Abstract: A process for forming an interface (106) between a plated and a non-plated area (102, 104) on the surface of a plastic component (100) is disclosed. First, an anti-plating layer (110) is formed over the surface of the plastic component. Thereafter, a low-power laser beam (10) is used to remove a portion of the anti-plating layer and to form an interface between the plated area and the non-plated area. A seeding layer (120) is formed on the plated area so that the plated area is electrically conductive. Finally, a metallic layer (130) is electrically plated over the seeding layer. The metallic layer connects with the anti-plating layer via the interface. The cost of producing the anti-plating layer is low. Moreover, since the laser etching operation is able to produce a high-quality interface boundary between the plated and the non-plated area, yield of the process is improved.

The second screw is used to penetrate through the extra battery unit and firmly tighten on the first screw. As a result, the extra battery unit is affixed to the back cover.

Abstract: A recharge apparatus for holding the rechargeable device and battery includes the cradle top and the cradle base. The cradle top includes the elastic gate, the battery-fixing clip, and the charge area. The elastic gate is an opening for inserting the rechargeable battery, and capable of rebounding against pressure so that the elastic gate does not clip the user's finger during operation, and also enhances the appearance as well as being dust-proof. The battery-fixing clip is used for clipping the rechargeable battery tightly. The charge area is an inserting area for charging the rechargeable devices, and has a stand pin to hold the rechargeable devices steadily by inserting the stand pin into the bottom of the rechargeable device. The cradle base assembled with the cradle top includes the elastic joint and recharge PCB (printed circuit board). One end of the elastic joint is designed as the upward curve to touch the rechargeable battery.

Abstract: A structure for a handheld device with a function of electrostatic discharge (ESD) protection has a circuit member (230), a displaying member (240), and a conductive supporting frame (250) with a hollow region (251). The circuit member and the displaying member are affixed to the conductive supporting frame at the hollow region to construct a subassembly (300). The subassembly is then mounted in a housing (202) consisting of upper and lower housings (210,212) at a location that the conductive supporting frame is just beside a gap (203) between the upper and lower housings. ESD-sensitive components (231,232) on the circuit member and the displaying member are surrounded by the conductive supporting frame, whereby ESD entering the housing via the gap which may cause a harm to the ESD-sensitive components and the displaying member is absorbed by the supporting frame and transmitted to ground via an electrical connection between the supporting frame and ground trace of the circuit member.
