Abstract: A method for bonding a plastic member onto a metal housing is provided. A metal housing having an inner surface and an outer surface is prepared. The inner surface of the metal housing is subjected to physical processing to thereby form a bonding area. An adhesive layer is formed on the bonding area. A plastic mold member is formed on the adhesive layer by plastic injection molding.

Abstract: A method for bonding a plastic member onto a metal housing is provided. A metal housing having an inner surface and an outer surface is prepared. A hollow-carved area is provided on the metal housing. The inner surface of the metal housing is subjected to physical process, thereby forming a bonding area. An adhesive layer is formed on the bonding area. A plastic mold member is formed on the adhesive layer by performing a first plastic injection molding. An optical plastic member is molded on the hollow-carved area by performing a second plastic injection molding.

Abstract: A mechanical keypad with touch panel function includes a key set including a plurality of keycaps and a keytop covering the keycaps, a backlight layer under the key set, a capacitive touch unit selectively disposed under several keycaps, an elastic layer including an elastomer and a plunger corresponding to the keycaps and disposed under the capacitive touch unit as well as a circuit board including metal domes and dome sheets corresponding to the keycaps. Each metal dome provides a mechanical feedback force so that the keycaps are able to be in indirect contact with the metal domes and the dome sheets by means of the plunger.

Abstract: A metal plate press-forming process with a fine line pattern, in which the metal plate is heated and applied with a gas or liquid pressure in several stages so as to be pressed against a molding die to be formed into a shape and simultaneously to obtain a second fine-line pattern transferred from a first fine-line pattern on the molding die. A press-formed metal housing obtained using the aforesaid metal plate press-forming process is also disclosed. Also, a method of forming a fine line pattern on a molding die is disclosed, in which a patterned photoresist layer is formed on a block, and a fine line pattern on the block is formed by etching the block using the patterned photoresist layer as a mask.
