The mechanical arm is electronically coupled to the engraving controller and controlled by the engraving controller. The laser is electronically coupled to the engraving controller and controlled by the engraving controller in such a manner that the laser engraves an unegraved workpiece according to the at least one two-dimensional pattern.

Abstract: A surface treatment process for a metal article includes the following steps. Firstly, a metal article, made of at least one of copper and an alloy thereof, is provided. Secondly, a surface of the metal article is degreased. Thirdly, the surface of the metal article is activated in an acid solution. Finally, the surface of the metal article is deactivated by submersion in an antioxidant agent.

Abstract: A positioning pin (40) is provided. The positioning pin includes a positioning shaft (42) and a flange (41). The flange is formed on one end of the positioning shaft. The positioning portion is formed on the other end of the positioning shaft.

Abstract: A housing (100) for an electronic device includes an opaque base (10). The base has a plurality of blind holes (120) and a number of through holes (140) defined therein. Each through hole communicates with a corresponding blind hole. The through holes are arrayed in a determined pattern.

Abstract: A keypad assembly (15) applied to a portable electronic device and mounted in a shell of the portable electronic device is provided. The keypad assembly comprises a keypad cover (151) and a printed circuit board (152). The keypad cover is provided with at least one contact portion (1516) thereon. The printed circuit board provided with a plurality of signal-sensing portions (1522) thereon. The shell is provided with at least one guide hole (116) corresponding to the plurality of signal-sensing portions. The shell is configured between the keypad cover and the printed circuit board, and the keypad cover is rotatably mounted in the shell. The signal-sensing portion is pressed by the contact portion through the guide hole. A portable electronic device using the keypad assembly is also disclosed.

Abstract: A keypad assembly (10) for use in a portable electronic device (8), includes a housing (14) and a key (12). The housing is substantially a flat board, and defines a recess and a hole (143, 145) therein. The key is mounted in the recess and the hole and is defined as in an original state when it is not operated. The key is capable of moving in different directions relative to the housing when it is manually operated. The key is defined as in an operational state when it is manually moved.

Abstract: A view panel (10) for an electronic device includes a substrate (11) and a paint layer (12). The substrate is made of a transparent material.
