Abstract
The invention provides a touch screen ITO (Indium Tin Oxide) glass screen printing process. The touch screen ITO glass screen printing process is characterized in that the process comprises the following steps: 1) ITO glass cutting; 2) screen-printing acid-resistant ink; 3) etching and demolding; 4) screen-printing a supporting point; 5) screen-printing an IR (Infrared) high-transparent insulating oil FR-1T-CK in a non-acting area in a visible area of a touch screen; 6) screen-printing protection glue; 7) screen-printing a silver line; 8) screen-printing IR semi-transparent insulating oil CR-18T-CR in a silver line printing area. The touch screen ITO glass screen printing process provided by the invention has the advantage that the performance stability and the yield of the touch screen ITO glass can be improved.
Description
Technical field
The present invention relates to a kind of touch-screen production technology, particularly relate to touch-screen ito glass silk screen printing process.
Background technology
In the production process of touch-screen, after the complete silver-colored line of touch-screen silk-screen solidifies, meeting silk-screen one deck insulating oil on silver-colored line, is for improving the insulating capacity between the silver-colored line of upper and lower layer on the one hand; Be for isolated silver-colored line contacts with extraneous air on the other hand, prevent oxidation and soak tide, ensure the unlikely reduction of insulating capacity.
Under existing technical situation; ito glass silk screen printing process is: ito glass sawing sheet → silk-screen is acidproof → and the high insulating oil thoroughly of etching demoulding → silk-screen strong point → silk-screen protection glue → silk-screen silver line → silk-screen; that is to say; after the complete silver-colored line of ito glass silk-screen of touch-screen solidifies; non-active region in silver-colored line region and the visible area of product; the high insulating oil FR-1T-CK thoroughly of silk-screen one deck IR type, contacts with extraneous air with the insulating capacity and the isolated silver-colored line that improve between the silver-colored line of upper and lower layer.But, silk-screen the high ito glass of insulating oil FR-1T-CK thoroughly of IR type, after reliability test (containing thermal shock and High temperature storage), can produce ito glass loop resistance and become large, ito glass easily produces linear bad, its reason is in the process of reliability test, the high insulating oil FR-1T-CK thoroughly of IR type pulls effect to covered ito glass silver line, make ito glass silver line and the loose contact of ITO layer, cause that contact resistance between silver-colored line and ITO becomes large, ito glass loop linearity is bad, the ito glass unstable properties that causes touch-screen, yields is low.
Summary of the invention
The object of this invention is to provide a kind of touch-screen ito glass silk screen printing process, this touch-screen ito glass silk screen printing process can improve stability and the yields of touch-screen ito glass performance.
In order to achieve the above object, touch-screen ito glass silk screen printing process of the present invention, is characterized in that its technological process comprises the steps:
1., ito glass sawing sheet;
2., silk-screen is acidproof;
3., etching demoulding;
4., the silk-screen strong point;
5., the high insulating oil FR-1T-CK thoroughly of the non-active region silk-screen IR type in touch-screen visible area;
6., silk-screen protection glue;
7., silk-screen silver line;
8., the semi-transparent exhausted oily CR-18T-CR of silk-screen IR type in silver-colored line Printing Zone.
Because in touch-screen ito glass silk screen printing process of the present invention, the semi-transparent exhausted oily CR-18T-CR of silk-screen IR type in silver line Printing Zone, instead of the high insulating oil FR-1T-CK thoroughly of IR type, just do not have the pull effect of the high insulating oil FR-1T-CK thoroughly of IR type to ito glass silver line, both made after the process of reliability test (containing thermal shock and High temperature storage), ito glass silver line also can contact well with ITO layer, contact resistance value stabilization, ito glass loop good linearity between silver line and ITO, the stability that has improved touch-screen ito glass performance, yields is high.
Touch-screen ito glass silk screen printing process of the present invention, can improve stability and the yields of touch-screen ito glass performance.
Brief description of the drawings
Fig. 1 is the flow chart of touch-screen ito glass silk screen printing process of the present invention.
Detailed description of the invention
Referring to Fig. 1, the embodiment technological process of touch-screen ito glass silk screen printing process of the present invention is: ito glass sawing sheet → silk-screen is acidproof → etching demoulding → silk-screen strong point → and the high insulating oil FR-1T-CK thoroughly → silk-screen of non-active region silk-screen IR type protection glue → silk-screen silver line → semi-transparent exhausted oily CR-18T-CR of silk-screen IR type in silver-colored line Printing Zone in touch-screen visible area.
Because the semi-transparent exhausted oily CR-18T-CR of silk-screen IR type in silver-colored line Printing Zone, instead of the high insulating oil FR-1T-CK thoroughly of IR type, just do not have the pull effect of the high insulating oil FR-1T-CK thoroughly of IR type to ito glass silver line, both made after the process of reliability test (containing thermal shock and High temperature storage), ito glass silver line also can contact well with ITO layer, contact resistance value stabilization, ito glass loop good linearity between silver line and ITO, improved the stability of touch-screen ito glass performance, and yields is high.
Touch-screen ito glass silk screen printing process of the present invention can improve the stability of touching screen ito glass performance, and yields is high.Applying of it, improves and has positive meaning the performance of touch-screen ito glass.
