Embodiment Construction

[0024] The invention discloses a manufacturing method of a button, which is suitable for portable electronic devices such as mobile phones and PDAs. In this embodiment, a button assembly applied to a mobile phone is taken as an example for illustration.

[0025] see Figure 1 to Figure 3 , the manufacturing method of the button of preferred embodiment of the present invention comprises the following steps:

[0026] Injection molding a button substrate 10 . The key substrate 10 includes a plurality of key bases 20 and a mesh connecting portion 30 connecting the plurality of key bases 20 together. The injection molded material is a transparent plastic such as polycarbonate. The button base 21 includes a top surface 211 and a bottom surface 213 opposite to the top surface 211 . The top surface 211 refers to the surface on which the button is pressed and operated after it is assembled in the portable electronic device.

[0027] A transparent primer is sprayed or printed on the...

Abstract

The invention provides a key manufacturing method. The method comprises the following steps: injection molding is carried out on a key substrate, wherein the key substrate comprises multiple transparent key basic bodies; and each key basic body comprises a top surface and a bottom surface opposite to the top surface; a transparent primer layer is formed on the top surface of the key substrate; a shading metal layer is formed on the primer layer; a semi-transparent color layer is formed on the metal layer, wherein the color layer has the needed color; a transparent protection layer is formed on the color layer; the key basic bodies are punched from the key substrate to obtain multiple keys; the keys and other components are assembled into a keyboard; and laser is used for carving the metal layer through the multiple key basic bodies and the primer layers so as to enable hollow character parts to be formed on the metal layers. The invention also provides a key manufactured by using the above method.

Description

technical field [0001] The invention relates to a method for making a button and a button made by the method. Background technique [0002] Buttons are an important part of portable electronic devices such as cell phones. A kind of existing key production process of portable electronic device is to use plastic injection molding to form a frame-shaped base material connected together with a plurality of key bases, print or spray ink on the base material surface to form a primer layer, and then print or print on the primer. Spray ink to form the appearance ink layer, then laser engrave the top of each key base to hollow out the appearance ink layer to form the character part, and then print or spray ink on the appearance ink layer to form a protective ink layer to protect the appearance ink layer and the exposed bottom paint layer. Then, the button base material that connects the above-mentioned plurality of button substrates is stamped into a single button substrate by punc...
