Abstract: A package includes a frontside redistribution layer (RDL) structure, a semiconductor die on the frontside RDL structure, and a backside RDL structure on the semiconductor die including a first RDL, and a backside connector extending from a distal side of the first RDL and including a tapered portion having a width that decreases in a direction away from the first RDL, wherein the tapered portion includes a contact surface at an end of the tapered portion. A method of forming the package may include forming the backside redistribution layer (RDL) structure, attaching a semiconductor die to the backside RDL structure, forming an encapsulation layer around the semiconductor die on the backside RDL structure, and forming a frontside RDL structure on the semiconductor die and the encapsulation layer.

Abstract: The present invention relates to an improve structure for a wheel frame with a supporting member, which sets up a supporting member with geometry shaped between each spoke. The supporting member is installed around the outer edge of the hub. One end of the respective spokes is positioned on the supporting member, and the other end is positioned on the rim. Thereby, the supporting intensity of the supporting member can be increased so as to avoid being deformed, and the wind resistance can be reduced when the bicycle is ridden.

Abstract: A spoke-assembling structure for a bicycle wheel comprises a hub, a plurality of sets of spokes and a wheel. In the wheel being formed a plurality of apertures for anchoring an end of the spokes. The spokes are connected between the wheel and the hub. In the wheel are additionally formed a plurality of assistant apertures for anchoring a plurality of assistant spokes, both end of the assistant spokes are directly anchored on a rim of the wheel, vertical distances from the respective assistant spokes to the hub are the same.

Abstract: A hub for a bicycle comprises a flange formed at either side thereof, in the flanges are annularly formed a plurality of apertures through which a plurality of spokes are inserted and connected to a rim. On an axial surface of the hub is formed at least a positioning portion that is located between the flanges of the hub for securing an end of the spokes, another end of the respective spokes is secured to the rim, so that he spokes between the hub and the rim are tensioned evenly and properly and can be prevented from inappropriate deformation, and accordingly the bicycle can run more safely.
