Abstract
The invention provides a manufacturing method for a capacitive type touch screen, relating to the technical field of the capacitive type touch screen. The manufacturing method provided by the invention comprises the steps of panel preparation, sensor preparation and lead wire preparation. The sensor preparation step comprises the following steps of: 1) transferring a transparent conductive layer and a light resistance layer on a panel in a transfer printing manner; and 2) preparing a sensor panel by exposing, developing, etching and de-molding. The lead wire preparation step comprises the following steps of: pre-setting patterns of a lead wire; printing the pre-set patterns of the lead wire by an ink-jet printer on a prepared belt sensor panel; and curing. With the adoption of the manufacturing method, the purposes of less technique process, convenience in controlling a product quality, and high product yield can be realized.
Description
Technical field
The present invention relates to make the technical field of capacitive touch screen.
Background technology
Present capacitive touch screen need pass through following operation when making, earlier through the panel preparation, prepare sensor and preparation lead-in wire then; The preparation sensor mainly is a plating transparency conducting layer on panel; Through adding photoresist layer post-exposure, development after etching, and demoulding; Preparation lead-in wire so long as on the sensor for preparing first plated film, add the photoresist layer post-exposure then, development after etching, and demoulding.The traditional handicraft technological process is many, equipment investment big, the quality control difficulty is big, product percent of pass is low, demand of human resources is big, causes the price of capacitive touch screen high for a long time, is unfavorable for it and popularizes rapidly.
Summary of the invention
It is few that the object of the invention provides a kind of technological process, is convenient to control product quality, the capacitive touch screen preparation method that product percent of pass is high.
A kind of method for making of capacitive touch screen; Comprise panel preparation, preparation sensor, preparation lead-in wire; Said preparation sensor comprises following steps: 1) mode with trans-printing is transferred on the panel 2 with transparency conducting layer and photoresist layer) make sensor panel through exposure, development, etching, demoulding; Said preparation lead-in wire comprises the steps: pre-set lead pattern, and ink-jet printer is printed on pre-set lead pattern on the belt sensor panel for preparing, and is cured.
Ink-jet printer of the present invention uses the Nano Silver ink special.
The present invention adopts technique scheme, compared with prior art has following advantage:
1, adapt to wide: not only can transfer printing on PC plate, PMMA plate and composite plate, can also on tempered glass, PET panel, shift; Can the light face on the panel.Can also print ICON in advance; Panel can be the plane, can also be on-plane surfaces such as cylinder, formed in mould curved surface;
2, transfer materials is various: not only can transfer printing ITO conductive layer, can also transfer printing nano-silver conductive layer, photoresist layer, or their combination;
3, stable and controllable for quality: material to be transferred is by specialized vendor's prepared in batches on request, and is stable and controllable for quality.
4, equipment is simple, and versatility is good, and production efficiency is high: transfer apparatus is simple, reduces investment; Primary transfer can prepare multilayer (as: conductive layer+photoresist layer), and production efficiency is high; Lead-in wire is printed only needs a special-purpose ink-jet printer, has exempted the making of a large amount of half tones, general convenient; Greatly enhance productivity.
5, simplified working procedures reduces cost: with respect to former flow process, serigraphy has been simplified in this technological process, saves man-hour and personnel, has reduced the unit cost of product, promotes the competitive power of capacitance plate on market, helps capacitance plate and popularizes fast.
Description of drawings
Fig. 1 is the synoptic diagram of method for making of the present invention.
Embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is elaborated:
As shown in Figure 1; A kind of method for making of capacitive touch screen; Comprise panel preparation, preparation sensor, preparation lead-in wire; Said preparation sensor comprises following steps: 1) mode with trans-printing is transferred on the panel 2 with transparency conducting layer and photoresist layer) make sensor panel through exposure, development, etching, demoulding; Said preparation lead-in wire comprises the steps: pre-set lead pattern, and ink-jet printer is printed on pre-set lead pattern on the belt sensor panel for preparing, and is cured.
Ink-jet printer of the present invention uses the Nano Silver ink special.
1, panel preparation: to required state, this comprises reinforcement, surface cleaning with the capacitive touch screen panel substrate preparation, and icon form printing (if necessary);
2, trans-printing: transparency conducting layer that printing transferring methods such as usefulness heat transfer seal will prepare and photoresist layer bat printing are to panel;
3, exposure, development, etching demoulding: the panel with photoresist layer and transparency conducting layer to bat printing makes public, development, harsh demoulding, prepares sensor panel;
4, lead-in wire is printed: on special-purpose ink-jet printer, use the Nano Silver ink special, on the assigned address of panel, pre-designed lead pattern is printed;
5, back operation: this comprises curing, paster, binding and other necessary operation to lead-in wire.
Claims (2)
1. the method for making of a capacitive touch screen; Comprise panel preparation, preparation sensor, preparation lead-in wire; It is characterized in that said preparation sensor comprises following steps: 1) mode with trans-printing is transferred on the panel 2 with transparency conducting layer and photoresist layer) make sensor panel through exposure, development, etching, demoulding; Said preparation lead-in wire comprises the steps: pre-set lead pattern, and ink-jet printer is printed on pre-set lead pattern on the belt sensor panel for preparing, and is cured.
