Embodiment
Of the present invention being contemplated that adopts plating molybdenum or plating molybdenum, aluminium, molybdenum to replace common silver slurry cabling of the prior art.For making goal of the invention of the present invention, technical scheme, effect clearer, below in conjunction with accompanying drawing, the present invention is described in detail by specific embodiment.
Embodiment one
The method for making of the multi-point electric resistance formula touch-screen in the present embodiment comprises the steps:
1) plating molybdenum:
Plating one deck molybdenum 3 on the ITO of glass substrate 1 layer 2; The plating molybdenum technological process of this step is referring to Fig. 3, and plating molybdenum principle by the plasma sputtering mode, is deposited on base plate glass on film forming with target atom referring to Fig. 4.
2) molybdenum cabling:
Realize the molybdenum cabling by molybdenum gluing, molybdenum exposure, molybdenum development, molybdenum etching, molybdenum demoulding;
3) ITO cabling:
After the molybdenum cabling is finished, realize the ITO cabling by gluing, exposure, development, harsh, demoulding again, at last with the glass substrate with ITO layer 1 of touch-screen and the film 4 by two-sided sticking 5 coupling together in the box, finish the making of whole touch screen.The multi-point electric resistance formula touch-screen that the method for making of multi-point electric resistance formula touch-screen of the present invention obtains is referring to Fig. 5;
In the present embodiment, behind glass substrate plating molybdenum, control the live width of molybdenum cabling and ITO cabling by exposure: the plating molybdenum wire is wide to be controlled in the scope of 5 μ～20 μ, as being 10 μ, referring to Fig. 6, the molybdenum cabling space is 2.92mm, because the control of the precision of exposure is high, so the molybdenum trace width is easy to control, function corresponding is bad very low.
