Abstract: A package component and forming method thereof are provided. The package component includes a substrate and a conductive layer. The substrate includes a first surface. The conductive layer is disposed over the first surface. The conductive layer includes a first conductive feature and a second conductive feature. The second conductive feature covers a portion of the first conductive feature. A resistance of the second conductive feature is lower than a resistance of the first conductive feature.

Abstract: A file sharing system includes: a second, first user device and a cloud server. The first user device uploads a file and sharing information corresponding to the file, wherein the sharing information includes file recipient information of an application corresponding to the second user device. The cloud server receives the file and the sharing information, and transmits a first sharing message to the second user device according to the sharing information. The second user device transmits a request message to the cloud server for requesting the file according to the first sharing message. The cloud server authenticates the second user device according to the request message, and transmits a second sharing message to the application corresponding to the second user device according to the file recipient information when the authentication is successful. The second user device accesses the file according to the second sharing information of the application.

Abstract: A data-access system, adapted to a plurality of Cloud storage providers, including a processing module, an access module and a storage module. The processing module receives a file, and obtains a dismantling rule according to file information. The processing module further dismantles the file into a plurality of sub-files according to a storage signal and the dismantling rule. The access module respectively detects the status of the connection of the Cloud storage providers, and the sub-files are stored to at least two of the Cloud storage providers according to the connections statuses. The storage module stores the dismantling rule and the storage records correspond to the sub-files.

Abstract: An data search apparatus includes: a storage unit, storing a plurality of data; an input unit, inputting a data name, selecting a plurality of preference sets, and inputting a grading set by a user; a process unit, receiving the data name for searching for a plurality of candidate data from the data stored in a storage unit and generating a ranking result.
