Abstract: In an embodiment, an interposer has a first side, a first integrated circuit device attached to the first side of the interposer with a first set of conductive connectors, each of the first set of conductive connectors having a first height, a first die package attached to the first side of the interposer with a second set of conductive connectors, the second set of conductive connectors including a first conductive connector and a second conductive connector, the first conductive connector having a second height, the second conductive connector having a third height, the third height being different than the second height, a first dummy conductive connector being between the first side of the interposer and the first die package, an underfill disposed beneath the first integrated circuit device and the first die package, and an encapsulant disposed around the first integrated circuit device and the first die package.

Abstract: A package substrate is provided and includes a core board body and a first circuit structure and a second circuit structure disposed on opposite sides of the core board body, where the number of wiring layers of the second circuit structure is different from the number of wiring layers of the first circuit structure, so that the package substrate is asymmetrical. The first circuit structure and the second circuit structure are designed according to the thickness and coefficient of thermal expansion of the first dielectric layer of the first circuit structure and the second dielectric layer of the second circuit structure, so as to prevent the problem of warping from occurring to the package substrate.

Abstract: A system and a method for a secure trading mechanism combining wireless communication and wired communication are proposed, which, in the condition of two-way trading constructed based on network connection of a wireless communication device functioning in two-way transmission to a trading server and a trading host of a wired communication devices, allow the trading to be performed in real time and the correctness to be determined for data transmitted between different levels of the network according to a secure communication protocol defined in each communication device, so as to assure the security of trading data in transmission, and prevent the trading data from being acquired or changed without authorization.

Abstract: The convention transmission method is an on-demand data communication, in which one discloses a demand and one provides a supply. However, this communication way is not suitable nowadays. Since amount of current data transmission is very large. In order to improve the quality in service, the service provider provides actively the required service to the customer. After browsing by the customer, then the customer transfers the selection items to the service provider and then the service provider provides required service to the customers, By this way, the customer may browse products rapidly and the quality of information service is improved.
