According to one embodiment, a flexible printed circuit has a first circuit substrate and a second circuit substrate extending over the first circuit substrate. The first circuit substrate has a connector area. The second circuit substrate has an opening and an adhesive layer. The opening allows the connector area to be exposed. The opening has an opening edge which has a predetermined shape and defines the opening. The second circuit substrate has in the opening a depressed portion depressed deeper than the opening edge. Among various constituents of the second circuit substrate, at least the adhesive layer is depressed from the opening edge at the depressed portion.

Flexibile printed circuit and electronic device

According to one embodiment, an electronic apparatus includes a housing, a connector, and a component connected to the connector. The component includes a first and third electrically conductive portion on a first surface, a second electrically conductive portion on a second surface, and a first and second cover portions. The second electrically conductive portion is connected to the first electrically conductive portion. The third electrically conductive portion is kept in contact with a terminal of the connector, and connected to the second electrically conductive portion. The first and second cover portions cover at least a part of the first and second electrically conductive portion.

Television and electronic apparatus

A flexible printed circuit board includes: a base film that has electrical insulation property; a conductive pattern that is formed on the base film and including a pair of differential signal lines and a ground line; an insulating layer that is formed on the conductive pattern; a conductive layer that is formed on the insulating layer; and a connecting portion that electrically connects the ground line and the conductive layer through a penetration hole formed on the insulating layer.

Flexible printed circuit board and electronic apparatus

According to one embodiment, an electronic apparatus includes a housing, a circuit board accommodated in the hosing and including a first surface and a second surface located on an opposite side to the first surface, a flexible printed wiring board having an elasticity, electrically connected to the circuit board and provided from the first surface of the circuit board over to the second surface, and a pressing portion formed from a part of the flexible printed wiring board as it is bent, and pressing the flexible printed wiring board towards the first surface as it is brought into contact with the inner surface of the housing, which opposes the first surface of the circuit board.

Electronic apparatus and flexible printed wiring board

According to one embodiment, a printed wiring board includes an insulating layer, a first conductor pattern on the insulating layer configured to be a signal line, and a second conductor pattern on the insulating layer. The second conductor pattern includes a larger conductor area than the first conductor pattern, and a slit which allows the second conductor pattern to stretch to follow a thermal expansion of the insulating layer.

Printed wiring board and electronic apparatus

A wiring board is constructed such that a base layer constituted of photosensitive polyimide, a conductor layer constituted of copper, and a cover layer constituted of photosensitive polyimide are formed in this order on a stainless layer. On an electronic part mounting portion, a plurality of lands are formed so as to correspond to electrode terminals of an electronic part to be mounted. On the periphery of the electronic part mounting portion, an underfill diffusion preventing portion formed by removing the cover layer in a trench shape is provided so as to surround the periphery thereof.
