Preparation method for metal keystroke panel with multi-group micropores

Abstract

The invention provides a preparation method for a metal keystroke panel with multi-group micropores, comprising the steps as follows: firstly, a metal sheet is provided and etched so that multi-group micropores are formed on the metal sheet; filling material is coated on the surface of the metal sheet and seeped in the micropores; subsequently, the metal sheet is die-cut so as to form a metal keystroke panel with specific shapes; subsequently, the metal keystroke panel is arranged in a die where plastic material is injected subsequently; one side surface of the metal keystroke panel forms a grain layer; subsequently, the other side surface of the metal keystroke panel is coated by a backlight module which is provided with a plurality of patterns, the shape of which is formed by the arrangement of a plurality of light-guide micro-structures; finally one side surface of the backlight module is coated by a circuit module, thus completing the preparation of the metal keystroke panel.

Description

technical field [0001] The invention relates to a button panel of an electronic device, in particular to a method for manufacturing a metal button panel. Background technique [0002] With the continuous improvement of communication technology, many electronic products are manufactured towards light, thin, short, and small volumes, so as to reduce the size and weight of electronic products, 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 on the surface of the electronic product must also be relatively reduced before it can be installed on the communication device. [0003] A traditional metal key panel, such as the metal key panel 10a disclosed in US Patent Application No. US2007 / 0205986A1 (see FIG. 1(a), (b)), has an elastic layer 1a, and there are multiple protrusions on one side of the elastic layer 1a 11a, and...

AI Technical Summary

Problems solved by technology

However, the hollow parts 21a on the metal buttons 2a must be filled into the resin layer 22a one by one, and then the metal buttons 2a must be accurately pasted on one side of the elastic layer 1a one by one, resulting in more time-consuming and labor-intensive manufacturing. work, and not easy to make

After the metal key panel 10a is combined, when it is combined with the base body 20a, a gap is formed between the periphery of the metal key 2a and the base body 20a, and the gap is easy to allow external dust to accumulate or water to infiltrate, causing the key to not be pressed smoothly or causing internal damage. circuit short circuit

In addition, there is no reflective effect of texture and luster on one side of the metal key panel 10a, which makes the overall appearance of the metal key panel 10a too dull visually.
