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.
Abstract:
The invention relates to an angle-adjustable and/or angled 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 connection locations and is electrically conductively connected to said connection locations, wherein the two connection locations 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 connection locations 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 likewise claimed.
Abstract:
A printed circuit board package structure 100 includes a substrate 110, plural ring-shaped magnetic elements 130, a support layer 140, and first conductive layers 160, 162, 164. The substrate has two opposite first and second surfaces 112, 114, first ring-shaped recesses 116, and first grooves 118. Each of the first ring-shaped recesses is communicated with another first ring-shaped recess through at least one of the first grooves, and at least two of the first ring-shaped recesses are communicated with a side surface of the substrate through the first grooves to form at least two openings 119. The ring-shaped magnetic elements are respectively located in the first ring-shaped recesses. The support layer is located on the first surface, and covers the first ring-shaped recesses and the first grooves. The support layer and the substrate have through holes 150. The first conductive layers are respectively located on surfaces of support layer and substrate facing the through holes.
