The specific embodiment
Spray the aspect graph that forms conductive layer for anisotropic conductive film preparation method's of the present invention flow chart and the present invention as depicted in figs. 1 and 2, the manufacture method of anisotropic conductive film 14 comprises following three steps successively: (a) have coating one deck insulative resin 11 on the support 10 of resin bed at resin-made membrane or surface; (b) liquid component that contains metal conductive particles that will make from liquid droplet ejecting head is ejected into the resin bed formation conductive layer 12 that step (a) forms; (c) coating one deck insulative resin 13 on the conductive layer 12 that step (b) forms.
Compositions such as antiseize resin that described coating ground floor insulating resin is a class such as silicone oil resin, polyamide, oleamide and antistatic additive, antistatic additive mainly is based on nonionic and cationic surfactant, the compound of main employing hydroxyethylation fatty amine, quaternary amine, fatty acid ester antistatic additive etc., the composition of each component is by weight:
100 parts of antiseize resins
Antistatic resin 1-5 part.
The used decentralized medium of liquid that described liquid droplet ejection apparatus sprays must be oil-soluble, as long as can the dispersed electro-conductive particle and do not produce caking, employed decentralized medium is not had special restriction, and its composition mainly contains aliphatic alcohol, aliphatic ester, organic solvent (as alcohols, hydro carbons, ether, ester, ketone etc.), cationic surfactant etc.
The used conducting particles of liquid component in the liquid droplet ejection apparatus so long as the good metallic of electric conductivity all may be utilized, the conductive micro-balloons described in application for a patent for invention number 200510018992.1 patents for example, its seed that to be vinyl monomer make with the method for non-aqueous suspension polymerization is a styrene at polymerization single polymerization monomer, methyl methacrylate, AMS, vinyl monomer and glycol diacrylates such as methyl acrylate, the diglycol diacrylate, ethylene glycol dimethacrylate, cross-linking monomer mixed emulsions such as diglycol dimethylacrylate carry out method of emulsion polymerization and make that to have cross-linked polymer be shell, the lower molecular weight polymer is the polymer microballoon of core, polymer microballoon plating nickel on surface and gold with above-mentioned preparation obtains the electric conductive polymer microballoon then, and the composition of each component is by weight:

As long as can reach the accuracy of setting, above-mentioned steps (a), (c) can adopt common coating method, as: the layer 13 that step (c) forms is thinner than the layer 11 that step (a) forms, and represents thickness with alphabetical t, t
13=revolve 0.5～0.95t such as getting rid of rubbing method, knife coating, anilox roll method
11, this is because drop is ejected into solvent scattering and permeating effect (seeing the 3C among Fig. 3), the bottom portion embeding layer 11 (seeing the 3D among Fig. 3) of the conductive layer that droplet drying forms to be arranged before the drying on the layer 11.According to actual needs, also allow evenly to disperse the part conductive compositions in layer 11, the layer 13.
In fact jet printing has taken place in above-mentioned steps (b), after liquid droplet ejection apparatus receives the working signal that TCE terminal control element sends, beginning is sprayed along straight line, and repeats by setting constantly, finally sprays the linear fringe shape (seeing the 3E among Fig. 3) that the conductive layer that forms is orderly arrangement.
Liquid droplet ejection apparatus of the present invention configuration be single shower nozzle, shower nozzle moving linearly only during injection is so can obtain continuous preferably injection conductive layer.
Liquid droplet ejection apparatus of the present invention should adopt the random mode spraying technique, and it just begins to spray along straight line after only receiving the working signal that TCE terminal control element sends.The present invention also can adopt the continous way spraying technique, compare with random mode have complex structure, separately retracting device be set, shower nozzle needs the efficient of pressue device and working method not high enough, and it is accurate inadequately, and the random mode spraying technique can overcome the problems referred to above, is the best spraying technique that the present invention should adopt.This spraying technique significantly also has application in the printer in HP Designjet 30 grades.
What liquid droplet ejection apparatus of the present invention used is little piezoelectric type shower nozzle, and the shower nozzle diameter is at 8～25 microns.Micro Piezo technology is divided into 3 stages to the control of the drop in the course of injection: before the spraying, piezoelectric element at first shrinks under the control of signal slightly; Then, element produces once bigger extension, and drop is released shower nozzle; In the moment that drop will fly away from shower nozzle, element can shrink again, and clarity ground shrinks the drop liquid level from shower nozzle at once.Like this, the drop liquid level has obtained accurate control, and the drop of each ejection all has perfect shape and correct heading.
The basic demand of the liquid component that liquid droplet ejection apparatus of the present invention sprays is that low surface tension, low viscosity, relative density are little, and drying property is fast etc., and pH value is neutral basically, avoids corroding shower nozzle.Comprise conducting particles in the liquid component that liquid droplet ejection apparatus of the present invention sprays, conducting particles is as long as electric conductivity is good, there is no particular restriction, metallic, as nickel, iron, copper, aluminium, tin, lead, cobalt, gold, silver, palladium, titanium, rhodium etc., metal oxide, carbon, graphite and have glass, pottery, plastic pellet of metal outer etc.The diameter of conducting particles is preferably between 0.1 μ m～10 μ m.If the diameter of conducting particles greater than 10 μ m, stops up shower nozzle easily during injection, if less than 0.1 μ m, then conduction is bad.The mass percentage concentration of conducting particles is preferably 20%～80%.The viscosity of the liquid component that liquid droplet ejection apparatus of the present invention sprays is moderate, and the too big injection of viscosity is not smooth, stops up shower nozzle easily yet, and too Xiao Yi produces damped oscillation, influences jet velocity, and its optimum range is 0.0015～0.0035pas.The surface tension of the liquid component that liquid droplet ejection apparatus of the present invention sprays preferably between 0.02～0.05N/m, its surface tension too greatly, the too little accuracy of spray that all influences.Be advisable less than 0.2 second the drying time of the liquid component that liquid droplet ejection apparatus of the present invention sprays.
