摘要:
In an oscillator circuit employing a pattern coil on a printed-wiring board as a resonator circuit, in order to satisfactorily adjust dispersion in oscillation frequencies, an air-core coil wound by more than half a turn and less than one turn is provided so as to be connected to the pattern coil in parallel and planted on the printed-wiring board, and the oscillation frequency is adjusted by adjusting the angle of the air-core coil relative to the printed-wiring board.

An apparatus such as an appliance with a printed circuit board, PCB, (202) mounted haptic feedback device (200) is provided. The apparatus comprises a printed circuit board (PCB) having an opening (204) defined therein, and a spool (206) affixed to the PCB and having a shaft with a coil (208) wound thereabout. The shaft defines an opening aligned with the opening of the PCB. The apparatus also comprises a spring-loaded plunger positioned and movable within the opening of the shaft. The spring-loaded plunger includes a metallic disk operatively coupled to an end of the plunger and distally positioned to the spool. A control component of the apparatus is configured to energize the coil according to a haptic feedback pattern, and thereby cause the coil to attract the metallic disk and move the plunger within the opening of the shaft of the spool, and through the opening of the PCB.

To provide a circuit board that is capable of establishing electrical connection, that is thinner, and that has a higher maintainability. A circuit board 100 includes a substrate 101 including a hole portion 110 that penetrates the substrate 101 in a plate thickness direction, and a connector region including a first conductor layer 202 that closes one side of the hole portion 110, liquid metal 210 disposed in a recess 201 formed by the hole portion 110 and the first conductor layer 202, and a sealing layer 212 that is the liquid metal 210 cured on a liquid surface side. The liquid metal 210 may be in contact with a second conductor layer 204 formed in the recess 201.
摘要:
An electrical connector has one or more body portions in which is disposed an electrical terminal having at least one contact pad interface for coupling to a contact pad of at least one printed circuit board (PCB). The body has an associated fastening device which is used to mechanically and electrically couple the electrical connector to the at least one PCB. The electrical connector may be provided with a full or partial hourglass-like shape, when viewed from the side and/or from above, to facilitate its use with a PCB that carries a source of light, such as an LED.
