utility model, it is not used to limit this reality
With new.The obvious changes or variations extended out by spirit of the present utility model is still in protection of the present utility model
Among scope.
