Description
Technical field
The utility model relates to a kind of anisotropic conductive adhesive tape/film.
Background technology
In the market conductive tape/film, mainly contain following three kinds:
A, coventional type conductive tape/film are conductive powders (mainly being nickel powder) with after pressure-sensitive glue mixes, and are coated on the separate-type paper, and rolling forms after dry.
B, coventional type anisotropic conductive adhesive tape/film mainly are to be blended in the pressure-sensitive glue with a large amount of metal-powders or electroconductive powder, are coated on separate-type paper/film, after drying, make 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 process anisotropic conductive adhesive 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, and also easy deformation, size stability is poor.
3) C slightly improves than B, but the C intermediary spatters layer, no matter be that vapor deposition or sputter are all very crisp, and easy of crack, thus planar resistor is increased, and cost height, complex procedures, yield are low.
In a word, B, C all have characteristics, and they have used a large amount of conductive powders, and the effect of adding fuel to the flames has been played in the heavy metal contamination of environment, because the manufacturing of various conductive powders all is the technology high with contaminative of power consumption.Thereby, cause the self-adhesive ratio to diminish, thereby influenced the clinging power and the confining force of adhesive tape/film owing to used a large amount of conductive powders.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of anisotropic conductive adhesive tape/film, and this anisotropic conductive adhesive 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 utility model for the technical scheme that solves its technical problem and adopt is: a kind of anisotropic conductive adhesive tape/film; Comprise the first glue material layer, metal film layer and the second glue material layer; The said first glue material layer and the second glue material layer are formed by insulation paste and a plurality of conducting particles respectively, and said conducting particles is distributed in this insulation paste; Said metal film layer has two relative sides, and said first and second glue material layer is located at respectively on two sides of this metal film layer.
As the further improvement of the utility model, said metal film layer is one of Copper Foil, aluminium foil and silver foil.
As the further improvement of the utility model, the thickness of this anisotropic conductive adhesive tape/film is 0.02mm-2mm.
As the further improvement of the utility model, the contact surface of said metal film layer and the said first glue material layer and the second glue material layer all is curved surface.
As the further improvement of the utility model, said insulation paste is a pressure-sensing glue.
As the further improvement of the utility model, on the said first glue material layer and second side of glue material layer, be respectively equipped with one deck separate-type paper/rete away from said metal film layer.
The beneficial effect of the utility model is: 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, i.e. anisotropic conductive adhesive tape/film, it is not only more stable; Deformation rate is low during punching press, is prone to waste discharge in the punching course; And the conductive powder usage quantity significantly reduces, and reduces cost, 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 big.In a word, this anisotropic conductive adhesive tape/film have that thickness range is big, deformation rate is low, dimensional stability is good, low resistance and can comprehensive plane conduction etc. excellent properties.
