A method for manufacturing a wiring circuit board includes first forming an insulating base layer on a one-side surface in a thickness direction of a metal sheet, second forming a conductor layer on a one-side surface in the thickness direction of the insulating base layer so that a width of a wire is smaller than a width Wof a wiring body base portion, third forming an insulating cover layer on a one-side surface in the thickness direction of the wiring body base portion exposed from the wire so that the wire is covered with the insulating cover layer and a width of a wiring body cover portion is smaller than the width W, and fourth forming a metal supporting layer by etching the metal sheet from both sides in the thickness direction so that a width of a wiring body metal portion is smaller than the width W

Wiring circuit board and method for manufacturing same

A wiring circuit board assembly sheet is partitioned by a product region in which a plurality of wiring circuit boards serving as products are disposed in alignment and a margin region surrounding the product region with the margin region having a first area adjacent to the product region and a second area located at the opposite side of the product region with respect to the first area. The wiring circuit board assembly sheet includes a dummy wiring circuit board disposed in at least a portion of the first area and smaller than the wiring circuit board.

Wiring circuit board assembly sheet and producing method thereof

Provided is a method for manufacturing an organic EL device, including: a vapor deposition step of forming an organic layer over a substrate moving relative to a nozzle by discharging a vaporized organic layer-forming material through the nozzle. The vapor deposition step is performed so that a light emitting region formed of the organic layer and having a width A (mm) in a direction perpendicular to a direction in which the substrate is moving is formed, and so that W&#x2267;A+2&#xd7;h (where h&#x2266;5 mm) is satisfied, where a length of an opening of the nozzle in the direction perpendicular to the direction in which the substrate is moving is denoted by W (mm), and a distance between the opening and the substrate is denoted by h (mm).

Method and apparatus for manufacturing organic EL device

In order to provide an organic electroluminescent light-emitting device with less uneven brightness, which can be manufactured at low cost, a plurality of ribbon-like organic electroluminescent elements are connected to wires, which are connected to electrode terminals for energization at specific locations in a terminal region and mounted on a base material which has a substantially plate-like shape.

Provided are a method and an apparatus for manufacturing an organic EL device, which makes it possible to manufacture organic EL devices capable of suppressing quality degradation. The method for manufacturing an organic EL device, in which constituent layers of an organic EL element are formed by deposition over a substrate in the form of a strip, while the substrate is being moved in the longitudinal direction, includes a constituent layer-forming step of performing deposition over one surface of the substrate, while the substrate is being moved in the longitudinal direction, sequentially in first and second deposition units arranged along the moving direction of the substrate by discharging a vaporized material from an evaporation source. The constituent layer-forming step includes a plurality of upward deposition steps and a direction changing step.

Method and apparatus for manufacturing organic el device

Provided are a method and an apparatus for manufacturing an organic EL device which enable deposition of a vaporized material from an evaporation source onto a substrate in a desired pattern, while eliminating the need for a conventional strip-shaped shadow mask. A shielding portionis configured to be switchable between a shield position where the shielding portionis arranged between an evaporation sourceand a substrateso as to shield the substrateand a shield release position where the shielding portionis withdrawn from between the evaporation sourceand the substrateso as to release the shielding of the substrate. The shielding portionis switched between the shield position and the shield release position while rotating together with a roller
