Abstract:
The method of surface mounting radio frequency components includes using at least one radio frequency component (300, 810, 850) having a pair of input/output contact points (330, 332, 830, 832, 870, 872) or areas at corners on the underside of the component, wherein each of the input/output contact points or areas abuts the adjoining edges of the corners. The component is positioned relative to a pair of traces (846, 856, 858, 860) on a circuit for enabling an electrical connection thereto in a range of angular dispositions. By using a single non-customized component, adjacent components can be configured with a signal flow path of a range between about 0 degree (a chain configuration) and about 180 degrees (a "U" turn).

Abstract:
An electronic component includes an insulating surrounding member surrounding the electronic element while allowing a first surface of the electronic element to be exposed from a second surface of the surrounding member. A wiring board faces a third surface comprising the first and second surfaces. An insulating joining member is interposed between the third surface and the wiring board and joins the third surface and the wiring board together. A conductive bump, located between the third surface and the wiring board, electrically connects the electronic element and the wiring board. The joining member has a first through hole that overlaps a vibration region in the first surface in perspective plan view. The joining member has a second through hole that accommodates the bump. At least a portion of at least one of the first through hole or the second through hole overlaps the second surface in perspective plan view.
Abstract:
A method of manufacturing an electronic device includes preparing an electronic component including a first substrate on a main surface of which a functional unit and a first resin layer are formed. The first resin layer has a first surface facing the main surface of the first substrate, a second surface opposed to the first surface, a cavity on the first surface enclosing the functional unit, and a portion defining a wall of the cavity. The first resin layer defines a recess provided with a solder layer on the second surface. The method further includes preparing a second substrate having an electrode pad formed on a main surface, aligning the electronic component with the second substrate to layer the solder layer and the electrode pad in contact with the solder layer, and forming the electronic component and the second substrate into the electronic device.

Abstract:
An electronic component may include a substrate having a functional unit formed on a main surface of the substrate and a first resin layer formed on the main surface, the first resin layer having a first surface facing the main surface and a second surface opposed to the first surface, the first resin layer defining a cavity on the first surface enclosing the functional unit, the first resin layer defining a recess on the second surface, and a solder layer being formed in the recess so as not to exceed the second surface in a thickness direction. The functional unit may include a surface acoustic wave (SAW) element or a film bulk acoustic resonator (FBAR) having a mechanically movable portion. The substrate may be formed of dielectric material.
