Abstract
The invention discloses an anisotropic electric conduction adhesive tape/film, which comprises a first adhesive material layer, a metal thin film layer and a second adhesive material layer, wherein the first adhesive material layer and the second adhesive material layer are formed respectively from an insulating adhesive and a lot of electric conduction particles, the electric conduction particles are distributed in the insulating adhesive, the metal thin film layer has two opposite side surfaces, and the first adhesive material layer and the second adhesive material layer are respectively arranged on both side surfaces of the metal thin film layer. The anisotropic electric conduction adhesive tape/film has characteristics of good stability, low resistance, low deformation rate during punching, increased yield, and substantially reduced cost.
Description
Technical field
The present invention relates to a kind of anisotropic conductive tape/film.
Background technology
In the market conductive tape/film, mainly contain following three kinds:
A, coventional type conductive tape/film are conductive powders (being mainly nickel powder) with after pressure-sensitive glue mixes, and are coated on separate-type paper, and rolling forms after drying.
B, coventional type anisotropic conductive tape/film are mainly to be blended in pressure-sensitive glue with a large amount of metal-powders or electroconductive powder, are coated on separate-type paper/film, make after drying adhesive tape/film.Its cardinal principle is accumulation, the contact that utilizes highdensity conductive powder mutual, thereby forms omnibearing conductive effect.
C, on the basis of B, middle steam to cross or spatter cross one deck conductive layer, thereby make anisotropic conductive tape/film.
But all there is certain defective in above three kinds of conductive tape/films:
1) A can only conduct electricity up and down, can not conduct electricity on the plane, thereby does not have the function of plane conduction.
2) B, can be because the stretching of adhesive tape/film makes the conductive powder spacing of close packing strengthen in actual production is used, and contact reduces, and increases thereby produce impedance, or loses the plane conductive effect.In addition, because it is a kind of elasticity self-adhesion colloid, and the centre does not have metal support structure, therefore in the production stamp process of reality, easily is out of shape the poor stability of size yet.
3) C slightly is improved than B, but spatters layer in the middle of C, no matter be that evaporation or sputter are all very crisp, and easy cracking, thus planar resistor is increased, and cost is high, complex procedures, yield are low.
In a word, B, C all have characteristics, and they have used a large amount of conductive powders, the heavy metal contamination of environment have been played the effect of adding fuel to the flames, because the manufacturing of various conductive powders is all the technique high with contaminative of power consumption.Thereby owing to having used a large amount of conductive powders, cause the self-adhesive ratio to diminish, thereby clinging power and the confining force of adhesive tape/film have been affected.
Summary of the invention
In order to overcome defects, the invention provides a kind of anisotropic conductive tape/film, this anisotropic conductive tape/film is not only stable, has lower resistance, and deformation rate is low during stamp, and yield improves, and cost also reduces greatly in addition.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of anisotropic conductive tape/film, comprise the first glue material layer, metal film layer and the second glue material layer, described the first glue material layer and the second glue material layer are formed by insulation paste and a plurality of conducting particles respectively, and described conducting particles is distributed in this insulation paste; Described metal film layer has two relative sides, and described first and second glue material layer is located at respectively on two sides of this metal film layer.
As a further improvement on the present invention, described metal film layer is one of Copper Foil, aluminium foil and silver foil.
As a further improvement on the present invention, the thickness of this anisotropic conductive tape/film is 0.02mm-2mm.
As a further improvement on the present invention, the contact surface of described metal film layer and described the first glue material layer and the second glue material layer all is curved surface.
As a further improvement on the present invention, described insulation paste is pressure-sensing glue.
As a further improvement on the present invention, be respectively equipped with one deck separate-type paper/rete at described the first glue material layer and the second glue material layer on the side away from described metal film layer.
The invention has the beneficial effects as follows: at the therebetween last layer metal film layer of former conductive tape/film, utilize ductility, dimensional stability and the omnibearing electroconductibility of metal, thereby set up impact-resistant cube conductive structure, it is anisotropic conductive tape/film, it is not only more stable, during punching press, deformation rate is low, easily waste discharge in punching course; And the conductive powder usage quantity greatly reduces, and reduces costs, and reduces and pollutes; In addition, resistance is also lower, and conductive stability is high, and the thickness range that product can be made is also very large.In a word, this anisotropic conductive tape/film have that thickness range is large, deformation rate is low, dimensional stability is good, low resistance and can comprehensive plane conduction etc. excellent properties.
Description of drawings
Fig. 1 is structural representation of the present invention.
By reference to the accompanying drawings, make the following instructions:
1---first glue material layer 2---metal film layer
3---second glue material layer 4---separate-type paper/rete
5---insulation paste 6---conducting particles
Embodiment
As shown in Figure 1, a kind of anisotropic conductive tape/film, it is followed successively by separate-type paper/rete 4, the first glue material layer 1, metal film layer 2, the second glue material layer 3 and separate-type paper/rete 4 from top to bottom, wherein the first glue material layer and the second glue material layer are formed by insulation paste 5 and a plurality of conducting particles 6 respectively, and conducting particles 6 is distributed in this insulation paste 5.Wherein, metal film layer can be the conductive metal films such as Copper Foil, aluminium foil or silver foil, and insulation paste is pressure-sensing glue.The thickness of this anisotropic conductive tape/film can be between 0.02mm-2mm.This anisotropic conductive tape/film due to the squeezing action of the conducting particles in first and second glue material layer, makes the contact surface of first and second glue material layer and metal film layer form curved surface in the impact briquetting process.
Get the vertical resistivity test after anisotropic conductive tape/film commonly used on this anisotropic conductive tape/film and market carries out respectively resistance test, Elongation test and stretching, its test result is as shown in the table:
Can find out from above-mentioned test result, this product has the advantages such as resistance is low, and stability is high, and is not yielding.
