The second and third printed wiring boards are connected to each other in a state where plate thickness directions thereof are oriented in different directions from each other about a normal line to the part mounting surface. Further, at least one of the second printed wiring board and the third printed wiring board is provided with an antenna pattern.

A circuit board includes a board body including a wiring; a micro-control unit, arranged on the board body; and an inertial measurement unit arranged on the board body and in communication with the micro-control unit via the wiring to transmit inertial measurement data detected by the inertial measurement unit to the micro-control unit, and where the board body includes a main body part and an isolated part located at a peripheral of the main body part, the micro-control unit is supported on the main body part, and the inertial measurement unit is supported on the isolated part.

A PCB direct connector including terminal members configured to have a pair of contact portions elastically contacting an upper surface and a lower surface of the circuit board and be electrically connected to conductive patterns disposed on at least one of the upper surface and the lower surface, and a connector housing configured to accommodate the terminal members therein and allow a connector connection portion formed at one side of an end of the circuit board to be fitted into and released from the connector housing.

A user interface includes a curved outer surface, a generally flat printed circuit board defining a base plane, and a capacitive touch sensor connected to the generally flat printed circuit board and offset from the base plane. The capacitive touch sensor is substantially aligned with the curved outer surface. The user interface may be provided on an appliance.

A membrane circuit board includes a first flexible circuit board, a second flexible circuit board and a nanomaterial layer. The nanomaterial layer includes plural polymeric structures. The nanomaterial layer is formed on the first flexible circuit board, the second flexible circuit board and/or a junction region between the edge of the first flexible circuit board and the second flexible circuit board to prevent at least one of the upper metallic conductor line and the lower metallic conductor line from contacting with a specified chemical element. Consequently, the conductive impedance of the upper metallic conductor line and the lower metallic conductor line is not affected by the specified chemical element. Moreover, the present invention also provides a keyboard device with the membrane circuit board.
