[embodiment]
Fig. 1 to Fig. 4 discloses the principle that making method for electric connector of the present invention utilizes.
Please refer to Fig. 2 (a), shown in (b), because CNT (carbon nano-tube) can be subject to galvanic couple polarization in various degree under the impact of additional AC field, this phenomenon is called as dielectric property.And CNT (carbon nano-tube) is after receiving galvanic couple polarization, just can by Jie's driven by power, the CNT (carbon nano-tube) that galvanic couple is polarized carries out swimming in dispersion liquid, more can carry out assembling and arranging along the direction of extra electric field.Therefore we claim this phenomenon to be dielectrophoresis.
Fig. 2 (a) discloses CNT (carbon nano-tube) by galvanic couple; Fig. 2 (b) then discloses by the CNT (carbon nano-tube) of galvanic couple under the effect of electric field, just arranges along the direction of electric field.
Fig. 3 A is then for the present invention utilizes " vertical type dielectrophoresis " to reach the integrated method becoming the integrated bundle of nanometer with cluster nano carbon pipe.So-called " vertical type dielectrophoresis " refers to be different from conventional planar dielectrophoresis, utilizes the method can obtain the cluster nano carbon pipe of rising structure.
According to the method, when needing the cluster nano carbon pipe obtaining rising structure, first one object 11 is provided, this object 11 is provided with target hole 11a, this hole can be made according to the method for prior art, as for the arrangement of target hole 11a, can need according to actual the aspect being arranged in matrix or any other realistic user demand.Then the first electrode 10, second electrode 12 is set respectively in object 11 both sides, and makes two electrodes corresponding with target hole 11a.
According to the preferred embodiment of the present invention, this the second electrode 12 is the conductor of a column or needle-like, can certainly be other any shapes, the first electrode 10 can be coordinated to form electric field (or power line), and its diameter preferably comparatively this target hole 11a be little, for controlling the diameter with the leading carbon nanotubes be formed.Certainly, the cross section of this second electrode 12 can also be any geometry, such as ring-type or polygon-shaped.And by second electrode 12 in this different shape cross section, control the shape of CNT (carbon nano-tube) that generates.Preferably be arranged to a plate-like structure above second electrode 12, so that drop pull-up is formed fluid column, increase liquor capacity and the carbon pipe quantity of carrying out dielectrophoresis.
Although it may be noted that the second electrode 12 that embodiment discloses only has an electrode, in the utilization of reality, this second electrode 12 can also coordinate the shape of the arrangement of target hole 11a or array to carry out deploying.Such as, when target hole 11a is arranged in the matrix of standard, then these electric two electrodes 12 can also be arranged in corresponding matrix, to form carbon nanotubes in the target hole 11a that each is corresponding simultaneously.
Next, then the third step dripping the dispersion liquid 13 put containing carbon nanotube powder 13a in this target hole 11a is carried out.And the preparation of the dispersion liquid 13 of CNT (carbon nano-tube) 13a should be contained, then hold and illustrate after a while.
After completing in the target hole 11a of this object 11 dispersion liquid 13 of instillation containing CNT (carbon nano-tube) 13a, just at first and second electrode 10, a suitable alternating voltage is applied to pass this dispersion liquid 13 between 12, with the CNT (carbon nano-tube) 13a in this dispersion liquid 13 integrated in this target hole 11a, to form the integrated bundle 14 of CNT (carbon nano-tube) accumulating pencil, as please refer to shown in Fig. 4.
And as shown in Figure 3 B, during the course, the indivedual CNT (carbon nano-tube) 13a in CNT (carbon nano-tube) dispersion liquid 13 can as Fig. 2 (a), b () be mode shownschematically, gradually under the effect of dielectrophoretic force, move towards centre, and accumulate nano-sized carbon bundle after a certain time.Can see, in Fig. 3 B, for the CNT (carbon nano-tube) dispersion liquid 13 in hole 11a, the electric field of this voltage formation is a vertical electric field, its electric field is vertically, or or rather, is perpendicular in hole 11a and treats the corresponding dispersion liquid containing carbon nanotube powder 13a.
