Abstract:
A circuit board device includes a flexible circuit board, a rigid circuit board bonded to at least a part of the flexible circuit board, and a metal plate bonded to at least one of the rigid circuit board and a portion of the flexible circuit board which is itself bonded to the rigid circuit board. Heat generated from components mounted on the rigid circuit board is dissipated through the metal plate to a frame, for example.
Abstract:
A mounting arrangement for an integrated circuit leadless chip carrier (13) for providing compliance to prevent solder joint failures due to stress and differential thermal expansion. A supporting substrate board (10, 20, 30) has bonded to one surface a flexible sheet (11) carrying printed wiring (12) to which the carrier (13) is electrically connected by means of solder pedestals (19). At each of the latter connections the board (10, 20, 30) presents recesses (15, 22, 31a, 33a) over which the sheet (11) is freely suspended to provide free sheet portions (18) which absorb the stress and differential expansion to protect the solder connections.
Abstract:
A device includes a first sealing member, a second sealing member, a first circuit member and a second circuit member. The first sealing member basically includes a first film formed with an opening and includes a frame film. At least one of the first circuit member and the second circuit member includes an exposed portion and a seal portion which surrounds the exposed portion. The frame film has a film-seal portion and a circuit-seal portion. The film-seal portion is bonded to the first film to surround the opening. The circuit-seal portion is bonded to the seal portion to surround the exposes portion. The device is formed with a closed space which is enclosed by the first sealing member and the second sealing member. The exposed portion is exposed to the outer space located outside the device.
Abstract:
An electronic device may be provided with printed circuits. Electrical components may be interconnected using signal paths formed from metal traces in the printed circuits. The printed circuits may include flexible printed circuits with bent configurations. The flexible printed circuits may be provided with integral bend retention structures. A bend retention structure may be formed from a polymer layer, a solder layer, a stiffener formed from metal or polymer that is attached to flexible printed circuit layers with adhesive, a conformal plastic coating that covers exposed metal traces at a bend, a metal stiffener with screw holes, a shape memory alloy, a portion of a flexible printed circuit dielectric substrate layer with a reduced elongation at yield value, or combinations of these structures. The bend retention structure maintains a bend in a bent flexible printed circuit.

A display device includes: a flexible first substrate; a flexible second substrate provided facing the first substrate; a display part; and a wiring substrate. The display part has a display component which is disposed between the first substrate and the second substrate. The display component produces at least one of an optical characteristic change and a light emission. The wiring substrate is connected to a connection pad provided on at least one of the first substrate and the second substrate. At least a portion of the wiring substrate is interposed between the first substrate and the second substrate outside the display part.

An apparatus and method wherein the apparatus includes a deformable substrate; a conductive portion; and at least one support configured to couple the conductive portion to the deformable substrate so that the conductive portion is spaced from the deformable substrate.
Abstract:
A method of manufacturing a concave connector substrate includes: a step of preparing a guide substrate having a guide/holding region that guides a plate-shaped connector to a connection position and a cut portion; a step of arranging and aligning two wiring substrates, each having wiring lines and through hole connection portions that are electrically connected to the wiring lines, with both surfaces of the guide substrate, and applying an adhesive to a predetermined region of the guide substrate to bond the wiring substrates to the guide substrate; a step of bending a portion of the wiring substrate toward the inside of the cut portion of the guide substrate and bringing the wiring lines disposed in the bent portion into pressure contact with the inside of the cut portion; and a step of removing a section inside the cut portion to form the guide/holding region.
Abstract:
A method and apparatus are provided for implementing interleaved-dielectric joining of multi-layer laminates. First and second multi-layer laminates are provided, each having with a laminated portion and an unlaminated portion. The first and second multi-layer laminates are joined together at the unlaminated portions by interleaving a plurality of dielectric layers of the first and second multi-layer laminates. Respective conductors carried by adjacent dielectric layers are connected. The interleaved unlaminated portions are laminated together with heat and pressure, to create a larger laminate of the joined first and second multi-layer laminates.
Abstract:
