Technical field
The present invention relates to anisotropic conductive connects with film and spool body.
Background technology
All the time; As to relatively to circuit substrate or electronic unit heat, pressurize; And optionally make the connection material that is electrically connected between electrode or the terminal of compression aspect; Use anisotropic conductive film (below; Be called ACF) or circuit connection material such as the bonding film of insulativity (below, be called NCF).For ACF; Connecting printed circuit substrate, LCD with substrates such as glass substrate, flexible printing substrates, or when semiconductor element such as IC, LSI or package etc., be configured in relative to electrode between; And, optionally carry out between connection electrode or the terminal through heating and pressurizing.That is to say, ACF and NCF shown have simultaneously relatively to electrode or the electroconductibility between the terminal, and the anisotropic conductive of adjacent electrode or the insulativity between the terminal connects.Therefore, these bonding films have electrical connection and the function of this two aspect of mechanical connection (bonding) between circuit substrate or electronic unit.
Representational ACF and NCF preferably use caking agent compositions such as epoxy resin caking agent or acrylic acid series caking agent.For example, ACF is that the electroconductive particle that will be cooperated as required is dispersed in the above-mentioned caking agent composition and forms.These bonding films carry out commercialization with the belt-like form that is layered on the supporting films such as PET (polyethylene terephthalate) film.In addition, for the surface of protecting these bonding films makes its not dust in the ingress of air etc., the further situation (for example, referring to patent documentation 1) of stacked guard film is arranged also on the interarea of bonding film and supporting film opposition side.
Among Fig. 4, the anisotropic conductive that the three-decker of above-mentioned range upon range of supporting film, bonding film and protective membrane is shown is connected the example in the past with film.Fig. 4 representes that anisotropic conductive connected the end with the film length direction in the past.Anisotropic conductive connects with film 40, has the structure that bonding films 42 such as having stacked gradually supporting film 41, ACF and protective membrane 43 form.In the past anisotropic conductive connects with film 40, can pass through with above-mentioned each film 41,42 and 43 range upon range of after, obtain with respect to stacked direction perpendicular cuts to specified length.Therefore, this anisotropic conductive connects end face 4a and the stack direction quadrature with film 40 length directions, and each film 41,42 and 43 end face are evened up mutually.
Use the anisotropic conductive of this three-decker to connect connection, usually, carry out as follows with the circuit substrate of film 40 or the electrode in the electronic unit etc.At first, protective membrane 43 is connected to peel off with film 40 from anisotropic conductive remove.Then, the interarea that makes the bonding film 42 that exposes and circuit substrate etc. contacts by the sticky object surface and interim the pressure glued.Then, peel off and remove supporting film 41.Then, another interarea that makes the bonding film 42 that exposes contact by the sticky object surface with other, and pressurization heating on one side (the formal pressure glued) on its stacked direction on one side, accomplishes the connection of electrode that this circuit substrate etc. had etc. thus.Peeling off of protective membrane 43 removed, and for example, can carry out through waiting between bonding film 42 and protective membrane 43, to peel off with finger.

Summary of the invention
Yet in recent years, along with the miniaturization of various e-machines, circuit substrate that is had in this e-machine or electronic unit are also in miniaturization step by step.Therefore, require bonding films such as ACF in its filmization, make further that film is wide to narrow down.
Yet anisotropic conductive in the past shown in Figure 4 connects with film 40, and along with its filmization and film width narrow, selective detachment is removed protective membrane 43 and become difficult gradually.That is to say that because this anisotropic conductive connects with film 40, its end face 4a is above-mentioned form, therefore, when making that thickness attenuation or film are wide to narrow down, use finger to wait only between protective membrane 43 and bonding film 42, to peel off to become difficult.
In addition, it is also conceivable that adhesive tape joining on the interarea that protective membrane 43 and supporting film 41 expose, and pull each other, peel off the method for removing protective membrane 43 thus.When this method of use was peeled off, the stripping strength between supporting film 41 and the bonding film 42 should be than high certain degree of the stripping strength between protective membrane 43 and the bonding film 42.Yet this stripping strength also exists with ... the constituent material of bonding film 42, and this constituent material determines according to the purposes of bonding film 42.Therefore, also have the situation of above-mentioned stripping strength required in the time of can't obtaining removing protective membrane 43 through the method selective detachment that uses splicing tape.
Therefore; The present invention In view of the foregoing carries out; And purpose is to provide a kind of anisotropic conductive to connect and use film, and it can fully guarantee optionally only to peel off one that removes in the film of clamping bonding film, and provides and have the spool body of this anisotropic conductive connection with film.
