Abstract:
An electronic device may have electrical components such as input-output devices. An electrical component may be mounted on a flexible printed circuit. The flexible printed circuit may have a bend that forms a flexible printed circuit spring to bias the electrical component in a desired direction. The electronic device may have a display with a display cover layer. In an inactive display area, opaque masking material may be formed on the display cover layer. A light window may be formed in the opaque masking layer. The flexible printed circuit spring may bias the electrical component against the display cover layer in alignment with the light window. An air gap under the electrical component may separate the component from a planar portion of the flexible printed circuit that is overlapped by the electrical component. The electrical component may be a camera, a light sensor, or other device.

Abstract:
An epoxy resin laminate comprising a center base layer of glass fiber woven cloth and outer base layers of sheet-like material more expansible and compressible than glass fiber woven cloth provided on both faces of the center base layer and integrally impregnated with composite produced by reacting polybutadiene-acrylonitrile copolymer having carboxyl groups at its terminal with epoxy resin having more than two functional groups.
Abstract:
The composite part is constituted by a plate of flexible material such as plastic which has electrical and/or thermal insulating properties, at least one face of the plate being provided with a metal cladding which is subjected to a photoetching process in order to form raised metallic portions corresponding to a printed circuit pattern, for example. Permanent deformation of the raised metallic portions can be produced by means of a mechanical cold-forming process without exceeding the range of elastic deformation of the flexible plate.
Abstract:
Some forms relate to a stretchable computing device that includes a stretchable body; a first electronic component embedded within the stretchable body; a second electronic component embedded within the stretchable body; and wherein the first electronic component and the second electronic component are connected by stretchable electrical connectors that include vias. The stretchable electrical connectors are non-planar and/or may have a partial zig-zag shape and/or a partial coil shape. In some forms, the stretchable computing device further includes a textile attached to the stretchable body.

Abstract:
The invention relates to an angle-adjustable and/or printed circuit board structure having at least two printed circuit board sections arrangeable or arranged angularly with respect to one another, wherein the printed circuit board structure contains at least one conduction element which is embedded at least predominantly in the printed circuit board structure and which extends between two contact pads and is electrically conductively connected to said contact pads, wherein the two contact pads are situated on different printed circuit board sections, wherein the printed circuit board sections are angle-adjustable and/or angled relative to one another with maintenance of the connections between the contact pads and the at least one conduction element and with bending of the at least one conduction element via a bending edge between the printed circuit board sections. In order to improve the electrical and mechanical connection between the printed circuit board sections, the invention provides for the conduction element to have a larger extent along the bending edge than perpendicularly thereto, as viewed in cross section. A corresponding method for producing this printed circuit board structure is like wise claimed.
