Embodiment Construction
[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.
[0033] A method of screen printing for making a projected capacitive touch screen, such as figure 1 Shown, concrete steps of the present invention are:
[0034] Step 1. Place the clean scratch-resistant PET substrate on the stencil printing platform with the scratch-resistant surface facing down. A PET_X film 5 is formed. The PET base material with the protective layer of the release film is placed on the stencil printing platform 4 with the release film facing down to form a PET_Y film 6 . The PET_X film 5 and the PET_X film 6 are precisely positioned and placed on the stencil printing platform 4 by the mechanical arm. In view of the fact that the high-transparency PET film is used as the substrate of the touch screen, the screen can be bent; it can be attached to a curve...

The solution is a silk-screen printing technology for making a projection-type capacitance touch screen, comprising the following steps: step 1) placing a clean scratch-resistant PET substrate on a steel mesh printing platform; step 2) pasting a flexible drifting circuit board on a PET-X film with a robotic arm; step 3) entering into a printing area of the steel mesh printing platform, wherein a steel mesh is directly reduced via a mechanical lifting device and is covered on the surface of PET-X film and a PET-Y film; step 4) lifting the steel mesh via the mechanical lifting device, wherein the PET-X film and the PET-Y film enter into a heat-agglomerating area of a assembly line; step 5) entering into an insulating treatment device and evenly coating transparent insulation paste which is 12 to 18 microns thick on the PET-X film and the PET-Y film; step 6) entering into laminating equipment to press the PET-X film and the PET-Y film together which are finished in the step 4) and controlling the pressing temperature as 70 to 110 degrees centigrade. Through using a steel mesh printing technology, the silk-screen printing technology of the invention is fast in printing speed, high in image precision and fine in image line.
Description
technical field [0001] The invention belongs to the fields of stencil printing, digital modeling, laser application and the like, and in particular relates to a screen printing method for making a projected capacitive touch screen. Background technique [0002] Projected capacitive touch screen is a kind of sensing film mainly encapsulated with fine wires. It integrates the advantages of precise sensing positioning, flexibility and high transparency. It is used for precise touch positioning of touch screens above 12 inches, and is also used in precise Interactive projection. [0003] Projected capacitive technology is a kind of horizontal and vertical electrode arrays made on the surface of glass or transparent film. These horizontal and vertical electrode capacitance changes are used to detect finger touches. According to the difference in capacitance generation, it is divided into two types: Types of: [0004] Self-capacitance screens are made of transparent conductive m...
