Film keyboard making method and its structure

Abstract

The invention provides a manufacturing method and a structure for a thin keyboard with a seamless panel surface. The method is as follows: printing inks of different colors are printed on a surface of a hard base material, so as to form light-penetrable patterns in panel-shapes, including numbers, characters, symbols, non-button type, dial and end, and a plurality of grooves are formed on the panel through die cut by a machine; and then printing inks with different colors are printed on a surface of a soft base material, so as to form internal lining flakes of a light shading layer and a reflecting layer corresponding to the panel patterns; the panel and the internal lining flakes are arranged into a die, the rubber is filled in the die, and after hotpressing, the rubber is glued to the bottom parts of the internal lining flakes for forming a light guiding layer; meanwhile, the light shading layer, the reflecting layer and the rubber are simultaneously extruded onto the surface of the panel, forming the seamlessness between keys on the panel surface; finally, the light guiding layer is dotted by the laser, which ensures that the light guiding layer is provided with light guiding particles of the spotlighting effect.

Description

technical field [0001] The invention relates to a keyboard structure, in particular to a method for manufacturing a thinner keyboard structure. Background technique [0002] With the continuous improvement of communication technology, many electronic products are manufactured towards light, thin, short, and small volumes. Therefore, the size and weight of electronic products are reduced, so that users can carry them easily. In order to reduce the size and weight of the electronic product, in addition to reducing the size of the internal integrated circuit, the area and thickness of the keyboard of the operation interface on the surface of the electronic product must be relatively reduced before it can be installed on the communication device. [0003] The traditional keyboard structure, such as the invention patent of US No. US 7070349 B2 "thin keyboard and components of electronic equipment and its manufacturing method", as shown in Figure 16, what this patent discloses is ...

Problems solved by technology

Although the gap E between the display body C and the button body D is narrowed, foreign matter will still be stuck in the gap after a long time of use, and even water will seep into the interior of the electronic product, resulting in poor contact of the circuit board and corrosion damage of components
