摘要:
A semiconductor device has a die support and external leads formed integrally from a single sheet of electrically conductive material. A die mounting substrate is mounted on the die support, with bonding pads coupled to respective external connection pads on an external connector side of the substrate. A die is attached to the die mounting substrate with die connection pads. Bond wires selectively electrically couple the die connection pads to the external leads and the bonding pads and electrically conductive external protrusions are mounted to the external connection pads. An encapsulant covers the die and bond wires. The external protrusions are located at a central region of a surface mounting side of the package and the external leads project outwardly from locations near the die support towards peripheral edges of the package.

A three dimensional (3D) package includes a helix substrate having a columnar part including a top surface, a bottom surface and a sidewall, and a plurality of steps arranged along the sidewall of the columnar part in the form of a helix. Semiconductor integrated circuits (dies) may be attached on supporting surfaces of the steps. The columnar part, the steps and the dies can be covered with a mold compound. I/Os are formed at either the sides of the steps and/or the top and/or bottom of the columnar part.

摘要:
A composition used for high-strength impermeable concrete. The composition contains sand, stone, cement, water reducer, water and reinforced impermeable sand. The reinforced impermeable sand includes aeolian sand and binder covering the surface of the aeolian sand. The reinforced impermeable sand can fill the gap between the sand and the stone, and well combine various components in the composition, and suppress the seepage phenomenon of the molded concrete, thereby greatly improving the strength and impermeability of the concrete.

Embodiments of the present invention provide a method, a server, and a system for implementing a video-based value-added service. The method includes: acquiring, by an event server, association event data which corresponds to a video currently played by a first client; when detecting an event trigger condition, generating, by the event server, an event notification according to the association event data, and sending the event notification to an application server; forming, by the application server, value-added service content according to preset value-added service data and event data in the event notification, and providing the value-added service content for a second client.
摘要:
A method, apparatus and system for obtaining user information are disclosed by the present invention. The present invention solves the problem of lower security of user information. The method includes: obtaining the interactive state of the service requester in the service request process, wherein the interactive state is used for indicating the specific state in which the service requester and its service are during the process of interaction with each other; determining if the interactive state of the service requester, in the process of requesting the service, meets the preset access-authorized-policy of the user information in the service request; when the interactive state of the service requester, in the process of requesting the service, meets the preset access-authorized-policy of the user information in said service request, obtaining the user information and sending the user information to the service.
