Embodiment Construction

[0013] The present invention will be further described below in conjunction with embodiment. The model of the sticky roller electrostatic cleaning machine selected by the present invention is: DY-CR650; the model of the laminating machine is: DY-LS700; the model of the vacuum packaging machine is: DZQ600-2D.

[0014] A kind of touch screen silver line anti-oxidation method concrete steps are as follows:

[0015] (1) Clean the ITO film printed with silver lines through the sticky roller electrostatic cleaner, set the pressure: 2kgf / cm2; transfer speed: 3m / min;

[0016] (2) Pass the ITO film printed with silver lines cleaned by the sticky roller electrostatic cleaner through the laminating machine to cover the protective film on both sides, with the printing side facing up. The models of the upper and lower protective films of the laminating machine are: HP -508 and KB-10H, set the laminating machine pressure: 3kgf / cm2; conveying speed: 2m / min;

[0017] (3) Repeatedly clean th...

Abstract

The invention relates to an anti-oxidation method of touch screen silver wires, which comprises the following steps that: 1. ITO (indium tin oxide) films printed with silver wires are cleaned by a sticky roller electrostatic cleaning machine; 2.the double sides of each ITO film printed with the silver wires cleaned by the sticky roller electrostatic cleaning machine are laminated with protective films by a laminating machine; 3. the surface of a stainless steel plate is repeatedly cleaned by a dust-free cloth moistened with alcohol; 4. the ITO films printed with the silver wires with the laminated protective films on the double sides are tidily stacked in the stainless steel plate; 5. the stainless steel plate is put in a vacuum bag; 6. the vacuum bag with the stainless steel plate is putin a vacuum packaging machine to be vacuumized and plastic-packed; 7. the vacuumized and plastic-packed stainless steel plate is taken out of the vacuum packaging machine. The anti-oxidation method of the silver wires is applied to the machining process of a touch screen sensor device; so that the problem that materials are scraped in bulk because of instable electrical properties of the device caused by the oxidation of the silver wires can be effectively reduced or eliminated.

Description

technical field [0001] The invention relates to a method for storing semi-finished products of touch screen sensor devices, in particular to a method for preventing oxidation of silver wires of a touch screen. Background technique [0002] Touch screens used in today's electrical and electronic equipment generally include the following five types: resistive, surface capacitive, projected capacitive, surface acoustic wave, and infrared. No matter what kind of touch screen is made, it is inseparable from printing on indium tin oxide (ITO) substrate. The printing on the ITO substrate is mainly divided into etching ink printing and silver paste printing, and the silver wire formed after the silver paste is printed on the ITO surface is an important conductive line connecting the FPC flexible circuit tail wire and the ITO line, the quality of the silver wire It is an important factor affecting the electrical performance of the touch screen. The main component of silver paste i...
