Abstract

The present invention discloses a method to manufacture a keycap for keys of a keyboard, including: providing a top fabric layer and a molding film disposed beneath the top fabric layer; molding the molding film and the top fabric layer to form a film structure having an inner surface; and providing a keycap body having an upper surface, wherein the outline of the upper surface matches with that of the inner surface to form the keycap. In the present invention, the keycap is formed using the film structure and the keycap body by plastic injection or adhesion agent, the keycap is further manufactured as keys, and a symbol is engraved on the upper surface of the film structure by laser. Because the backlit device's light transmits through the keycap, users can recognize the symbols on the keys.