To achieve these goals; The present invention provides a kind of anisotropic conductive to connect and uses film; It is to have the zonal anisotropy who stacks gradually the duplexer that the 1st film, bonding film and the 2nd film form to conduct electricity to be connected and use film; Wherein, Bonding film protrudes in reference plane, said reference plane for the cross section of the interarea of end face and the bonding film of the length direction that in face, has the 2nd film and with the orthogonal reference plane of interarea of bonding film.
Anisotropic conductive in the past connects under the situation with film 40, does not contact with supporting film 41 with bonding film 42, and only pinches protective membrane 43, comes down to impossible.Therefore, to remove the protective membrane 43 that this anisotropic conductive connects with film 40 be very difficult to selective detachment.
On the other hand, anisotropic conductive of the present invention connects uses film, because its bonding film is more outstanding than said reference face, therefore can use finger, does not pinch the 2nd film ground and at least only pinches bonding film.Then, if the bonding film that will pinch and according to circumstances except bonding film, also have the 1st film is bent to the 1st film side of stacked direction,, and cause the 2nd film and bonding film on the direction that pulls mutually, to apply power then because the elasticity of flexure function of the 2nd film.Thus, the 2nd film is peeled off from the end face side of its length direction.Then, pinch the released part of the 2nd film again, perhaps, hold the splicing tape that sticks on the 2nd film and the 1st film, on the direction that is separated from each other, pull bonding film and the 2nd film, then can fully guarantee optionally only to peel off to remove the 2nd film.
Using film when anisotropic conductive of the present invention connects, further have when being used to indicate the indicating member of the 2nd film end face, is preferred.Thus, use the film miniaturization even anisotropic conductive connects, therefore the end face of Visual Confirmation the 2nd film at an easy rate, can not contact with the 2nd film, and only pinch bonding film etc. more easily yet.The result can more guarantee and peel off easily and remove the 2nd film.
In addition, the present invention provides a kind of spool body, and it has the volume core, is connected and uses film with above-mentioned anisotropic conductive on being wound on this volume core.The anisotropic conductive of from this spool body, pulling out connects uses film, owing to have above-mentioned formation, therefore can fully guarantee optionally only to peel off and remove the 2nd film.
According to the present invention, can provide a kind of anisotropic conductive to connect and use film, it can fully guarantee optionally only to peel off one that removes in the film of clamping bonding film.

Embodiment
Below, as required,, preferred implementation of the present invention is elaborated with reference to accompanying drawing.In addition, in the accompanying drawing, identical element gives identical symbol, and omits the multiple explanation.And, wait the position relation up and down, do not have to specify, based on position shown in the drawings relation.In addition, the dimension scale of accompanying drawing is not limited to illustrated ratio.
Fig. 1 is that the zonal anisotropy that schematically illustrates preferred the 1st embodiment of the present invention is conducted electricity and connected the sectional view with film length direction end.The anisotropic conductive of this embodiment connects with film 10, has the supporting film 11 that stacks gradually as the 1st film, bonding film 12, as the duplexer that forms 15 of the protective membrane 13 of the 2nd film.In addition, this anisotropic conductive connects with film 10, on the interarea of protective membrane 13 and bonding film 12 opposition sides, has the indicating member 18 of the end face 13a that is used to indicate protective membrane 13.
The width that anisotropic conductive connects with film 10 is preferably 0.3～320mm, and 0.5～10mm more preferably.Thus, according to the present invention, can more effectively play and optionally only to peel off the advantageous effects of removing protective membrane.
In the 1st embodiment, supporting film 11, bonding film 12 and protective membrane 13 are parallel to the face of the stacked direction S of duplexer 15 at end face 11a, 12a and the 13a of length direction L.In these end faces, the end face 11a of supporting film 11 and the end face 12a of bonding film 12 even up mutually.In addition, supporting film 11 and bonding film 12 protrude in the end face 13a of protective membrane 13, and consequently, the part of the interarea 12b of bonding film 12 is exposed.
The end face 13a of protective membrane 13 and the reference plane 16 among the present invention are evened up, said reference plane 16, promptly in face, have protective membrane end face 13a and bonding film 12 interarea 12b cross section X and with orthogonal of the interarea 12b of bonding film 12.In other words, bonding film 12 protrudes in reference plane 16.
