An information broadcasting and interaction system includes: a control device; a Bluetooth smart network connected with the control device, including a plurality of node devices and sense devices, and configured to operate in a mesh mode, a beacon mode, or a deep sleep mode; and a plurality of user devices connected with the Bluetooth smart network. Each node device is configured to relay control and broadcast information or feedback information between the control device and any specific device in the Bluetooth smart network, and to broadcast customized information to the user devices in a predetermined range. Each sense device is configured to collect data with a sensor integrated with the device, and relay the data to the control device.

Information broadcasting and interaction system

A system for bonding a die to a high power dielectric carrier such as a ceramic dielectric core with double-sided conductive layers is described. In the system, the upper conductive layer has a first area whose surface has a first wettability. A second area that at least partially surrounds the first area has a surface with a second wettability that is greater than the first wettability. During bonding, an adhesive material bonding a chip to the substrate spreads among the first area by a downward force placed on the chip. Due to the difference in wettability, the adhesive material then spreads among the second area by a wetting force generated by the greater second wettability of the second area surface causing the chip to be drawn down until reaching a predetermined position. The predetermined position can be determined by substrate protrusions or substrate cavities.

High power dielectric carrier with accurate die attach layer

The presently claimed invention is to provide a package for compact RF signal system, and a method to form the package thereof in order to miniaturize the size of package, improve signal integrity, and reduce manufacturing cost. The package comprises a hybrid substrate with a sandwiched structure, in which the hybrid substrate comprises an upper layer and a lower layer with different dielectric properties being separated by an interposer for improving electrical isolation and mechanical stiffness. Metal layers are formed on the sidewalls of the opening to surround an active component, such that the metal sidewalls together with two ground plates in the upper and lower layers constitute a self-shielding enclosure inside the package to protect the active component.
