Description
Technical field
The present invention relates to touch screen technology field, relate in particular to a kind of method for making of fexible film functional sheet.
Background technology
Fexible film (film) functional sheet is one of core component of capacitive touch screen, can be also one of key component of following flexible display device.Film functional sheet, taking flexible transparent conducting film as base material, comprises ito thin film, nanometer silverskin and graphene film, is processed into functional sheet by certain processing step, then connects circuit and just has touch function.The main method for making of existing fexible film functional sheet comprises: wire mark method for making, laser etching method and takeup type gold-tinted method for making.
Wire mark method for making is by serigraphy, on the ito thin film sheet material cutting in advance in slices, print acid-proof ink or ITO etching paste, and then carry out etching and cleaning, silk-screen edge-silver cabling more afterwards, then by cut or be die-cut into small pieces one by one, just obtain film functional sheet in conjunction with follow-up binding flexible print circuit (FPC).The defect that wire mark method for making exists comprises: 1, serigraphy ITO circuit is wider, is generally 200 microns of left and right, then runs business into particular one and just have any problem, and causes film functional sheet insufficient sensitivity high; 2, the film functional sheet that serigraphy is made can not do two-layer ITO circuit, can not on a slice ito thin film, be X, Y circuit simultaneously; 3, serigraphy requires highlyer to operating environment, in manufacturing process, because half tone is easily because dust or fine particles cause to be opened circuit, and then affects function; 4, serigraphy, in large stretch of printing process, is difficult to ensure that the silk-screen of each small pieces is qualified, and yield is low; 5, no matter acid-proof ink or ITO etching paste of serigraphy, has denseer smell, not environmental protection.
Laser etching method is to utilize high power laser to carry out etching, and it mainly comprises after sawing sheet section material, laser ablation, silk-screen silver slurry, laser ablation silver cabling, cutting the process such as binding.For the film functional sheet of nanometer silverskin and graphene film, can only adopt laser etching method, and be not suitable for adopting wire mark method for making.The defect that laser etching method exists comprises: in 1, laser-induced thermal etching process, dust is many, clear up timely dust, and laser instrument could be worked smoothly; 2, laser-induced thermal etching efficiency in the time making small pieces is higher, but efficiency is relatively low for large-sized functional sheet, and especially, for 7 cun of above large scale touch-screens, laser-induced thermal etching efficiency is very low.
And takeup type gold-tinted method for making mainly comprises that coiled material cleans and is coated with the exposure of photoresistance, coiled material, coiled material develop cleanings, coiled material etching stripping, plating or silk-screen silver slurry and the process such as gold-tinted or the silver-colored cabling of laser ablation again.The defect that takeup type gold-tinted method for making exists comprises: 1, every procedure all needs to adopt Special Equipment, wherein there is cleaning equipment, be coated with photoresistance equipment, exposure sources, development cleaning equipment and etching membrane stripping device etc., comparison in equipment is many, equipment investment is larger, cost of manufacture is high, and product accuracy cannot ensure; 2,, because be the processing of entire volume, middle quality cannot ensure, is not so good as sheet material so flexible.
Summary of the invention
Technical matters to be solved by this invention is, a kind of method for making of fexible film functional sheet is provided, and it can make nesa coating quickly and easily, and cost is lower.
For solving the problems of the technologies described above, the invention provides following technical scheme: a kind of method for making of fexible film functional sheet, comprises the steps:
Cutting step, cuts into nesa coating and UV glue respectively and transparency carrier size of the same size;
Laminating step, is attached to described nesa coating on transparency carrier by means of described UV is gluing, forms semi-manufacture;
Conventional machining step, sequentially cleans the semi-manufacture that post conventional machining operations such as being coated with photoresistance, exposure imaging, etching, stripping, forms predetermined circuit on nesa coating;
UV irradiating step, the product that adopts UV light irradiation to process, reduces UV tackiness;
Separate, cut and binding step, the nesa coating that is formed with scheduled circuit is peeled from transparency carrier, after finally cutting, binding, obtain fexible film functional sheet finished product.
Further, in described conventional machining step, adopt gold-tinted processing procedure to form predetermined circuit.
Further, described transparency carrier is glass substrate.
Further, described transparency carrier thickness is 1.0-1.5mm.
Further, described UV glue is UV adhesive layer or UV double faced adhesive tape.
Adopt after technique scheme, the present invention at least has following beneficial effect: the present invention is by utilizing UV glue that sheet material transparent conductive film is sticked on the glass substrate or other transparent plate substrates that thickness is 1.0mm-1.5mm, can carry out easily follow-up manufacturing procedure, avoid nesa coating due to softness relatively and the defect of processing difficulties, after machining, also can also easily the fexible film functional sheet processing be peeled to cut from transparency carrier, binding processing, whole process is very convenient quick, make efficiency and product yield are all higher, and also recyclable recycling of transparency carrier, use cost is low.
The present invention also can coordinate gold-tinted processing procedure system to produce the meticulousr functional sheet of circuit, and fine-line live width can be accomplished 10 microns of left and right, and touch sensitivity is higher, can utilize the equipment of existing gold-tinted processing procedure, without dropping into new equipment; In addition, can also on a slice nesa coating, be the X of functional sheet, Y circuit, realizes real multi-point touch; In addition, due to gold-tinted making technology, compare takeup type gold-tinted technique, its operation is continuous, the fine control of degree of accuracy, efficiency and the yield of producing functional sheet are higher, compare serigraphy and laser-induced thermal etching, functional sheet circuit is meticulousr, and touch sensitivity is high, and safer environmental protection.