The anisotropic conductive of this embodiment connects with film 10, because bonding film 12 protrudes in reference plane 16, therefore can use finger to wait and not pinch protective membrane 13, and optionally only pinch supporting film 11 and bonding film 12.Then, if these films 11 and 12 that will pinch are bent to supporting film 11 sides of the stacked direction S of duplexer 15,, and cause film 11 on the direction of mutual pulling, to apply power with protective membrane 13 with 12 then because the elasticity of flexure effect of protective membrane 13.Thus, protective membrane 13 is peeled off from end face 13a side.Then, the stripping portion that pinches protective membrane 13 is again graded, and on direction disconnected from each other stretched film 11 and 12 and protective membrane 13, then can fully guarantee optionally only to peel off to remove protective membrane 13.
The interarea 12b of bonding film 12 preferably exposes the degree that optionally pinches bonding film 12 and supporting film 11 to the enough fingers of ability.Specifically, preferably expose to the distance D between the end face 12a of the end face 13a of protective membrane 13 and bonding film 12 be 1～100mm, 5～80mm more preferably, and further be preferably 10～50mm.If this distance D is less than 1mm, the then selective supporting film 11 that pinches becomes difficult tendency with bonding film 12.On the other hand, if distance D surpasses 100mm, remove easy degree though then can change peeling off of protective membrane 13 hardly, the exposed portions serve that has bonding film 12 surfaces that will protect becomes many, and the loss of bonding film 12 becomes big tendency.
Supporting film 11 can be an individual layer, also can be range upon range of structure more than 2 layers.Supporting film 11 preferably has more than one the film that is selected from polyethylene terephthalate (PET) film, orientation polypropylene (OPP) film, Vilaterm (PE) film and polyimide film.Wherein, consider, be preferably PET film and/or OPP film from the viewpoint that can improve thermotolerance and reduce cost, and PET film more preferably.
In addition, supporting film 11 can use demoulding treatment agent that the interarea that is provided with bonding film 12 1 sides is handled as required, also can implement roughened to this interarea.As demoulding treatment agent, for example, can enumerate organosilicon, silicone alkyd, alkyd amino, alkyl alkyd and trimeric cyanamide.In addition, supporting film 11 also can use its interareas of coating such as polymkeric substance.These processing can be used a kind separately, also can will combine more than 2 kinds.
Bonding film 12 can be through supporting coating adhesive composition and dry obtaining on the base material.This bonding film 12 also can be through being formed on the supporting film 11 at coating adhesive composition on the interarea of supporting film 11 and drying.Perhaps, bonding film 12 can also obtain film through coating adhesive composition and drying on the support base material different with supporting film 11, peels off this film from this support base material again, is laminated to then on the interarea of supporting film 11 and is formed on the supporting film 11.
Bonding film 12 can be an individual layer, also can have the structure more than 2 layers range upon range of.In this case, bonding film 12 can through will be in the above described manner formed bonding film as stratum basale, further form bonding film thereon and obtain.Perhaps, it can also make as stated in formed bonding film on the supporting film 11 and the mutual subtend of bonding film that on protective membrane 13, likewise forms and carry out pressing and obtain.
As the adhesive composite of bonding film 12 raw materials, be preferably and carry out the material that anisotropic conductive connects.Therefore, this adhesive composite can contain thermoplastic resin, free-radical polymerised compound and radical polymerization initiator.Perhaps, this adhesive composite can also contain thermoplastic resin, thermosetting resin and potentiality solidifying agent.Contained each composition in the above-mentioned adhesive composite is so long as contained material gets final product in the so-called in the past anisotropic conductive caking agent.
Above-mentioned adhesive composite, can contain with in the past anisotropic conductive caking agent in the contained identical electroconductive particle of electroconductive particle, can not contain yet.By the formed bonding film 12 of the adhesive composite that contains electroconductive particle, through electroconductive particle optionally connect relatively to electrode and/or terminal between, and will contain the substrate of these electrodes and/or terminal simultaneously or install bonding.By the formed bonding film 12 of the adhesive composite that does not contain electroconductive particle, through make relatively to electrode and/or terminal directly contact, will contain the substrate of these electrodes and/or terminal or install bondingly, optionally connect these electrodes and/or terminal thus.
Further, this adhesive composite, except above-mentioned each the composition, can also contain in the past contained composition in the anisotropic conductive caking agent.
When bonding film 12 had had the structure more than 2 layers range upon range of, each layer can be identical composition each other, also can be different compositions.That is to say, as the composition of the adhesive composite of each layer raw material, can be identical each other, also can be different, and can have the layer that contains electroconductive particle and this two kinds of layers of layer that do not contain electroconductive particle.For example, when bonding film 12 had had 2 layers structure range upon range of, the layer of supporting film 11 1 sides can be the layer that does not contain electroconductive particle, protective membrane 13 1 sides layer can be the layer that contains electroconductive particle.