As shown in Figure 4, utilizing the carbon nanotubes that vertical type dielectrophoresis method of the present invention is generated, is a stereochemical structure.The two dimensional surface carbon tubular construction generated with existing use plane formula dielectrophoresis method has great difference, namely first CNT (carbon nano-tube) is made into stereo structure.Therefore its existing range of application can be broken through.
Because CNT (carbon nano-tube) is in the process of dispersion, because the volume of itself and quality are very little, the Fan Dewali between carbon pipe and carbon pipe becomes very powerful in comparison, makes carbon pipe be easy to intertwine.When therefore will do actual assembling application, preferably first processed, the CNT (carbon nano-tube) making each very thin disperses to be separated each other.
According to the present invention, should be with the alcohol of the distilled water+50% of 50% containing preparation of dispersion liquid 13, then add the carbon nanotube powder crossed through overpickling, and carry out ultrasonic waves shake and wash 1.5 hours.Utilize aforesaid mode to carry out the dispersion of CNT (carbon nano-tube), very good effect can be reached.
By the vertical type dielectrophoresis approach application of the present invention's exposure above in electric connector field, as connected the electric connector of CPU and circuit board, a kind of new making method for electric connector and electric connector namely can be obtained.In view of the principle and the product aspect that have detailed vertical type dielectrophoresis method above, hereafter only how simple declaration applies to electric connector field.
Can with reference to the product structure of figure 5 to Fig. 6, first need to provide a substrate 2, this substrate be provided be oppositely arranged upper and lower surperficial 20,22 and run through some holes 24 on upper and lower surface, one first electrode 10 is provided afterwards, be placed on substrate 2 lower surface 22 side, and make this bottom electrode corresponding with some holes 10; Next in each hole 24, the appropriate dispersion liquid 13 containing carbon nanotube powder is instilled from substrate 2 upper surface 20 side respectively; Then one second electrode 12 is provided, is placed on substrate 2 upper surface 20 side, and make this bottom electrode 12 corresponding with some holes 24; Next again, between first, second electrode, apply a predetermined voltage, make the carbon nanotube powder swimming in the CNT (carbon nano-tube) dispersion liquid in this target hole, and then along hole 24 direction boundling slabbing CNT (carbon nano-tube) 14.
It may be noted that, in concrete manufacture electric connector process, not necessarily need as disclosing when telling about vertical type dielectrophoresis Method And Principle, object to be placed on above the first electrode above, this is because we know, the volume of CNT (carbon nano-tube) itself and quality are very little, under electronic building brick high density, compact trend, on instillation substrate, the amount of the dispersion liquid containing carbon nanotube powder of hole is considerably less, and hole is also very tiny, therefore due to siphonic effect, dispersion liquid instillation substrate 2 does not need to worry that it can spill from substrate 2 lower surface 22 side after hole 24.
In the manufacture method of electric connector of the present invention, because the carbon nanotubes that vertical type dielectrophoresis method obtains in the form of sheets, therefore this hole 24 is preferably arranged to finedraw shape.Especially, substrate 2 is provided with the guide channel 26 be connected with hole 24 from upper surface 20 side, and from upper surface on lower surface direction, the funnel-form that this guide channel 26 is big up and small down.The benefit of such setting has: conveniently dispersion liquid is instilled hole 24 on substrate 2; Be convenient to the second electrode 12 of needle-like near finedraw shape hole 24; And be convenient to dock with the CPU containing tin ball.
The manufacture method of the electric connector of the present invention, is also included in the step upper and lower surface affixing respectively one deck viscose 28, naturally these viscoses 28 need corresponding hole 24 be provided with some openings.The object arranging mucigel is: these mucigels can be utilized directly to reach fixing and fixing between electric connector and CPU between electric connector and circuit board.In addition, the CNT (carbon nano-tube) extension that boundling is shaping protrudes from the viscose of lower surface so that dock with the pad on circuit board.
