Description
Technical field
It is espespecially a kind of related using shielding layer the present invention relates to a kind of manufacture method and its construction of touch-control conductive electrode
Step is made metal conducting electrodes and provides construction and method that metal conducting electrodes layer surface completely coats protection, lifting gold at the same time
Belong to the production yield of conductive electrode circuit and the purpose of useful life longevity.
Background technology
Direction with electronics and IT products towards light and shortization is developed, semiconductor making method also towards high density and from
The direction of dynamic metaplasia production is advanced, and the known electronic product or equipment with touch-control sensing face, with its touch-control sensing face or
The size of contact panel product is gradually increased by small, and material is made by the tin indium oxide that generally uses originally in conductive electrode
(ITO) be transformed into metallic conductor electrode, and in its design in order to make the conductive electrode person of being not used of composition panel substrate with
Eyes significantly perceive its presence, that is, do not allow conductive electrode by user depending on recognizing, and cause grinding in the industry at present
Hair personnel are superfine as its target towards the line footpath width of metal conducting electrodes is made.
The actually structure of common metal conductive electrode 10 is with being made, refering to Figure 1, usually step (1) passes through
At least metal conducting electrodes 10 are attached on base material 12 by an adhesion layer 11 (also referred to as following layer), make metal conducting electrodes 10 not
Easily by coming off on base material 12, step (2) then will an at least weathering layer 13 (resist layer) it is laminating in the metal conducting electrodes 10
On, step (3) then recycles etching liquid to be etched program (wet etching) and forms 10 electrode wires of metal conducting electrodes
Road 14, just completes the manufacture of preliminary 10 electrode circuit 14 of metal conducting electrodes, in addition, subsequently in final sensing electrode product
After the completion of, additionally it is possible to spread again with all surfaces for protecting glued membrane 16 (OCA) to carry out 10 electrode circuit 14 of metal conducting electrodes
If.
Refer to shown in Fig. 2, the adhesion layer 11 is designed as two layers, is respectively an intermediary layer combined with the base material 12
17 and the conductive basal layer 18 combined with the metal conducting electrodes 10.
However, Wet-type etching is iso (Isotropic), and because being an etch resistant material in the weathering layer 13
Material, cause the weathering layer 13 and the metal conducting electrodes 10 between the two for etching liquid etch-rate gap very
Greatly, also, the distribution of the weathering layer 13 formed for step (2) is often a pattern in uneven thickness, therefore, etching is worked as
When solution does longitudinal direction etching, probably a serious side etching phenomenon 15 occurs for the metal conducting electrodes 10 among etching process.
Also it is the left and right side part of the metal conducting electrodes 10, especially in other words referring again to shown in Fig. 1
Refer to 10 line footpath of the metal conducting electrodes that width design is less than 5 μm and thickness design is more than 0.3 μ m, it is easier to send out
A raw side etching phenomenon 15, causes the etching total area ratio of the metal conducting electrodes 10 is excessive, etches local inequality to make
Impedance value into 10 electrode circuit of metal conducting electrodes, 14 line footpath is too big, makes the electricity of metal conducting electrodes 10 what is more
The generation of polar curve road 14 one is breaking as a result, the yield and quality of the metal conducting electrodes 10 for being produced manufacturer be not easily-controllable
Pipe, actually superfine conductive electrode processs hand root problem on development makes at present.
Furthermore still further, known 10 electrode circuit 14 of metal conducting electrodes generally used in industrial circle
In the case that line footpath width is superfine, if without further design protection measure, user is for a long time using plus in ambient oxygen
So that 10 electrode circuit of metal conducting electrodes 14 possibly can not reach original predetermined task performance again under change, probably there is contracting
The quality such as short sawn timber service life, the yield for influencing the final contact panel finished product that manufacturer is produced and environment durability
A variety of situations such as performance.
In addition, foregoing known contact panel can carry out a series of environment measuring experiment of strict regulations, such as：It will touch
Control panel carry out 1 it is small when, 85 DEG C, carry out high-temperature heating test experience under 90% humidity, or boiled with 100 DEG C
Boiling carries out one long term high temperature hyperbaric environment of simulation for 100 minutes.
In foregoing two kinds of test experiences instantly, hydrone is penetrated into the protection glued membrane 16, and then touches the gold
Belong to conductive electrode 10, most probably make the metal conducting electrodes 10 that an oxidative phenomena occur, if it follows that user makes for a long time
Produced contact panel is made to foregoing, it forms the impedance value pole of the capacitive sensing of Touch Screen or electronic product can
It can be significantly increased, until one normal operating condition of user can not be supplied.
Have and release bright a variety of known contact panel deficiencies that the metal conducting electrodes 10 produced are made according in foregoing
Lack, actually the purpose of the invention to be improved.
The content of the invention
It is a primary object of the present invention to provide a kind of correlation step of the shielding layer using one with scheduled circuit pattern
The production process of touch-control conductive electrode is made, substitutes known the step of metal conducting electrodes are made with etching technique, reduces and practises
The serious lateral etch phenomenon that the metal conducting electrodes known are occurred in ten program process causes the production of metal conducting electrodes
The extremely low phenomenon of the yields of product.
Another object of the present invention is to carry out complete weathering layer through in the metal conducting electrodes for forming line pattern
The design of protection is coated, user further is greatly reduced in use, conductive electrode is chronically at what aqueous vapor in air was penetrated into
Oxidizing process, strengthens corrosion-resistant effect of conductive electrode, extends the service life of the products of touch-control conductive electrode.
Another object of the present invention is touch-control is made using the correlation step of a shielding layer with scheduled circuit pattern
With the production process of conductive electrode, it can achieve the purpose that management and control and maintain the line footpath width of each touch-control conductive electrode.
A further object of the present invention is that the design of touch-control conductive electrode structure of the present invention and superfine line footpath can be kept away
Exempt from the interference fringe phenomenon (Moire) that human viewable sees to produce, and the light transmittance of increase contact panel light source, raising color
Color saturation degree, reduce color offset phenomenon and other effects, there is provided the comfortable human viewable's touch control operation interface of user one.
For up to the purpose, the manufacture method of touch-control conductive electrode of the present invention, (A) selectes a default base material, by institute
State base material and form a substrate layer, the substrate layer is that have flexible or do not have flexible (rigid)；(B) in the base
An at least adhesion layer is formed in material layer surface；(C) forming one in the attachment layer surface has the shielding layer of grooved lines；(D)
An at least metal conducting electrodes are formed in the grooved lines of the masking layer surface；(E) remove the shielding layer and form a tool
There are the metal conducting electrodes of line pattern and the institute between the metal conducting electrodes line pattern is removed with etching mode
Adhesion layer is stated, and an at least weathering layer is formed on the metal conducting electrodes surface.
Wherein, a weathering layer, institute are formed in the outer circumferential surface of metal conducting electrodes in a preferred embodiment, the step (E)
