Embodiment 1

[0016] A method for manufacturing a nanoparticle membrane switch. The polyester screen plate is fixed on a screen printing machine, and the conductive silver paste is printed on a 0.075 mm thick corona-treated ZnO nanoparticle film by a scraper, and then placed Curing in an oven at 80-120°C for 25-35 minutes; after the conductive silver paste layer is cured, use a polyester screen to print a layer of light-curable insulating ink on the non-contact silver paste line, and pass through the ultraviolet light channel of the UV exposure machine Complete curing; print 19 brushes a layer of conductive carbon paste on the conductive silver paste circuit connected externally; use a laser cutter or mold to cut the ZnO nanoparticle film according to the shape of the membrane switch, and the middle layer of 0.1 mm thick ZnO nanoparticle film in the The contact parts of the corresponding upper and lower points are also cut off; finally, the upper, middle and lower three-layer films are assem...

Embodiment 2

[0018] In the manufacturing method of the nanoparticle membrane switch described in Example 1, the process parameters of the screen printing machine are all selected: the pressure applied to the screen by the squeegee is 0.3-0.4 MPa, and the speed of the squeegee printing movement is 0.2-0.3 m / s , the angle between the scraper and the horizontal line is 45°-60°.

Embodiment 3

[0020] The manufacture method of the nanoparticle membrane switch described in embodiment 1, the polyester screen plate is fixed on the screen printing machine, and the conductive silver paste is printed on the ZnO nanoparticle film with a thickness of 0.075 mm by corona treatment by a scraper , and then placed in an oven at 100°C to cure for 30 minutes; after the conductive silver paste layer is cured, use a polyester screen to print a layer of light-curable insulating ink on the non-contact silver paste line, and pass through the ultraviolet light channel of the UV exposure machine to complete Curing; print 19 on the conductive silver paste circuit connected externally and brush a layer of conductive carbon paste; use a laser cutter or mold to cut the ZnO nanoparticle film according to the shape of the membrane switch, and the middle layer of 0.1 mm thick ZnO nanoparticle film in the corresponding The part where the upper and lower points touch is also cut off; finally, the u...

Abstract

The invention discloses a method for manufacturing a nanoparticle thin-film switch. A polyester silk screen printing plate is fixed on a silk screen printing machine, conductive silver paste is printed on the ZnO nanoparticle thin film which is 0.075 mm thick and subjected to corona treatment through a scraper blade, and then the ZnO nanoparticle thin film is placed in an oven at the temperature of 80-120 DEG C to be cured for 25-35 min; after the conductive silver paste layer is cured, a polyester screen printing plate is selected to print a layer of light-cured insulating ink on a silver paste circuit which does not need to be contacted, and curing is completed through an ultraviolet light channel of a UV exposure machine; a layer of conductive carbon paste is printed on the externally connected conductive silver paste circuit; the ZnO nanoparticle thin film is cut according to the shape of the thin film switch by using a laser cutting machine or a mold, and the contact part of the ZnO nanoparticle thin film with the thickness of 0.1 mm in the middle layer at the corresponding upper and lower points is cut off; and finally, the upper-layer thin film, the middle-layer thin film and the lower-layer thin film are assembled and laminated by using waterproof mucilage glue. The method is used for manufacturing the nanoparticle thin film switch.

Description
