Abstract
The utility model discloses a kind of heat-conducting pad with metal level, including heat-conducting pad and metal foil, heat-conducting pad is coated on interior and heat-conducting pad outer surface and is fitted with metal foil inner surface installation by the metal foil, metal foil outer surface is pasted with conductive double sided adhesive tape, the upper strata mould release membrance being fitted on conductive double sided adhesive tape is provided with above metal foil, the lower floor's mould release membrance being fitted on conductive double sided adhesive tape is provided with below the metal foil.With heat-conducting pad be combined together metal foil by improvements over the prior art by the utility model, so that three kinds of realization conduction, heat conduction and the interface filling effect with certain compression ratio are acted on simultaneously, range of application is more extensively and flexible.
Description
Technical field
A kind of Copper Foil heat-conducting pad of the utility model.
Background technology
Heat-conducting pad is a kind of very outstanding thermal interfacial material, good heat conductivility, for filling design gap, row
Except air, outstanding contact heat conductien is realized.But under some special applications scenes, we not merely need heat-conducting pad material
With the outstanding capacity of heat transmission, while also needing to it has outstanding electric conductivity.Conventional mode, we can be toward pad product
The middle addition conductive filler such as filling component such as copper powder, silver powder, aluminium powder and zinc powder, obtains the relatively low conductive articles of specific insulation,
But at the same time the physical property such as product hardness in itself there occurs huge change.Heat conduction field is hard to heat-conducting pad product
The demand of degree is weighed with shore 00, and the pad product of conductive energy its hardness often reaches shore A ranks, together
When due to the limitation of packing material proportioning, have to make tendentious choice with conductive two aspect in heat conduction, so that pad
Flake products cannot be really achieved the perfect adaptation of heat conduction and conduction.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of while having conductive, heat conduction and with certain compression ratio
Interface filling effect the heat-conducting pad with metal level.
In order to solve the above-mentioned technical problem, the utility model takes following scheme：
A kind of heat-conducting pad with metal level, including heat-conducting pad, also including metal foil, the metal foil is by heat-conducting pad bag
Overlay on interior and heat-conducting pad outer surface to be fitted with metal foil inner surface installation, metal foil outer surface is pasted with conductive double sided adhesive tape,
The upper strata mould release membrance being fitted on conductive double sided adhesive tape is provided with above metal foil, is provided with below the metal foil and is fitted in conductive pair
Lower floor's mould release membrance on the glue of face.
The metal foil is Copper Foil or aluminium foil.
The thickness of the heat-conducting pad is 0.2-6.00mm.
12-100 microns of the metal foil.
The thickness of the conductive double sided adhesive tape is 5 microns, 10 microns or 15 microns.
The thickness of the upper strata mould release membrance and lower floor's mould release membrance is 50 microns, 75 microns or 100 microns.
With heat-conducting pad be combined together metal foil, and pass through by the utility model by improvements over the prior art
The restriction of ad-hoc location, heat-conducting pad is coated on completely using metal foil in.Have the advantages that：
1st, electronic product knot can be filled with using the thickness of itself as very outstanding thermal interfacial material, heat-conducting pad
Gap in structure design, excludes air and realizes outstanding contact heat conductien.
2nd, the purposes such as good ground connection and shielding are reached using the outstanding electric conductivity of Copper Foil or aluminium foil.
3rd, there is the characteristic of the elastic and certain moulding ability of adaptation using heat-conducting pad, extraordinary support can be played
With the effect of extruding contact, the conducting to electricity is realized, and serve good anti seismic efficiency.
4th, the material of the preferred flame retardant rating V-0 (UL94) of heat-conducting pad, whole product is without special flame retardant treatment.
Brief description of the drawings
Accompanying drawing 1 is the utility model axial section structural representation.
Specific embodiment
For the ease of the understanding of those skilled in the art, the utility model will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1, the utility model discloses a kind of heat-conducting pad with metal level, including heat-conducting pad 4, also wraps
Metal foil 3 is included, heat-conducting pad 4 is coated on interior and heat-conducting pad outer surface and is fitted with metal foil inner surface peace by the metal foil 3
Dress, the outer surface of metal foil 3 is pasted with conductive double sided adhesive tape 2, and the top of metal foil 3 is provided with the upper strata being fitted on conductive double sided adhesive tape 2
Mould release membrance 1, the lower section of the metal foil 3 is provided with the lower floor's mould release membrance 5 being fitted on conductive double sided adhesive tape 2.Metal foil is preferably Copper Foil
Or aluminium foil.
In specific making, first the conductive double sided adhesive tape in the outer surface attachment of metal foil, then will post conductive double sided adhesive tape
Metal foil heat-conducting pad outer surface is coated on by cladding process, heat-conducting pad and metal foil is brought into close contact installation, the gold
In completely be coated on heat-conducting pad by category paper tinsel.It is last to be obtained metal foil is teamed by upper strata mould release membrance and lower floor's mould release membrance again
Finished product.
For heat-conducting pad, the material of flame retardant rating V-0 (UL94) may be selected, whole product without special flame retardant treatment,
So that whole making more simplifies.
Additionally, in order that whole product is more frivolous, and meeting conductive radiator performance, the thickness of heat-conducting pad is 0.2-
6.00mm.12-100 microns of metal foil, can such as be chosen for 12 microns, 17 microns, 25 microns, 40 microns or 50 microns.It is conductive
The thickness of double faced adhesive tape is 5 microns, 10 microns or 15 microns.The thickness of upper strata mould release membrance and lower floor's mould release membrance is 50 microns, 75 micro-
Rice or 100 microns.
It should be noted that the above is not to restriction of the present utility model, wound of the present utility model is not being departed from
On the premise of making design, any obvious replacement is within protection domain of the present utility model.