As the method that protective membrane 13 is configured on the bonding film 12, can enumerate the further method of stacked guard film 13 on bonding film 12 surfaces such as laminating machine of using.Perhaps, can also make as stated in formed bonding film on the supporting film 11 and the same manner forms on protective membrane 13 the mutual subtend of bonding film and carry out pressing and obtain.
As making supporting film 11 and bonding film 12 protrude in the method for reference plane 16, can be set forth in the duplexer of supported film 11, bonding film 12 and protective membrane 13 after, the method for the end of tripping protection film 13 only optionally.Perhaps, can be set forth in the duplexer that forms supporting film 11 and bonding film 12 after, the mode configuration protection film 13 by the part of the interarea 12b of bonding film 12 is exposed in advance carries out range upon range of method again.
In addition, the difference of the stripping strength between stripping strength between supporting film 11 and the bonding film 12 and protective membrane 13 and the bonding film 12 is preferably 0.001～10N/m.Anisotropic conductive connects with film 10, removes protective membrane 13 in order optionally to peel off, and the stripping strength between preferred supporting film 11 and the bonding film 12 is stronger than the stripping strength between protective membrane 13 and the bonding film.On the other hand, consider at circuit substrate etc. and peel off behind the bonding film 12 of pressing on by sticky object when removing supporting film 11, preferably stronger than the stripping strength between supporting film 11 and the bonding film 12 by the stripping strength between sticky object and the bonding film 12.When these situation are taken all factors into consideration, preferably be in the stripping strength difference in the above-mentioned numerical range.
In in the past anisotropic conductive connects with film, when the difference of stripping strength is in this numerical range, has and be difficult to optionally only peel off the tendency of removing protective membrane.Yet,,, also can fully guarantee optionally only to peel off to remove protective membrane 13 even this anisotropic conductive connects with film 10 according to the present invention.
In addition, the stripping strength among the present invention uses mobilometer to measure.
The difference of above-mentioned stripping strength can be adjusted stripping strength and/or the stripping strength between protective membrane 13 and the bonding film 12 between supporting film 11 and the bonding film 12 through mode as described below, and drop in the above-mentioned numerical range.Specifically; In order to improve stripping strength; As long as reduce content as the resin (thermoplastic resin) in the adhesive composite of bonding film 12 raw materials; Perhaps reduce the glass transformation temperature (Tg) of this resin; Perhaps improve the content of free-radical polymerised compound or thermosetting resin, perhaps roughened is carried out on the surface of supporting film 11 and protective membrane 13 and get final product.Perhaps, in order to improve stripping strength, when bonding film 12 contained the solids of electroconductive particle or insulativity, the content that reduces these particles got final product.Perhaps, in order to reduce stripping strength, use demoulding treatment agent that supporting film 11 or protective membrane 13 are carried out surface treatment, or the thickness that reduces these films get final product.
The thickness of supporting film 11, bonding film 12 and protective membrane 13 is adjusted according to its purposes etc. and to be got final product, and not special restriction.But as stated, preferably with the thickness of supporting film 11 and protective membrane 13, the elongation difference that is adjusted to per unit width diminishes, and suitable difference with stripping strength is adjusted to and falls in the above-mentioned numerical range.
Indicating member 18 is used to indicate the end face 13a of protective membrane 13., be difficult to when being transparent or semitransparent at protective membrane 13 especially through its end face of Visual Confirmation 13a.Therefore, if can confirm the position of end face 13a, then can more easily carry out peeling off of protective membrane 13 and remove processing through indicating member 18.This indicating member 18 can be confirmed to get final product through visual, for example is the strip-shaped parts of black, and preferred so that the axle mode parallel with the end face 13a of protective membrane 13 of its length direction is arranged on shown position with it.
The anisotropic conductive of this embodiment connects with film 10, is wound on core (not shown) and goes up the formation spool body.Constitute spool body thus, improved anisotropic conductive and connected operability with film 10.
Fig. 2 is that the zonal anisotropy that schematically illustrates preferred the 2nd embodiment of the present invention is conducted electricity and connected the sectional view with film length direction end.The anisotropic conductive of this embodiment connects with film 20, has to stack gradually the duplexer 25 that supporting film 21, bonding film 22 and protective membrane 23 form.
In the 2nd embodiment, end face 21a, 22a and the 23a of the length direction L of supporting film 21, bonding film 22 and protective membrane 23, for the parallel face of duplexer 25 stacked direction S.Supporting film 11 protrudes in the end face 22a of bonding film 22, and bonding film 22 protrudes in the end face 23a of protective membrane 23.Therefore, the part of the interarea 22b of the interarea 21b of supporting film 21 and bonding film 22 is exposed.
