Abstract
Disclosed is a method for manufacturing a keypad of a portable terminal, in which a metal thin layer (62) deposited on a base film (61) is easily and finely patterned to form fonts (62a) having a three-dimensional pattern, and key top-shaped grooves (61a) are formed in a metal laminate thin film (60) and filled with injecting molded matter (70).
Claims5
A method for manufacturing a keypad of a portable terminal, having keys and a pad, comprising:
- preparing a metal laminate thin film obtained by coating a base film with a metal thin layer;
- patterning the metal thin layer, to form fonts;
- locating the metal laminate thin film on a lower mold having key top-shaped grooves formed therein and pressing the metal laminate thin film by a first upper mold having key top-shaped protrusions formed thereon, to form key top-shaped grooves in the metal laminate thin film;
- and
- filling the key top-shaped grooves with injecting molded matter made of synthetic resin and pressing the matter by a second upper mold, to form an integrated key assembly having the keys, each provided with a key top-shaped injecting molded matter.
