Abstract: A fan-out semiconductor device includes stacked semiconductor dies having die bond pads arranged in columns exposed at a sidewall of the stacked semiconductor dies. The stacked dies are encapsulated in a photo imageable dielectric (PID) material, which is developed to form through-hole cavities that expose the columns of bond pads of each die at the sidewall. The through-hole cavities are plated or filled with an electrical conductor to form conductive through-holes coupling die bond pads within the columns to each other.

Abstract: An antenna module includes first to third radiators and a ground radiator. The first radiator includes first and second sections and excites at a first frequency band. An extension direction of the first section, including a feeding end, is not parallel to an extension direction of the second section. The second radiator includes third and fourth sections. The third section extends from an intersection of the first and second sections. The third section excites at a second frequency band. The third radiator is disposed beside the first radiator and away from the second radiator. The ground radiator is disposed on one side of the first, second, and third radiators, and includes a ground end. The fourth section of the second radiator is connected to the third section and the ground radiator. The third radiator is connected to the ground end.

Abstract: A super wide bandwidth coupling antenna comprises a first radiation portion made of electric conductor; the first radiation having a body and a feeding frame extending from a body of the first radiation portion; a second radiation portion formed by an electric conductor; a supporting frame extending from a body of the second radiation portion; a ground portion made of electric conductor; one end of the ground portion being connected to the supporting frame of the second radiation portion; a signal feeding wire having a main signal end wire which is electrically connected to the feeding frame of the first radiation portion; a ground end wire of the signal feeding wire being electrically connected to the ground portion; an isolation post for positioning the first radiation portion and second radiation portion with an insulating gap between the first radiation portion and second radiation portion.

Abstract: A hydrodynamic bearing assembly (10) which includes a bearing sleeve (11) defining a receiving chamber (112) therein; a bearing (15) received in the receiving chamber of the bearing sleeve; a shaft (17) rotatably disposed in the bearing; first and second lubricant retaining spaces (142, 164) disposed at ends of the bearing respectively for receiving lubricant therein; and a plurality of first and second lubricant generating grooves (171, 172) disposed in the first and second lubricant retaining spaces respectively, for guiding the lubricant at the first and second lubricant retaining spaces toward a middle portion of the shaft to generate lubricant pressure on the shaft against the bearing.

Abstract: An electromagnetic interference diminishing structure of a connector assembly. The connector assembly includes a socket and a plug. The socket includes a main body enclosed by a metal housing connected to the grounding circuit of a circuit board. The plug includes a shield metal housing formed with grounding sections. A terminal main body is inserted in the shield metal housing. An insulating housing is fitted around the shield metal housing. When a front section of the plug is plugged into the socket, the metal housing of the socket and the grounding sections of the shield metal housing of the plug contact with each other through the holes of the insulating housing of the plug. Accordingly, the electromagnetic interference can be effectively diminished.
