Abstract:
A method of manufacturing a patterned conductor is provided, comprising: providing a substrate, comprising: a base material with an electrically conductive layer disposed thereon; providing an electrically conductive layer etchant; providing a spinning material, comprising: a carrier; and, a photosensitive masking material; providing a developer; forming a plurality of masking fibers and depositing them onto the electrically conductive layer to form a plurality of deposited fibers; patterning the plurality of deposited fibers to provide a treated fiber portion and an untreated fiber portion; developing the plurality of deposited fibers, wherein either the treated fiber portion or the untreated fiber portion is removed, leaving a patterned fiber array; contacting the electrically conductive layer to the electrically conductive layer etchant, wherein the electrically conductive layer that is uncovered by the patterned fiber array is removed, leaving a patterned conductive network on the substrate.
Abstract:
A metal-clad laminate according to the present embodiment includes an insulating layer, and a metal layer present on at least one surface side of the insulating layer. The insulating layer is a laminate of at least three layers of a center layer, a first resin layer present on one surface side of the center layer, and a second resin layer present on the other surface side of the center layer. The center layer, the first resin layer and the second resin layer each contain a cured product of a resin composition. Coefficients of thermal expansion of the cured products of the resin compositions contained in the first resin layer and the second resin layer are smaller than a coefficient of thermal expansion of the cured product of the resin composition contained in the center layer.

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.
Abstract:
A conductive pattern formation method of the present invention includes a first exposure step of radiating active light in a patterned manner to a photosensitive layer including a photosensitive resin layer provided on a substrate and a conductive film provided on a surface of the photosensitive resin layer on a side opposite to the substrate; a second exposure step of radiating active light, in the presence of oxygen, to some or all of the portions of the photosensitive layer not exposed at least in the first exposure step; and a development step of developing the photosensitive layer to form a conductive pattern following the second exposure step.
