Embodiment Construction

[0024] Preferred embodiments of the invention will now be described in detail and the accompanying drawings illustrate examples used. The same reference numbers in the drawings indicate the same or similar parts.

[0025] figure 1 To illustrate a flow chart of a method of manufacturing a metallized keyboard according to one embodiment of the present invention, Figure 2a to Figure 2f based on figure 1 Schematic diagram of the fabrication process for fabricating metallized keyboards by the method shown.

[0026] In step S1, Figure 2a The key shown is first formed by an injection molding process.

[0027] The key 2 may be formed of ABS resin or a thermoplastic resin such as polycarbonate (PC) or polymethyl methacrylate (PMMA) that cannot be used in combination with a metal plating process.

[0028] The best method is that the key 2 is formed of a translucent or transparent material, so that the letters or numbers on the key 2 can be displayed brightly under the condition o...

Abstract

A method for manufacturing a metallized keyboard, comprising the steps of: forming a key with a thermoplastic resin material through an injection molding process, forming a conductive layer on the surface of the key, forming a functional mark on the conductive layer, and forming a functional mark on the conductive layer except for the functional mark. A metal layer is formed.

Description

technical field [0001] The present invention relates to a keyboard for a mobile phone and a manufacturing method thereof, and more particularly to a keyboard capable of reliably maintaining the attached state of a metal layer formed to provide a metallic feeling and capable of being manufactured using a variety of metals and a manufacturing method thereof . Background technique [0002] In general, keypads are switch devices used in communication terminals such as mobile phones and personal digital assistants to generate signals or perform various additional functions. The keyboard has a plurality of keys printed with letters or figures, and is mounted on the front case of the terminal in a state capable of generating signals. [0003] In the case of a mobile phone, a dome-shaped switch is pressed on a keypad, elastically deforming it to contact a contact point on a printed circuit board (PCB) and generate a signal, thereby performing various...
