  • Patent number: 11973261
    Abstract: An antenna structure with wide radiation bandwidth in a reduced physical space includes a metallic housing, a first feed portion, and a second feed portion. The metallic housing includes a metallic side frame and a metallic back board. The metallic side frame defines a slot, and first and second gaps. The metallic side frame between the first gap and one end of the slot forms a first radiation portion. The second gap divides the first radiation portion into first and second radiation sections. The first feed portion feeds current and signal to the first radiation section, and the first radiation section works in a GPS mode and a WIFI 2.4 GHz mode. The second feed portion feeds current and signal to the second radiation section, and the second radiation section works in a WIFI 5 GHz mode.

  • Patent number: 10475974
    Abstract: A carrier leadframe, including a frame body and a carrier, is provided. The frame body includes at least one supporting portion, and the carrier includes a shell and at least one electrode portion and is mechanically engaged with the frame body via the supporting portion. A method for manufacturing the carrier leadframe as described above, as well as a light emitting device made from the carrier leadframe and a method for manufacturing the device, are also provided. The carrier leadframe has carriers that are separate in advance and mechanically engaged with the frame body, thereby facilitating the quick release of material after encapsulation. Besides, in the carrier leadframe as provided, each carrier is electrically isolated from another carrier, so the electric measurement can be performed before the release of material. Therefore, the speed and yield of production of the light emitting device made from the carrier leadframe is improved.

  • Publication number: 20190027665
    Abstract: A light emitting device may comprise a wing portion of an electrode exposed from the resin housing. The wing portion may be made by a single or multiple stamp cutting process. To increase the connecting region between the electrode and solder, the outer side surface of the wing portion is an uneven surface. The device may further comprise a protective plating layer and an external protective plating layer. The protective plating layer may be coated on the top surface, bottom surface and a portion of the side surface of the electrode. The external portative plating layer would be coated on the outer surface of the wing region. The light reflection of the device from top surface of the electrode portion can be maintained and the outer side surface of wing portion can be protected for improving the reliability of connection between light emitting device and outer substrate.
