Abstract:
A multilayer microelectronic circuit to be directly mounted on a substrate and to be used, for example, as a resonator. The multilayer microelectronic circuit comprises a plurality of dielectric layers and patterned electrodes which are laminated one upon another to form a laminated structure, the dielectric layers and the patterned electrodes forming an electrical circuit. The laminated structure has side surfaces extending along a direction in which the dielectric layers and the patterned electrodes are laminated. An input line is formed at one of the side surfaces and connected with an input section of the electrical circuit. An output line is formed at one of the side surfaces and connected with an output section of the electrical circuit. A grounding line is formed at one of the side surfaces and connected with a grounding section of the electrical circuit. Additionally, a signal line formed at one of the side surfaces, for connecting sections of the electrical circuit. The signal line has an end positioned adjacent a mounting surface at which the multilayer microelectronic circuit is directly mounted on the substrate, in which the end of the signal line is separate from the mounting surface so as to be insulated from electrical contact with the substrate.
Abstract:
An oscillator assembly includes an oscillator circuit that is configured to generate a frequency signal. A temperature compensation circuit is in communication with the oscillator circuit and adapted to adjust the frequency signal in response to changes in temperature. The oscillator and temperature compensation circuits are located within an oven. A heater and a temperature sensor in communication with the heater are also both located in the oven. The temperature sensor is adapted to directly control the heater in response to changes in temperature. In one embodiment, the oscillator components are mounted to a ball grid array substrate which, in turn, is mounted on a printed circuit board. In this embodiment, a resonator overlies the ball grid array substrate and a lid covers and defines an oven and enclosure for the resonator and the ball grid array substrate. The oscillator and temperature compensation circuit are defined on the ball grid array substrate.
Abstract:
A method for affixing a resonator to a printer circuit board is provided. The method uses a thin metal film which may be affixed to a surface of a stand off, or directly to a surface of a resonator. The metalized surface may be affixed to a printer circuit board using a molten agent with a surface tension which withstands the downward force exerted by the puck's weight. The metalized surface may be affixed to a printed circuit board using a solder paste and the solder is allowed to reflow. The surface tension of the molten solder causes the resonator (or resonator puck) to self-center, ensuring proper placement and eliminating the need for repositioning. Since the resonator is not positioned using traditional glues which are subject to shifting during transportation or curing, then the resonator is not subject to shifting, eliminating the need to reposition the resonator after the resonator become fixed.

A surface mounting package includes a metal base (1) with a lower surface having a through hole, a metal lead (2) arranged to be inserted into the through hole, an insulating material (3) filling in an internal space defined by the metal base (1), a cap (30) covering the metal base (1) as a lid, and an electronic part component arranged at a surface (2i) on the internal space side of the metal lead (2). The internal space is held at an air-tight atmosphere. The metal base (1) has a lower surface positioned on the same plane as a lower surface of the metal lead (2) or the insulating material (3), the same plane (P) forming a plane to be attached to a mounting board.

Abstract:
A base of a surface-mount electronic component package holds an electronic component element and is to be mounted on a circuit board with a conductive bonding material. The base has a principal surface and an external connection terminal to be electrically connected to the circuit board. The external connection terminal is formed in the principal surface. The base includes a bump formed on the external connection terminal. The bump is smaller than the external connection terminal. The base has a distance d between an outer periphery end edge of the external connection terminal and an outer periphery end edge of the bump along an attenuating direction of stress on the external connection terminal. The stress is generated in association of mounting of the base on the circuit board. The distance d is more than 0.00 mm and equal to or less than 0.45 mm.
