Abstract
The invention relates to a manufacturing method of a metal logo on a single-layered glass capacitive touch screen, comprising the designed steps of: washing and cleaning a touch screen semi-finished product with an ITO (Indium Tin Oxide) pattern; adopting vacuum sputtering to continuously plate a metal MOALMO (Molybdenum-Aluminum-Molybdenum) thin film; coating photo-sensitive resist on a yellow light section, and drying and hardening; utilizing an exposure machine to expose; utilizing an alkaline solution to develop and etch a metal pattern; and stripping the photo-sensitive resist, wherein a formed metal pattern region comprises a metal frame cabling, a metal bridging region and a logo position. The manufacturing method has the beneficial effects that screen printing of a logo of an OGS (One Glass Solution) touch screen is finished by a metal film plating manner for one time and screen printing silver slurry is not needed; meanwhile, the logo has a metal texture, one time of a silver slurry screen printing procedure is reduced, the yield is improved and the cost is reduced; and therefore, the manufacturing method has very high popularization value.
Description
Technical field
The present invention relates to surface decoration technique, particularly the method for making of metal logo (sign) on a kind of single-glass capacitive touch screen.
Background technology
Along with popularizing of capacitance touch screen mobile phone, each large mobile phone TP(touch-screen) manufacturer is all in the new technology of exploitation, to reduce cost, Promote Competitive; The ripe solution plan of capacitive touch screen has G+G (glass is to glass structure) at present, and G+F(glass is to membrane structure).More low-cost in order to realize, lighter, penetrance is better, each TP merchant begins to drop into OGS(One glass solution-sheet glass solution at present) research and development, the inducing function layer is made in Cover LENS(glass cover-plate) on, can save glass to the applying of glass, use less simultaneously a glass, cost declines to a great extent, and yield also obviously improves.At present way is that sheet is made, and namely is made into large stretch of TP(touch-screen by gold-tinted and coating process first), then cut into small pieces, the CNC(carving machine) process after through secondary hardening, silk-screen silver slurry logo (sign) afterwards.And silver slurry cost is expensive, also needs out the grinding tool half tone, and the present invention can lack the silk-screen operation one time, the cost decrease, and yield can reduce the loss of several points.
Summary of the invention
The method for making that the purpose of this invention is to provide metal logo (sign) on a kind of single-glass capacitive touch screen, single-glass touch-screen silk-screen logo (sign) adopts the mode of metal-coated membrane once to finish, and no longer needs silk-screen silver slurry.The present invention adopts the plated film mode to make logo (sign), has equally metal-like, be coated with metal film and silk-screen silver slurry same effect is arranged, and the magnetron sputtering metal-coated membrane operation that is absolutely necessary, the characteristics of this operation are once to finish touch-screen frame metal routing, metal bridge through gold-tinted and etch process behind the plated film
And metal logo (sign).Lack like this a silk-screen operation, yield can improve, and cost can reduce.And adopt method making logo (sign) the comparison screen printing method of vacuum sputtering coating that better adhesion property is arranged.
The technical scheme that the present invention takes is: the method for making of metal logo (sign) on a kind of single-glass capacitive touch screen is characterized in that: comprise following design procedure:
A) clean up carry out the ITO(tin indium oxide) the touch-screen semi-manufacture of figure;
B) adopt the vacuum sputtering continuous gold-plating to belong to MOALMO(molybdenum aluminium molybdenum) film, ground floor MO(molybdenum) thickness 20nm ± 3nm, second layer AL(aluminium) thickness 180nm ± 5nm, the 3rd layer of MO(molybdenum) thickness 20nm ± 3nm;
C) be coated with photoresists and toast post bake in the gold-tinted section, coating positive-working photoresist thickness 1.2um, 120 ℃ of baking 10min;
D) with exposure machine exposure, exposure 60mj/cm
2, time 2s, illumination 30mw/ cm
2
E) develop with alkali lye; Concentration is 0.8%NaOH development time 80s;
F) etch metallic pattern;
G) peel off photoresists;
H) the metallic pattern zone that forms comprises the metal edge frame cabling, metal bridging zone and logo (sign) position.
Beneficial effect of the present invention is: OGS touch-screen silk-screen logo (sign) adopts the mode of metal-coated membrane once to finish, do not need again silk-screen silver slurry, adopt the plated film mode to make logo (sign), has equally metal-like, few silk-screen silver slurry process, yield can improve, and cost can reduce, and has very high promotional value.
