Abstract: In accordance with some embodiments, a package-on-package (PoP) structure includes a first semiconductor package having a first side and a second side opposing the first side, a second semiconductor package having a first side and a second side opposing the first side, and a plurality of inter-package connector coupled between the first side of the first semiconductor package and the first side of the second semiconductor package. The PoP structure further includes a first molding material on the second side of the first semiconductor package. The second side of the second semiconductor package is substantially free of the first molding material.

Abstract: A keyboard comprising a top case and a bottom case comprised of a transparent material and including: a plurality of recesses each configured to receive one of a plurality of light emitting diodes (LED); a plurality of cavities that extend linearly and radially from a middle portion of the bottom case toward an outer edge of the keyboard, where light emitted by the LEDs is directed radially towards and out of the outer edge of the keyboard, due in part to the emission pattern of the corresponding LED and by adjacent cavities of the plurality of cavities; and a plurality of screw bosses configured to receive screws that securedly couple the top case to the bottom case, wherein the bottom case is coupled to the top case forming an outer housing for the keyboard.

Abstract: A fastening structure for a portable electronic device includes a main housing and a frame. The main housing defines a slot. A protrusion and a block are formed at two opposite sides of the slot. The frame includes a tab. The tab defines a locking hole. The block pushes the tab toward the protrusion to allow the protrusion to be latched in the locking hole for connecting the frame to the main housing.

Abstract: An elastic sheet structure includes an elastic body and a conductive body. The elastic body is capable of elastic deformation, and the conductive body includes a main body, a first elastic arm, and a second elastic arm. The main body is installed into the elastic body; the first elastic arm and the second elastic arm are connected at opposite sides of the main body and extend out from two opposite ends of the elastic body. The first elastic arm is capable of electrically connecting to ground to conduct away static electricity through the second elastic arm, the main body, and the first elastic arm. An electronic device employing the elastic sheet structure is also described.
