Publication number: 20240107679Abstract: An assembly sheet includes a plurality of wiring circuit boards, a support portion, a connecting portion, and an opening portion. The wiring circuit board includes a first and a second wiring circuit board. The connecting portion includes a first and a second connecting portion connected to the first and the second wiring circuit board, respectively. The support portion and the connecting portion are not disposed between the first and the second wiring circuit board. The first wiring circuit board includes a first main body portion and a first protrusion portion. The second wiring circuit board includes a second main body portion. A first line passing a center of the first main body portion and a second line passing the center of the second main body portion are deviated so that a protrusion amount of the first protrusion portion with respect to the second main body portion is small.Type: ApplicationFiled: September 13, 2023Publication date: March 28, 2024Applicant: NITTO DENKO CORPORATIONInventors: Kenya TAKIMOTO, Hiroaki MACHITANI

Publication number: 20230240007Abstract: A wiring circuit board includes a metal support substrate, an insulating layer, and a conductive layer in this order in a thickness direction, and has an edge portion extending in a first direction. The edge portion includes a main structure portion and partially includes a partial structure portion. In the main structure portion, the metal support substrate has a substrate extension portion extending outwardly with respect to the insulating layer in a second direction perpendicular to the first direction and the thickness direction. In the partial structure portion, the insulating layer has an insulating layer extension portion extending outwardly with respect to the metal support substrate in the second direction.Type: ApplicationFiled: May 27, 2021Publication date: July 27, 2023Applicant: NITTO DENKO CORPORATIONInventors: Daigo TSUBAI, Naoki SHIBATA, Hiroaki MACHITANI

Publication number: 20230098947Abstract: A wiring circuit board includes two insulating layers, a wiring layer, a pad portion, and a conductive connection portion. The wiring layer is on one side in a thickness direction of the first insulating layer, and has a contact portion. The second insulating layer is on one side in the thickness direction of the first insulating layer to cover the wiring layer. The pad portion is on one side in the thickness direction of the second insulating layer. The second insulating layer has a through opening portion and having an opening along at least a part of a peripheral end portion of the pad portion. The contact portion of the wiring layer faces the through opening portion. The conductive connection portion, is connected to at least the peripheral end portion of the pad portion, and the contact portion, and electrically connects the wiring layer to the pad portion.Type: ApplicationFiled: February 24, 2021Publication date: March 30, 2023Applicant: NITTO DENKO CORPORATIONInventors: Shusaku SHIBATA, Hiroaki MACHITANI, Teppei NIINO
